For good production of fruits, vegetables and grass, a soil sample test may be needed to determine what needs to be done to improve growing and production.

The form that is below needs to be completed and the sample can be placed in a quart size ziplock bag. We do recommend you double bag it to avoid spillage. Please call 319-337-2145, or email with any questions.
