Economics of Soil Erosion Control with Application to T Values1

  1. John F. Timmons and
  2. Orley M. Amos Jr.2


Pressure on existing cropland, emanating from a complex set of factors increasing demand for agricultural products and limiting agriculture's production response, is accelerating erosion losses. These losses take place on existing cropland and particularly on cropland converted from noncrop uses. Public concerns regarding effects of increasing soil erosion losses on future productivity of soils and environmental quality of water are being answered with legislation and agency actions to limit soil erosion. These actions require establishment and enforcement of erosion limits of tolerance termed T values.

Establishment and enforcement of T values affect farm income, U.S. capacity to export crops, availability and prices of food for domestic and foreign consumers as well as future soil productivity and quality of water and air. Consequently, all these factors and effects must be considered in establishing particular T values. T values will likely vary due to soil differences and the nature and magnitude of external effects.
