Impact of soil erosion on soil fertility and land productivity

Abstract

Abstract: Studies on the spatial differentiation of soil fertility and land productivity of red soil slope fields under different land use patterns revealed that soil erosion had negative effects on soil fertility and land biological productivity,which mainly manifested in the decreasing contents of soil available N, P, K. and their relative poor on the top and rich at the bottom of the slope, the reduced soil organic matter content, the soil sandification, and the resultant reduction of land biological productivity.

Key words: Red soil slope field, Soil fertility, Land productivity, Spatial differentiation, Soil erosion, plant diversity, altitude, soil moisture and temperature, slope aspect
