Kevin Shelley, Nutrient and Pest Management Program Specialist
This video demonstrates the recommended procedures for collecting soil samples for basic, field-average fertility analyses from farm fields in Wisconsin. It also discusses procedures for submitting the samples to a state-certified soil testing laboratory. Research-based soil nutrient application recommendations from the University of Wisconsin Extension are based on soil test results. The information provided is useful for managing soil fertility for field crop and processing vegetable production and is consistent with the requirements for nutrient management planning programs in Wisconsin.
