Soil Testing Service

The King Conservation District is helping landowners who participate in the Farm Management Program with free basic soil testing, while funds last. Basic soil nutrient testing services are provided to assist with the implementation of Farm Management Plans and soil nutrient management. For each participating landowner, the first soil nutrient test will be free and will include five samples. The District will provide help with subsequent soil sampling, but future lab fees for soil testing will be the responsibility of the landowner.
Soil samples collected as part of this service will be sent to a certified lab to test pH (soil and buffered), nitrate, phosphate, extractable cations (potassium, magnesium, calcium, sodium), organic matter, and cation exchange capacity. Additional tests are available at a fee. The soil testing results are generally available within two to three weeks.

We encourage residents to gather their own soil samples and bring them to our office for processing. Please visit our Soil Sampling Instructions for details.
