Wind and water erosion lead to a reduction in soil quality and productivity and hence crop yield. However, these effects are difficult to quantify. Topsoil depth is recognized as a major parameter in determining soil quality and productivity. Characterizing topsoil depth-soil productivity relationships is a vital step in assessing the true on-farm costs and benefits of conservation tillage and erosion control programs. If the effect of loss of topsoil (i.e., erosion) on soil productivity could be adequately assessed then figures could be applied to soil erosion costs and the economic benefits of conservation tillage practices.
Several approaches may be used to ...
