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.
