| Abstract: | Based on 20 parameters obtained from field experiment,animal feeding experimerit and 4 years operation of eco-agricultural business,this paper discusses the source, pool and flux of nitrogen and phosphorus cycling in a combined agro-animal husbandry ecosystem. In order to fit the needs of animal husbandry development in the front Taihang Mountain Plain of North China,introduc-ing legume into high-yielding area to build the entity of eco-agriculture business,is a sound strate-gy for nutrient cycling. It makes the utilization efficiency of mineral N to be 66. 6%and P 63. 3%in the farmland ecosystem, and the recovery of N is 86.6%and P 45.3%in the combined a- gro-animal husbandry ecosystem. |
