A soil test can provide information on the proper amount of lime and fertilizer to apply to your lawn, garden and other areas of your landscape. When gardeners apply only as much lime and fertilizer as is necessary and at the appropriate time, nutrient runoff into surface or ground water is minimized, money is saved, and plant health is optimized. Soil testing can also be used to diagnose common nutrient deficiencies or toxicities for plants that are growing poorly.
The reliability of the soil test, however, can be no better than the sample you submit. For results you can depend on, it is vitally important that you take samples correctly to accurately represent the soil in your landscape.
This web site explains how to obtain representative soil samples and to submit them for analysis to a Soil Testing Laboratory. It is an easy-to-learn process that will benefit you, your landscape and the environment. There are six sections of information (listed below in the table of contents).

Or, you can jump to a particular section by clicking any of the items in the table of contents.
