Description

Topsoil exposed to rainfall when crops are produced on sloping land creates a major environmental problem in the United States. Runoff and the resulting soil erosion carries sediment and agricultural chemicals into public waterways. Besides polluting the waterways, the process also reduces soil productivity. Even with conservation efforts, including the creation of soil conservation [30] and land use laws regulating soil and water conservation, erosion of agricultural topsoil remains a problem and will likely require new and integrated policies set by national agencies.
