Standard Manure Test

Managing manure for optimum economic crop production with minimum environmental impact requires a knowledge of the manure's nutrient content. While standardized or "book" values listing average nutrient contents of manures are available, they are of little value because of the large variation that exists among different manure storage and handling systems. Instead, manure analysis is recommended for the accurate determination and optimum management of manure nutrients.

The Agricultural Analytical Services Laboratory is certified for manure testing (since 2009) by the Minnesota Department of Agriculture.

Information on interpreting your manure analysis report and on calculating the appropriate manure application rates for your crops is available in the fact sheet, Using the Penn State Manure Analysis Report (pdf format).

Standard Manure Analysis Tests

The Standard Manure Test 1 of this program provides the minimum analysis needed to develop a nutrient management plan. Test results in this package include 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.
