Abstract

The AA. studied the physical, chemical, and microbiological processes of soil degradation along a chronosequence of deforestation in the Ziwuling area of northwestern Shaanxi province. The results indicated that soil wet aggregate stability and mean aggregate diameter decreased with years following deforestation. Accelerated erosion resulted in soil nutrient loss, and a decease in soil enzyme activities including notable losses of total soil N, organic C, alkaline phosphatase activity, and invertase activity. The differences in measured parameters between the topsoil and subsoil horizons decreased with time since deforestation, and the AA. concluded that soil erosion was the primary process responsible for the degradation of measured soil physical, chemical, and microbiological properties
