PART B By : Helen Disler The farmer should observe closely the biological activity of farm soil. As in the physical aspects, all information should be written down in the farm's records for use in analysis and decision-making. Organic matter content should normally be measured in laboratory tests, but you can make a visual evaluation. Darker brown soil generally implies higher humus content. Dig up some soil and look for white threads of fungal mycelia and undecomposed organic matter. The absence of crop residues from the previous growing season within a few weeks of the new crop indicates the soil is biologically active. If residues are still present, you need to stimulate more soil organisms. Counting earthworms is a useful indicator of biological activity and overall soil health. Avoid taking the soil from spots that would overstate the worm count, such as under mulch or close to a compost pile. It is advisable to wait until a cool time of day so worms will not be exposed to harmful conditions. The earthworm census should be taken several times each season; the season average can be used to analyse year-to-year changes in soil health. You can pick any of these alternative methods for estimating earthworm population: Dig out everything in a 12-in x 12-in x 6-in (30.5-cm x 30.5-cm x 15.2-cm) plot and place in a pan or bucket. Good healthy soil should contain 10 or more earthworms in a sample this size. Dig out a "spade-split" of soil, about 2-in (5-cm) wide and 8-in (20-cm) deep (the spade blade serves as length). There should be several spade-splits taken from each field, and the average for the field is calculated. For each spade-split, one earthworm is roughly equivalent to 100,000 worms per acre (247,000 worms per hectare). This is the simplest: just count the number of earthworm holes (marked by the earthworm castings beside them) in a designated area. The same area should be used for subsequent counts during the season, to make the year-to-year numbers comparable. Plant root condition can be considered an ultimate indicator of soil health. Examine the roots of a weed or a growing plant. If you dig up a plant, take care to cut off the least possible portion of its root mass. Select the healthiest-looking specimen in the area and evaluate. Are roots well-branched and vigorous? It is desirable for roots to penetrate as much soil area as possible. The estimated volume and depth of the root mass in the area, tracked over the course of the season, indicates changes in the soil biological health. Are fine root hairs plentiful? The presence of many fine feeder roots indicates good air circulation in the root zone. Are roots spreading out in every direction, or are they growing sideways at some point? A sudden change of direction sideways indicates the presence of an impenetrable hardpan underground. Legume crops should contain a good number of nodules, which are the living areas of nitrogen-fixing bacteria. Slice open some nodules and check the colour inside. A healthy nodule presents a pink or red colour; green or black indicates lack of bacterial activity (although this may be the temporary normal colour, when the plant is entering its dormant phase). The more and the bigger the nodules, the more nitrogen the plant can fix. Beans and peas normally have fewer nodules than clover and alfalfa. Close, regular, and accurate observation and recording of information about the soil's physical and biological condition, combined with crop health and yield records, provides a sound basis for evaluating the fertility improvement program.

How Do Farmers Observe the Health of their Soil and What Tools do they Use? PART A By : Helen Disler Farmers know that soil health is critical to their success. They thus learn to observe nature keenly and to use their observations for refining their farm management practices. Written records are important tools and the farmer should use them to keep track of all information about individual fields. It is easy to evaluate the general tilth and physical aspects of the soil even without using precision instruments. It helps to repeat some tests one or more times a year to see the progress of your soil-improvement program. Texture influences water and nutrient-holding ability. Get a handful of moist soil and squeeze it into a ball. If it falls apart when you open your hand, the soil is sandy. If it remains a ball, squeeze some of it between your fingers and form as long a ribbon as possible, and measure it. If making a ribbon is not possible, the soil is loamy sand. Add some water to the ribbon in your hand until it becomes liquid mud. Feel the mud with the forefinger of the other hand and decide if it is mostly gritty, mostly smooth, or equal parts of both. Soil that forms a ribbon shorter than 1" is sandy loam if it feels mostly gritty, silty loam if mostly smooth and, loam if equally smooth and gritty. A ribbon of soil 1-2" long is sandy clay loam, silty clay loam, and silty clay, respectively. Moisture readings should be taken when the crop is started and several times afterwards. If soil moisture down to a six-inch depth is less than 50%, you will need to add water. Look at the soil for signs of dryness (crusting, cracking, etc.) and see how far down before soil gets darker, indicating more moisture. Get a few handfuls from various depths and squeeze firmly. If your hand gets wet, the soil is saturated. Moisture is probably 25-50% if light-textured soil does not form a ball, medium-textured soil tends to crumble but holds under pressure, and heavy-textured soil is somewhat pliable and balls with pressure. Drainage problems are easily detected. Fill a 12-inch deep, 6-inch diameter hole with water and let the water drain completely. When the water is gone, fill the hole again and observe how long complete draining takes this time. If it takes more than eight hours, drainage is an immediate problem to address. Water infiltration rate gives you an idea of soil porosity. Bring one quart of water, a tape measure, and a stopwatch. The test should be done when the soil is equally dry and wet. At soil level, empty the water and count how many seconds it takes to soak into the ground. Measure the diameter of the wet spot and multiply the diameter by the time. Test the soil several times during the growing season, using exactly one quart of water each time. Over the years, subtle changes become apparent. A declining trend indicates an improving capability to absorb water. Structure and size of soil aggregates and how well they hold together are important aspects of tilth. Soil with good structure holds about two times more water than soil of the same texture but with poor structure. Get some soil and observe how it crumbles in your hand. If well structured, heavy soil still crumbles easily whilst light soil keeps some shape without becoming powdery. If poorly structured, heavy soil resists crumbling whilst light soil becomes powdery. Evaluate aggregate stability by placing several large crumbs (up to one-half inch) in a glass filled with water. If many crumbs hold together, the soil has good structure.

Why Buffer Weedicides and How Do You Do It? By : Helen Disler Weeds are considered significant threats to natural ecosystems. To the farmer, weeds are also a major threat to farm economics. Weeds interfere with crop growth, choke pastures and may even harm farm animals. Being plants themselves, they compete with crops for soil nutrients and water, leading to poorly growing crops and reduced harvests. A quick, cost-effective way to combat weed invasions is to apply weedicide. These are dangerous chemicals, however, and you need to provide for adequate protection to prevent the weedicide from drifting to other places in the farm or, worse, to your neighbours. To limit the extent of weedicide drift on adjacent areas, farmers usually block off an area between the zone to be sprayed and the zones to be protected from drift. This is called the buffer zone. In many cases, the buffer zone consists of vegetation -- a stand of tall grasses, shrubs, or trees; sometimes, a strip of paddock left alone without spraying can serve as buffer. It is usually located downwind relative to the sprayed zone, since chemical droplets are wind-borne. Vegetative buffer zones help localise the drift of sprayed weedicide by catching on their leaves and other plant surfaces (stems, flowers, etc.) the spray droplets carried in the air. There are limits to their filtering capacity as, for instance, when the wind is blowing too strongly; they also cannot capture fine vapours or odours of the chemical. When establishing a vegetative buffer zone, it is preferable to select plants with numerous surfaces that present small frontal areas to the droplets. Filters normally work better when there is more surface area available to catch the target particles, and the same is true for vegetative buffers. Thus, plants with needle-like foliage and plenty of small branches are better at capturing droplets. Large leaves may still be suitable if the surfaces are covered with small hairs or other protrusions. To guard against having gaps in the lower portions of the vegetative buffer, mixed plantings may be done to have different heights of vegetation. The buffer zone design should try to achieve the maximisation of surface area for droplet capture and, simultaneously, the minimisation of interference with the direction of airflow around the barrier. The objective of reducing airflow deviation differs somewhat from that of shelterbelts, which seek to change the wind direction away from the leeward side. Having a slight wind passing through the buffer will increase the chances for droplet capture. This argues for a vegetative buffer with adequate porosity to allow the air stream to pass through the barrier instead of above or around it. Wind experiments have established that a porous buffer is able to capture greater amounts of droplets than a solid buffer. This finding suggests that the height of the vegetative buffer should be significantly higher than the height at which the weedicide spray is released. The rule of thumb is that a buffer should be at least two times higher than the release height. For instance, if one is hand-spraying weedicide at a release height of 1.5 metres, the vegetative buffer should be a minimum 3 metres high. It has been calculated that the 2:1 ratio in heights provides spray drift protection equivalent to 3-10 buffer heights downwind. More amounts of spray drift will be intercepted when the vegetative buffer is located closer to the release point. What Robot Would You Need? By : Andrew Newell Robots are automated machines that will address specific needs and will perform pre-programmed tasks. They can be useful for menial labor or delicate jobs thanks to breakthroughs in precision engineering and programming technology. Robots of Fiction and Reality By : Andrew Newell As any science fiction reader would know, there are a lot of discrepancies between what reality is and what is only in fiction. As science fiction is the branch of literature that delves most into what the future holds for us, science fiction stories serve as an intellectual forecast into the direction our technology is headed. Still, much remains to be accomplished. Other Possible Applications of Robots By : Andrew Newell Currently, we are enjoying the benefits of the advancements in the field of robotics. Many factories and other industrial facilities utilize robots for both manufacturing and research. In medical facilities, robots are used in order to ensure the precision measurements required when mixing chemicals. Japan; the New Birthplace of Robots By : Andrew Newell Japan is the country that gave the world giant robots, small robots and human sized robots. From the fictional Mobile Suit Gundam to the small tea-making robot maid, Japan’s robotics technology has been pushing the limits of our minds and imagination. A Look into the Morality of Military Research into Automated Robots By : Andrew Newell The concept of a robot soldier has long been etched into society with the help of media and science fiction. Indeed, the concept of an automated machine going to the battle field plants the idea that wars would bring less death as a result of having less human soldiers on the field. Why Higher Brix Readings in Forage Makes Animal Raising More Profitable? By : Helen Disler The Brix reading on a plant is an indication of its nutrient content. Whilst the reading is often considered as the sugar content in that part of the plant being tested, it actually refers to the total amount of soluble solids, that is, sugars along with plant proteins, vitamins, and minerals. The higher the Brix reading the greater is the amount of nutrients. A Brix reading lower than 10 tells the farmer that the plant lacks nutrients. It must be said that although there may be an abundant supply of nutrients in the soil, it is still common to get low Brix readings. The desirable reading is one above 12, which indicates a robust and nutrient-rich plant. In addition to high nutrient content, high Brix indicates a bigger specific gravity and less water in the plant fluids. High-Brix plants have also been observed to demonstrate greatly improved resistance against the majority of insects that feed on plant sap such as aphids, cucumber beetles, white flies, potato beetles, leafhoppers and other sap suckers. If people were to eat high Brix foods, they would obtain much more nutrition than from low Brix foods from equal quantities. It can happen that less amounts of high Brix food will be needed to provide the same level of nutrition they are getting now. The same thing would be happen among livestock and other animals. Merlin Nussbaum, a farmer of 20 years' experience and currently working as an agricultural consultant, has worked with many farmers rearing livestock and producing animal feeds. In his work, he has seen first-hand the more effective resistance to pests in high Brix crops. Nussbaum still remembers a crop of alfalfa that registered a Brix reading of 16 a few years ago (the consistent observation among savvy farmers is that plants with at least 12 Brix exhibit high pest resistance). In this particular alfalfa field, the consultant distinctly observed that there were many leafhoppers massing on the boundaries but the insects simply would not enter the field. The absence of infestation in the alfalfa field resulted in a large yield and greater profitability for the crop. If this had been a forage crop, the farmer would have reaped a very nutritious and bountiful harvest. Such a harvest would have provided a lot of nutrients at a low effective cost when fed to livestock. The animals would achieve good body weights from a lower-cost feed input, making the enterprise much more profitable. It has also been observed that when given high Brix grass, cows eat only half of the amount of grass they would eat when fed low Brix grass. The pasture, which had a high Brix, consisted of various grasses including fescue and timothy. In this case, the cost of forage fed to the cows was immediately reduced by half. Dairy cattle fed with high Brix grasses increased the quantity of their milk production. The cattle were healthier because of the nutritious food, resulting in vastly lower veterinary bills for the farmer. In addition, the milk produced had a yellower, creamier colour, a desirable quality attributed to more carotene contained in the high Brix grass. High Brix forage thus increases production in farm animals even as it lowers production costs. The combination of these factors adds up to more profits for the farmer. The Detrimental Effects of Chemicals on Soil Fungi By : Helen Disler Fungi and bacteria in the soil are the primary recyclers of nutrients in the soil. Whilst bacteria are much more numerous, fungi provide greater biomass because they are relatively bigger. Fungi may be responsible for greater amounts of nutrient retention and soil organic matter formation than bacteria. Decomposers. Saprophytes play key roles in SOM production because of their ability to help decompose both plant and animal remains, including animal dung. Animal hair, hooves, claws and feathers become food for particular fungal species, and many moulds thrive on animal droppings. A succession of saprophytes colonise debris on the ground. Sugar fungi break down simple sugars but not the complex sugar chains known as cellulose and hemicelluloses, or the lignins that hold them together. Sugar fungi are eventually replaced by brown rot fungi, which digest cellulose and hemicelluloses and, when they have accomplished their work, leave behind a brown, crumbly residue rich in lignin. The white rot fungi that replace them have the ability to digest lignin, the residue most resistant to decomposition, and leave behind wood strips that look bleached and stringy. Parasites. Parasitic fungi can seriously damage crop plants. The presence of a host plant is necessary for parasitic fungi to proliferate. Normally, they are specific to certain crops or species, but some can affect several plant species. Continuous planting of the host plant will encourage growth of parasitic fungi, so it is important to promote high biodiversity in farm soils. Mutualists. Called mycorrhizae (myco=fungi; rhizo=root), these fungi invade plant roots but form mutually beneficial relationships which result in better plant nutrition. Many plants probably cannot survive without the mychorrhizae. They extract sugars from plant roots to obtain energy. In exchange, plants gain a lot more in terms of root protection from soil-borne disease-causing organisms and parasites, and better growth rates. Mychorrhizae also produce glomalin, a type of protein, which is important in soil aggregate formation. Glomalin acts as a glue to bind plant cells, fungi, bacteria and microorganisms with soil particles to form larger particles of organic matter which help in providing good soil porosity, promoting water infiltration, and facilitating drainage. At least 90% of agricultural plants form symbiotic relations with mycorrhizae. In terms of interaction with cultivated plants, the mycorrhizae would be of greatest interest to farmers. Mycorrhizae promote root development, increase uptake of nutrient elements (especially nitrogen and phosphorus), protect plants against pests, diseases and drought, and improve soil aggregation. The detrimental effects to farm soil, and consequently farm yields, from the use of chemicals involve the mycorrhizae. Insecticides and systemic fungicides can decimate mychorrhizal populations when applied, while herbicides may remove plants that affect fungi distribution. Methyl bromide, a broad-spectrum biocide, is usually used to kill parasitic nematodes and pathogenic fungi, but it also kills mycorrhizal fungi. Mycorrhizae also become ineffective in soil conditions where nutrient levels are very high or very low. In very low nutrient-level conditions, their sugar extraction activity from plants has a parasitic effect. Their effectiveness is reduced when there is a good supply of phosphorus. Generally, mycorrhizae are most efficient in soils of relatively low fertility that receive little inorganic fertiliser. They are also quite active in soils with ample organic matter, where crops are rotated but with little or no tillage. If You Are Using Chemical Fertilizers, How do these Affect Brix Meters results? By : Helen Disler People today are more conscious about the nutrition content of the foods they eat. Farmers who are able to provide highly nutritious food will receive premium prices and have many repeat customers. Farmers can have food labs test for the nutrition content of their produce. The nutrients of interest in such tests may include calcium, selenium, magnesium, iron and perhaps others. The only drawback is that testing costs money and the more elements tested, the higher the cost. A simpler and more inexpensive field test for nutrient content is the Brix meter reading on a plant's sap or juice. Brix readings on plant juice/sap are a measure of something fundamental and unique to plants -- photosynthesis. Plants are the only creatures on earth that use water and carbon dioxide with sunlight and chlorophyll to produce sugar. Everything harvested in the farm, every carton or ton of yield, originates from this sugar. But it is not only sugar that is found in brix; there are also vitamins, amino acids, and other nutrients. The brix level is an accurate indicator of the nutrient density of a crop at the time the reading is taken. As a provider of food and promoter of health, the farmer needs to manage things to raise the brix value on the growing crop. Regular brix readings will give the farmer the chance to react -- that is, to apply the fertility practices necessary to increase the brix reading (therefore, the nutrient value) of the crop. According to Dr. Carey Reams, a renowned agricultural consultant who was the first to devise a reference index of "poor" to "excellent" brix readings for crop juices, it does not matter much to the plant where a nutrient comes from, i.e., whether the nitrogen, for example, is from an organic source or from chemical fertilisers. The important thing is that the nutrient applied in the fertiliser is the substance the plant needs at the time. If the chemical fertiliser has the nutrients the plant needs, the brix reading will rise. If the brix remains unaltered or falls, the substance is not the nutrient needed, or may be in an unusable form, or is detrimental to the plant. It is important, according to Reams, that the farmer be methodical in applying the chemical fertilisers. It is not enough, for example, that the farmer simply scatters a certain number of pounds or tonnes of ammonium nitrate on a given area. He developed a method for calculating the exact amount of energy released by one molecule of ammonium, which could then be used to determine the amount of fertiliser to apply. Reams' method helps farmers to avoid the common mistakes of conventional farming with chemical fertilisers, where excess amounts are likely to be applied which leads to waste and ground water contamination. But if too little is applied, the yield on the crop will be limited. Brix readings will rise significantly when too much nitrogen-rich fertiliser is applied relative to the actual needs of the crop. But the pest-resistance phenomenon often observed in plants with high brix will not happen; the crop will attract a lot of pests instead. Plants high in nitrates have too many free amino acids circulating in their system, waiting to be synthesised into complete proteins. These free amino acids attract insects, which prefer them over complete proteins. The farmer should target for brix readings of at least 12. The key to heavy crop yields is to ensure that nutrients are supplied in the right quantities and in the forms plants can use. How Do Plants Get Nutrients in the Soil in a Conventional Farming System? By : Helen Disler Plants need an adequate supply of nutrients -- particularly nitrogen, phosphorus, and potassium -- to grow well. Ideally, these nutrients should be available in the proper quantity and at the time the plant can use them. This ideal timing, if complied with, will help farmers avoid supplying an excess of nutrients that plants cannot use anyway and may become contaminants in the environment instead. Nitrogen, phosphorus and potassium are the nutrient elements most needed in large amounts by plants; however, they are not available in adequate amounts in the soil. Nitrogen is important for plants because it is a component of proteins and chlorophyll, the active pigment in photosynthesis; it is a constituent of nucleic acids and coenzymes that catalyse cell reactions. Phosphorus is also found in proteins, coenzymes, and nucleic acids; it is critical in metabolism and chemical energy generation and utilisation in the cells. Whilst its role is not clearly defined as a component of the various chemical compounds that make up the plant, potassium is important in the physiological mechanisms that regulate plant processes, particularly the all important processes of photosynthesis and carbohydrate translocation. In conventional farming systems, nitrogen, phosphorus and potassium are supplied to the soil by application of inorganic fertilisers at levels recommended by soil testing technicians. The caveat is that variable conditions in the soil and the climate affect the rate of uptake or loss of nutrients in ways not yet fully understood. The ability to forecast factors that influence the storage, cycling, availability and uptake of nutrients is still relatively inadequate. This makes it difficult to predict the proper, environmentally safe levels of nutrients. Consequently, the application recommendations that farmers receive may just as easily lead either to insufficient or excessive fertilisation. Working out the appropriate dosage amounts to apply may be tricky. Phosphorus fertiliser undergoes rapid conversion into less soluble compounds in acidic or alkaline soil, which then severely limits their availability for plant nutrition. Even if they are in available forms, the phosphorus may be tightly bound to organic soil compounds and clay, and remain locked in soil, inaccessible by plants. On the other hand, potassium and nitrogen (in its ammonium and nitrate forms) have greater solubility than phosphorus. Nitrate ions will leach readily into the soil, thus nutrient applications are susceptible to significant losses. Potassium and ammonium nitrogen are positively charged and are held on by negatively charged soil in the cation exchange, thus leaching will not occur in appreciable amounts except in sandy soils. Whilst there is understanding of the basic process, agriculture scientists need more information about nutrient cycling and nitrogen behaviour under various environmental conditions. As a result of this difficulty, it is not surprising -- and many studies have found -- that recommended fertiliser doses worked out by some commercial soil testing laboratories consistently required far more fertiliser than was needed. Not only that, some farmers tend to apply greater amounts of nitrogen than recommended. However, with susceptibility to leaching and/or rapid conversion into insoluble forms, there is still no guarantee that the fertilisers will still be available to plants at the time plants have need for them. UID Registry Data Submission Information By : Id Integration Submission of UID data to the UID Registry is crucial for the DoD contractors and hence, it is vital for them to learn various aspects of submission process. Soil Testing: A General Overview By : Helen Disler It is important for farmers to monitor the health of the soil, which produces the plants from which farmers make their living. One of the critical activities in this regard is periodic soil testing. Ideally, soil samples for soil testing are done shortly before making a land management decision -- which may be several months in advance of planting. The results represent the most current indication of soil properties, giving enough time for the objectives of the decision to have impact. For example, to see if limestone should be added to correct soil acidity, soil testing should be done several months before planting to give the limestone sufficient lead-time to react with the soil. Soil testing well in advance of planting provides leeway to make changes if unsuitable growing conditions are found. Sampling depth is crucial, and this depends on your planned crop and the type of soil test to be carried out. Routine soil tests usually require samples obtained from topsoil (0-20 cm depth), but soil tests for mobile soil nutrients (such as NO3-N and SO4-S) may require samples from deeper levels. When collecting subsoil samples take care to avoid contaminating the subsoil with topsoil; contamination can seriously throw off the results and the ensuing recommendations. There are three types of soil tests: chemical, physical and biological. Chemical testing helps determine the soil chemical properties that might constrain plant growth. In chemical tests, the analyst assesses the nutrient-supplying capacity and other chemical properties of the soil known to influence plant growth such as pH, soluble salts, and soil organic matter (SOM) content. The most common methods in use are extraction, equilibration, titration (usually for acidity measurements) and oxidation (by chemical or thermal means, to test for SOM). In chemical extraction, soil samples are dried, ground to fine particles and sieved. Usually, 1 to 10 grams of sample are placed in an extracting vessel and mixed with an extracting solution of pre-determined volume (from 10 to 100mL). The mixture is shaken vigorously for about 5 (or up to 30) minutes and poured through a filter. The analyst then examines the filtrate for the elements of interest. Equilibration involves adding a solution to the soil and, after shaking or letting stand the resulting soil suspension for a short time period, measuring some property of the mixture. Soil pH, lime requirement and soluble salts are measured using this method, although some laboratories may alternatively use titration techniques to measure soil acidity. Wet chemical oxidation measures SOM from the quantity of carbon that can be oxidised by potassium chromate (K2Cr2O7). Issues about the environmental impact of chromium use and disposal have led to the growing popularity of thermal oxidation, using high temperatures (360oC or 680oF) to estimate SOM from the differences in sample weight before and after ignition. Physical tests assess the physical properties of soil that influence growth. The most common test in use is the evaluation of particle size of soil and its distribution. Water-holding capacity may be tested in particular situations, to determine water movement and retention, which help in assessing irrigation potential and setting irrigation schedules. Biological tests are important because the level of biological activity in soil substantially affects plant growth. It is also essential to know if plant pathogens are present in the soil. Earthworms, tiny organisms, and microscopic fungi and bacteria all contribute to a growth-promoting soil environment. Organism activity can also serve as an indication of the state of the soil ecosystem, since they simultaneously influence and are influenced by the physical and chemical condition of the soil. How to Find Healthy Soil & Biological Soil Testing By : Helen Disler Modern agriculture has placed greater emphasis on the development of sustainable farming systems. This has led to greater interest in farm management practices that promote the biological aspects of soil fertility. To help farmers in this regard, many approaches to soil biology testing have been developed, which can be classified into tests for population analysis, biological activity, and indirect indicators. Population tests look at the types and numbers of organisms present in the soil. Know About Digital Printing By : LYMA LYMA Digital printing on fabrics started around 1994.

What You Need To Consider Before Building Your Dream Log Cabin By : John Maltakiso Log houses are a extremely popular choice among American house owners because of their charming appearance and rustic feel. Log homes, often known as log cabins, are often made from wood that has not been lumbered at all, or those that have only been lumbered a little. How Do You Do A Chemical Soil Test? By : Helen Disler Chemical analysis is the most common method used to assess the nutrient content (and nutrient needs) of soil. An accurate determination of nutrient need is possible if two conditions are satisfied: first, that the soil sample is truly representative of the field to be analysed; and, second, that the chemical testing method has been calibrated through enough research to the crops and soils in the area. The farmer may choose to take soil samples either by soil type or on a grid basis. Soil-type sampling involves making a diagram of the field by soil type and obtaining a composite sample of each type. The composite sample may consist of 10 to 15 individual cores of each type which are thoroughly mixed together. From this mix, about 1 pint (0.5L) or 1 pound (0.4kg) is submitted to the lab for testing. This process is done for each soil type present in the field. Grid sampling involves dividing the area into squares of 1.2 to 2.0 ha (3-5 acres) and taking from each square a composite sample consisting of 8 core samples thoroughly mixed together. Contamination of samples should be avoided. The lab may also want historical information about the field, such as cropping history for two years or more, previous applications of fertiliser or manure, yield levels, etc. It is advisable to have the samples analysed by a reputable lab whose technicians are well-acquainted with the soils and crops in the farm's locality. The information generated from the chemical tests gives an indication of the soil quality in the field. Soil organic matter (SOM). Labs use chemical or thermal oxidation of the total soil to determine SOM. Since the carbon content of SOM is typically around 58-60%, a factor of 1.7-1.72 is used to convert soil organic carbon content into SOM. An organic carbon content value of 0.8%, for example, translates into an organic matter content of 0.8% x 1.7 = 1.36%. Larger values of SOM are desirable because SOM enhances water retention as well as nutrient retention properties of soil, making these available to plants. The lab will have to indicate an optimal SOM value for your area. SOM values that decline over time indicate deterioration in quality. Soil reaction (pH). The soil reaction or pH value, measured from soil slurry, is dependent on the type and quantities of organic and inorganic materials. However, environmental and management action also affect pH. Excessive nitrogen fertilisation makes soil acidic, whilst poor management of irrigation can induce alkalinity in soil. A soil pH analysis gives data about active acidity (or the hydrogen ion H+ in solution); in contrast, a test for lime requirement evaluates the reserve acidity (or the buffering ability) and provides an accurate guidance on how much lime to apply to a particular field. Nutrient Availability. Soils can be analysed for virtually all nutrients but within limits. The more routine chemical tests are for phosphorus, potassium, calcium, and manganese -- all of which significantly influence plant growth. There are specific tests tailored to specific soil types and crops. A recommended test will generate data expressed in units of nutrient content per hectare (e.g. kg/ha), and these values will be compared with an appropriate scale defined by local technicians. Chemical soil testing may have the most accurate results in soil testing because they entail precise measurements of nutrients detected in the soil. Selection of the method is a decision made by the lab scientists, depending on the facilities available to them. The farmer's role is to submit the most representative, contamination-free samples of the soil in their fields. Industrial Water Treatment: Objectives, Classifications and Applications By : Rich M.

"Rudolf Steiner" in Relation to Biodynamics By : Helen Disler Rudolf Steiner was an Austrian philosopher, architect, esotericist, educator and social thinker born in the early 1861 and died in the early 1925. Steiner achieved initial acknowledgment as a cultural philosopher and literary reviewer. After the First World War was over, Steiner strived to find realistic demonstrations of his philosophy in collaboration with educationalists, farmers, medical doctors and other fields. He instituted biodynamic agriculture, Waldorf education and anthroposophical medicine among other numerous biodynamics aspects. Biodynamics or biodynamic agriculture encompasses a sustainable and ecological farming technique that comprise of many thoughts of organic farming. In the year 1924, an assembly of farmers anxious about the prospect of farming requested Steiner' to assist them. Steiner acted in response with a series of lectures about agriculture. This formed the foundation of biodynamic agriculture, which is now widely practiced all through much of North America, Europe and Australasia. A vital concept of the lectures was to "personalize" the ranch or farm by carrying no or a small number of external materials for use on the farm. However, the farmers generated all needed resources such as animal feed, manure or fertilizer from within and referred to it as "farm organism". There were various characteristics of biodynamic agriculture moved by the lectures given by Steiner. This includes the timing of activities, for instance, planting in accordance with the patterns of the planets or moon's movement. This must have been developed in precise ways, to compost piles, plants and soil with the objective of appealing to non-physical life forms and essential forces. Steiner further advocated for the farmers to scientifically verify the suggestions that he had put across in the lectures since he had not verified. In the earlier years of the twentieth century, adoption of conventional agriculture gained momentum with the use of nitrogen based inorganic fertilizers. These were manufactured through condensation of nitrogen from the air and consequently applying it to the fields. Steiner believed this chemical farming was detrimental to the environment and clearly stated that application of chemical fertilizers is an action that must be stopped. This was because the crops grown on the field after a period of time ended up losing their nutritional values as a completely general law. Steiner was certain that chemical farming through the use of pesticides and artificial fertilizers would lead to the degradation in the food quality produced. Steiner also believed this was not only because of the biological or chemical nature relating to the materials involved. He believed that it was also caused by the divine inadequacies in the entire chemical move towards farming. Steiner believed in monism, which considered the mutually exclusive material and spiritual nature of each and everything in the world. Steiner believed that there is a sharp difference between living and dead matter, thus synthetic nutrients were very much different from the living microbial made nutrients. The name " biodynamic" or "biologically dynamic" was carried forward by Steiner's supporters. The core aspect of biodynamics hold that, farm in its entirety is viewed as an organism and consequently ought to be a bunged self-nourishing organism, which the measures nourish. Ailment of organisms is not tackled in isolation since it is an indicator of problems in the whole life form. Rudolf Steiner is applauded for establishing various aspects of biodynamics that have proved to be very useful to educationalists, farmers and medical doctors at large. Introduction to Precast Concrete Structures By : James Soul1 Precast concrete structures requires a restructuring of the entire conventional construction process to enable interaction between the design phase and production planning in order to improve and speed up the construction. So You Want to TIG Weld! By : mdtread It is like a rising superstar in this day in which we live. The art of TIG welding has been around for some time but is becoming an ever popular application for welding. It is drawing upon the curious side of someone already interested in the field of welding. TIG welding is a very unique form of welding. When you begin to use the left and right hand simultaneously in any process there is more stress involved to the welder and this technique requires more agility than does the more common practices of welding. When you embark upon a career in TIG welding there are normally pre-requisites that have already been achieved by the time you arrive in the TIG domain. Stick welding is normally a foundation before a welder steps into the world of TIG. Rarely does the TIG process stand alone. There are places that you find the MIG and TIG process alone but those areas do not entail the vast majority. Some places you may see just the TIG would be the Aero-Space Industry, lightweight bicycles, hospital equipment, dairy production, etc. For the most part, the TIG process will find you in the Petro-Chemical Industry, Chemical Refining, and the Fossil Fuel Industry. Power plants, refineries, chemical plants and the likes is actually the place that the biggest money is made as well as the pipeline; which used to be downhill stick only and reserved for the welder with the big head and the rig truck he worshipped as a god. Things have come a long was needless to say. The welder in general used to have an upper-hand in his craft but not so any more. Most people in these industries look at the welder in general as a cry baby and whiner who is always looking for the ideal conditions in which to perform his operation. But! The TIG welder is someone that is still in high demand and carries some prestige connected to his ability to be ambidextrous. The TIG hand can weld stick, MIG, TIG usually whether it is carbon or alloy metals. The further the welder can move into the realm of the exotic, the more in demand he becomes. The more certifications he can obtain, the more in need he will find himself (or herself). The bad part about the area of TIG welding that we are talking about at this stage is the different environments that go with this type of welding. The already mentioned places that usually call for this type of welding are not the most pleasant places to work. These type of environments eventually take a toll upon the body of the individual. It is not easy to sustain good optimal health in fume and particulate saturated environments. Toxins and poisons are present. Elevated structures with scaffolding enclosed by fire retardant blanket. Noise levels that can and most of the time due require hearing protection. Come to think about it, the bike factory is becoming more appealing all the the time. LOL! Actually, a good TIG hand that is respected in his trade can call the shots. He sizes up the fit on pipe and if it isn't correct he shoots it down, because once he starts welding on it he has taken the responsibility in saying I can make it happen. A good TIG welder can make a bad fitter look good. Or take a bad fit and turn the fabricators heartburn into Rolaids to the rescue. An older man that has become well versed in his trade is widely respected by his peers when he becomes known as the TIG daddy, the man, the khaki daddy, etc. There are up and coming young men that are always following in the footsteps of the well accomplished mentor TIG welder. TIG comes with a few essential items that must be recognized. Clean clothes every morning with starched shirts and a nice skull cap. A bandanna in the back pocket. A bandanna around the neck like a businessman would wear a tie to the office. Fairly new looking gloves that are not your run of the mill leather. TIG welding requires sensitivity in the fingertips and hands. Most of the time a good TIG hand has cash in his wallet and is on top of his game. The problem we see with that in our economy is that he has to travel a bit more than he would like to keep that going. The benefit of that is that he will always have a job because of his skills. You see the TIG welder is selling his skill. He doesn't produce a product so to speak. His arsenal of tools contain his favorite hood or two, small hand tools that are used to accent his skill. Sharp tungsten stored in his tool bag or bucket. Files, die grinders, small wrenches, flapper wheels, emory cloth, filler rod, a coffee thermos (very important), extra gloves and lenses if needed, and possibly some small fit up wedges or flat head screwdrivers. In our next article we will look at the actual components of his equipment for a further breakdown in lesson TIG 102. Until then, thanks for your time and take care!

Harnessing Cosmic Energy for Profitable Farming By : Helen Disler Biodynamic agriculture, or simply 'biodynamics,' is a farming system based on deep ecological principles that arose as a reaction to the spread of specialised agriculture and inorganic fertilisers at the turn of the twentieth-century. In terms of methodological beliefs, biodynamic farming stands apart from other systems with its use of nine distinct preparations, consisting of extracts from various sources (minerals, plants, and animal manure) which are applied in minute proportions to plants, the soil, or compost. In many ways, biodynamics is similar to traditional organic farming systems, especially in the biological and cultural principles guiding its farming practices. However, it is distinct from other organic farming systems because it incorporates into its farming practices certain spiritual principles that aim to tap into cosmic and non-physical forces believed to exert an enriching influence on the farm and on the living organisms (human and non-human) that inhabit it. Biodynamics thus combines biological practices, such as established organic farming methods that bolster soil health, and dynamic practices intended to enhance its metaphysical aspects (such as boosting the farm's life energy) and make the farm's rhythms coincide with Nature's (such as scheduling planting in time with the phases of the moon). In encouraging planting by lunar phases, biodynamics acknowledges that in the same manner that the Earth's tidal movements and magnetism are influenced by its relative positions to the moon and the sun, so are the phases of plant growth. The idea is that the waxing and waning moon phases exert different influences on plants. The biodynamics planting calendar recognises that in the days leading to the first quarter, the moon's gravity is weakening relative to the Earth's but intensity of moonlight is increasing. It is believed that this lunar phase induces good growth of both the root system and the leaves. Growth is increasing in a balanced manner. In the second quarter leading to the full moon, lunar gravity grows stronger relative to Earth which leads to slower root growth. But leaf growth continues to spread as moonlight approaches full intensity. If root development has been good in previous stages, the root system will be able to efficiently deliver water and nutrients to the leaves, resulting in good growth. During the third quarter period, decreasing moonlight and weakening lunar gravitation suggest different activities for the biodynamic farmer. At this stage, leaf growth slows down whilst root growth picks up again as Earth's gravity tugs at the plant's roots. The third quarter is a good time to transplant seedlings since the roots are active -- minimising shock of transplantation and enhancing development of the root system. Seeds with long germination times (more than two weeks) should be sowed at this time to put them in good position for sprouting in the subsequent new moon to first quarter period. In the fourth or last quarter, there is no moonlight and relatively stronger lunar gravity. Both root development and leaf growth will slacken. Where there was balanced surge in growth during the first quarter, there is now a balanced slowdown in growth during the last quarter. In the biodynamic planting calendar, this is a period of rest for the plant, giving it time to prepare for the next surge with the onset of the next lunar cycle. Biodynamic practices also recognise other forces beyond chemistry, physics and gravity. Vital life energy and astral forces are integral parts of biodynamic agriculture. For the biodynamic farmer, farming is not just livelihood; it is a way of life. Why is The Life in Your Soil So Important? By : Helen Disler The entire food production system depends for its viability on healthy soil. Healthy soil produces the healthy crops that give nourishment to people. Organic farming is intimately related to the concept of soil health because its advocates have always believed that a healthy soil is the key to the sustained production of healthy, nutritious food. The main indicators of soil health are the amount of fresh organic matter and the level of biological activity. Soil is a living ecosystem, and health Float Switches By : Mia Phillips Float switches are very useful devices, their function is to indicate the liquid level in a reservoir by putting into action an alarm, an indicator or something else.
