A basic soil test usually measures phosphorus, potassium, soil pH and organic matter. A soil test is a chemical analysis that estimates a soil's ability to supply nutrients. pH is tested on a scale of zero to 14, with zero being very acidic and 14 being very alkaline. (Note: no need to test for nitrogen because it moves in and out of soil so quickly that testing would be meaningless). septic truck. 9. Remove one cup of the mixture and submit in a plastic bag. If fall nitrate levels are very high (e.g., greater than about 60 lb N/acre) and soil depth is less than two feet, a second sampling in spring is strongly suggested because there is a higher likelihood of . Place soil sample about full in sample jar and add distilled water to cover soil. Dump the filled scoop into the sample jar with the water and nutrient-absorbing capsule. In J.T. When field moist soil high in K is dried for analysis, soil test K decreases. The quantity of available nutrients in the sample determines the amount of fertilizer that is recommended. Diane Riddle. Windsor Soil Testing Laboratory. Fill the included scoop (level) with the thoroughly-mixed sample. Acidic or alkaline fields are treated correspondingly. Results from a soilt test allow you to monitor soil chemical conditions, tap existing nutrient supplies, identify nutirent deficiencies, and apply optimum fertilizer amounts. Fully saturating the soil before testing will increase the accuracy of this test. (3 pages) Drainage conditions can be controlled, and pore water . 4 Soil test kit ($25-$30): Same as the pH tester, only it adds three extra containers and capsules to measure nitrogen, phosphorus, and potash.

This knowledge will aid in the design and implementation of the correct ground system to meet the particular site requirements. A soil test is a process by which elements (phosphorus, potassium, calcium, magnesium, sodium, sulfur, manganese, copper and zinc) are chemically removed from the soil and measured for their "plant available" content within the sample. Soil pH is measured on a scale of 1 to 14 with a measurement of 7.0 considered neutral. As we all know, soil type and quality vary greatly around the world. For example, pH can be raised with lime, and an accurate pH test helps determine its required quantity. Waters Agricultural Laboratories, Inc. combines the best in equipment, personnel, experience and reputation to provide testing results you can trust. Measurements of total nutrient content are not useful indicators of sufficiency for plant growth, because only a small portion of the nutrients are plant-available. Do not use a metal bucket or rusty spade. Soil Organisms- You don't need to actually handle earthworms for this test, just count them. For the pH test, you add soil, then water, then reagent.

Using a mesh sieve or old colander, sift the soil to remove any debris, rocks, and large organic matter (leaves, sticks, roots, etc.). The results provide a chemical inventory of the soil - clues as to the quantity of nutrients or elements in the soil and their availability for plant growth. Particle Size Using water, soda bottles, and soil, students can use "the bigger they are, the faster they fall" principle to find out whether sand, silt, or clay is made of larger particles. Most plants grow best in soil with a fairly neutral pH, between six and seven. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil.
