Why Soil Test?

Soil testing provides useful information to help people manage their land. A farmer or home gardener might have his/her soil tested to determine how much lime or fertilizer is needed to grow plants and/or avoid over-applying nutrient sources like manure. Parents might test the soil in their yard to see if hazardous amounts of lead or arsenic are present before installing a backyard playset for their children, or before beginning a new vegetable garden. Archeologists use soil testing to learn about past land use at historical sites. Scientists test soil to monitor the effects of new management practices on soil properties and environmental conditions.
