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.
