Analysis Tests Managing manure for optimum economic crop production with minimum environmental impact requires a knowledge of the manure's nutrient content. Instead, manure analysis is recommended for the accurate determination and optimum management of manure nutrients. The Standard Manure Test 1 of this program provides the minimum analysis needed to develop a nutrient management plan. Test results in this package includes total and ammonium nitrogen, total phosphorus, total potassium and percent solids. Standard Manure Test 2 contains all of the analytes in package 1 plus total calcium, magnesium, sulfur copper, zinc, manganese, sodium, iron and aluminum.
Additional analyses are also available.
