Testing for dial-type pressure canner lids is available. Dial-type gauges should be tested annually to ensure accuracy and prevent bacterial contamination of preserved foods. (Testing is not necessary for weighted gauges.)
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 the Soil and Plant Testing Laboratory website for specific instructions. Results are typically provided within two weeks.
