Soil conservation research have dealt, predominantely, with quantification of soil and water losses assuming that crop yields would be inversely proportional to the increase of erosion. Consequently, information on the erosion's impact on productivity and erodibility as related to exposure of layers of different soil depths to cultivation is scarce. However this information is increasingly important as the concern for preserving the productive potential of soil arise and the need for restoring productivity on degraded lands and its associated costs tend to increase. A greenhouse experiment was conducted in order to detect the effects of simulated erosion through exposure of surface soil and subsoil layers to maize and cowpea growth at varyi...
