Soil testing

Basic soil testing analyzes nutrient content and fertility status. Results include fertilizer and lime recommendations. Additional tests are available for nutrient management plans, environmental issues, potting mixes, compost, manure and water usage. Each sample should contain about 1½ cups of dry soil from 6 to 7 inches deep. Consult our soil testing publications for specific instructions. Results are typically provided within two weeks.

Don’t guess, soil tests!  Soil testing saves time and money! Soil testing is the best guide to the wise and efficient use of fertilizer and soil amendments. Whether you grow acres of row crops or have a vegetable patch in the backyard, a soil test will provide you with an analysis of nutrients and a set of recommendations for any improvements. Soil testing can be done through the extension office. When you soil test through our Local Extension Office, your report will also include recommendations from the Agronomist or Horticulturist that serves Wright County.  Please make sure your soil is dry when you bring it in. Fee: $20 per sample. Results in about 7-10 days week. Soil augers are available for loan.
