Samples are analyzed for: % Moisture, Total Nitrogen or TKN, Total Phosphate, Potash, Calcium, Magnesium, Sulfur, and certain micronutrients reported in pounds per 1,000 gallons and as a percentage on a wet basis. Containers, sample forms, and instructions can be obtained from a local Extension Office. Your local Extension agent or DCR nutrient management specialist should  be consulted for interpretation of the results.
