Combination Measures of Plant Buffer Strips and Agronomic Management to Control Soil and Nutrient Losses of Sloping Land

Abstract:

The combination measures of plant buffer strips with Amorpha fruticosa Linn and 4 different agronomic measures were used to control soil and nutrient losses of sloping land in a small watershed in Danjiangkou Reservoir. The result shows that balanced fertilization, intercrop and ridge, reduced 31.22~40.05×10^-2 kg/hm² and 0.03~1.04×10^-2 kg/hm² respectively, whichever could head off the soil, nitrogen, phosphorus. Compared with the control, hedgerow plots reduced 31.3%, 53.9% of runoff and sediment yield. Thus, those measures played a good role in the prevention of the nutrient, soil and water loss in small watershed
