Canner gauge tests
Dial-type gauges should be tested annually to ensure accuracy and prevent bacterial contamination of preserved foods. Testing for dial-type pressure canner lids is available by appointment with our nutrition specialist.
Another option is to send your gauge to National Presto for free testing. There is no need to send in the lid. Simply remove the gauge from the cover and send it to:
- National Presto Industries Inc.
- ATTN Gauge Testing
- 3925 N. Hastings Way
- Eau Claire, WI 54703
Presto recommends shipping it with a tracking number for your protection. The carrier is your choice. Please include your mailing address (no P.O. Box) and phone number. Allow about two weeks for it to be returned at no cost to you. For details, call 1-800-877-0441.

Basic soil testing analysis is done by the MU Soil Lab in partnership with our Master Gardeners of Greene County. 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 2 cups of dry soil from 6 to 7 inches deep. Results are typically provided within two weeks.
We recommend bringing at least of pint of soil to our office between 9 a.m. and 4 p.m. Master Gardeners can complete the paperwork and submit your test. One of our extension specialists will review your results. In most cases, gardens, lawns and fields should be tested every two years.
