Soil and Plant Testing Laboratory

The Soil and Plant Testing Laboratory analyzes soil, plant, water, manure, compost and greenhouse media. The fee-based services are available to farmers, homeowners, horticulturists, golf course managers, consultants, researchers and government agencies. The laboratory provides quality testing and unbiased, research-based recommendations to clients for economically viable and environmentally safe nutrient management practices.

The laboratory analyzes about 25,000 to 35,000 field crop (farm) soil samples, 5,000 to 7,000 horticultural crop (lawn and garden) soil samples and 1,000 commercial fruits, vegetables and turf soil samples each year. Soil test reports for samples processed through the laboratory are available online. The test reports can be accessed with a password. Reports are also delivered via U.S. mail and email to regional specialists and clients by request. The regional specialists review and make comments if needed and send the reports to clients.

SoilA properly collected soil sample results in appropriate recommended rates of fertilizer and limestone.
