We recommend using a soil testing lab because they can test a wider range of nutrients with greater accuracy than a store-bought kit. Soil test results give you baseline information on soil pH, nutrient levels, and organic matter content and recommendations for fertilizing and adjusting soil pH.

Here is our page on soil testing. Select a lab, a basic test, and information on how to take a soil test including a video and instructions. https://extension.umd.edu/hgic/topics/soil-testing-and-soil-testing-labs#taking
