Free Soil Testing for Johnson County Residents
“A soil test can save you money on lawn or garden chemicals, and decrease runoff that pollutes our waterways,” Dennis Patton, county horticulture agent, stressed.
Even if you got a free test last year you're eligible for another. Johnson County homeowners are eligible to receive one free test per household per year. Johnson County agriculture producers, which includes pastures, row crops and commercial horticulture, are eligible to receive up to 10 free agriculture soil tests.
It takes 2 – 3 weeks to get the results back from K-State labs so don’t delay. Samples need to be brought or mailed to the Johnson County Extension office at 11811 S. Sunset Drive, Suite 1500, Olathe, KS 66061.
