Abstract

Environmental pollution due to livestock breeding with organic manure input instead of chemical fertilizers (partially or completely) has become a major concern. This study conducted six combinations of pig manure treatments (25, 50, 100, 200, 400 and 800 kg P hm-2) with half of conventional chemical fertilizers, conventional fertilization (CF) and an unfertilized control (CK) to investigate the impact of different manure applications on nutrient accumulation and leaching in a peanut-radish cropping system using three soils in subtropical China. The results indicated that a higher application rate of pig manure readily led to excessive phosphorus accumulation in soils and polluted shallow groundwater by nitrate leaching. The leaching risk in the three soils decreased in the following order: granite>sandstone>red clay, and the degree of nutrient accumulation increased in the following order: granite
