Your soil may already have enough nutrients to support plant growth, and you can save time and money as well as helping the environment by not applying more. Using too much fertilizer leads to pest problems and excessive plant growth. It also adds to pollution in Kansas rivers, lakes, streams, and wetlands. Underfertilizing is not the best option either; it can lead to thin grass or weeds which allow soil to erode.

 Soil Testing

The best bet is to have your soil analyzed by a soil testing laboratory to determine if additional nutrients are needed to support plant growth. You can submit soil samples for testing by the Kansas State University Soil Testing Laboratory through your local K-State Research and Extension office (Locate). The KSU Soil Testing Laboratory is a not-for-profit organization that provides high quality analyses of soil.
