With a statewide "Stay at Home" order in place, we will remain closed to the public until April 8, 2020. This means that we are not accepting any soil samples for testing at this time. Posted April 2, 2020
We offer low-cost soil tests to the public for urban landowners (lawn & garden) and small acre farms. The Lawn and Garden Test includes phosphorous, nitrogen, potassium, pH, and organic matter; the Small Farms test also includes sulfur.
