The specific location makes the local environmental issues regionally important. This paper studied arable land area, plantation structure, livestock sector data, which shows that livestock sector contributes a big amount of nitrogen and phosphorus, in terms of the demand from the agriculture use in Jiangsu plain. But actually, there is still much mineral fertiliser used in agriculture, which causes the N and P produced from livestock sector being an important source of pollution to the environment. The paper suggests to tighten up manure management, in order to lead to a big reduction in the pollution to both soil and surface water.展开更多
