Sampling Dairy Manure and Compost for Nutrient Analysis

PNW0673

December 31, 2014

Testing the nutrient content of dairy manure or compost reveals nutrient value and determines the application rate, but it must be done correctly. This six-page guide shows you how to conduct a proper test, from obtaining a representative sample (summarized in a handy two-page, illustrated section), selecting a reliable testing laboratory, determining which lab analyses are needed (including total nitrogen, nitrate nitrogen, ammonium nitrogen, total phosphorus, total potassium and solids) to estimating nutrient availability and calculating all the results.
