Through a grant provided by Johnson County Stormwater Management, a limited number of free soil tests are available from Johnson County K-State Research and Extension. Knowing the base fertility of soil is important for proper plant growth and is especially important for fall lawn reseeding.
Testing is the only way to know the nutrient levels in soil.
The free tests are good for a routine soil analysis which tests the pH, phosphorus and potassium levels of the soil. Johnson County homeowners are eligible to receive one free test per household. Johnson County agriculture producers, which includes pastures, row crops and commercial horticulture, are eligible to receive up to five free agriculture soil tests
The test is available on a first-come basis. Samples need to be brought or mailed to the Johnson County Extension office at 11811 S. Sunset Drive, Suite 1500, Olathe, KS 66061. To take advantage of this opportunity and learn the specific procedures for collecting a proper sample, or to learn of additional tests that are available for a nominal fee, visit, or call (913) 715-7000.
