Good topsoil is relatively dark in color, active with microorganisms, plant nutrients, and organic matter, and usually has a pH between 5.5 and 7.5 (for non-acid loving plants).
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 for plants that are growing poorly. Perform a soil test every 3 to 4 years.
You can pick up a soil test kit at the Extension Office: 750 Miller Dr., SE, Suite F-3, Leesburg, VA. Instructions are provided.
