Abstract:

To combine planting with breeding is an important approach to recycling livestock and poultry manure, preventing and controlling the waste from polluting the environment and reducing the use of chemical fertilizers in farmland. During the period from 2001 to 2013, nitrogen and phosphorus surpluses were found universally in farmlands of Jiangsu Province, and might be divided generally into two phases in intensity, i.e. rising first and then falling. The surplus intensity was commonly higher in the northern part than in the central and southern parts of the province. Excessive input of fertilizer was the main driving factor of the surplus. Compared with the year of 2001, the year of 3013 witnessed a sharp drop in nitrogen and phosphorus surplus intensity in most parts of the province, and great changes took place in budgeting of farmland nitrogen and phosphorus all over the province. Logistic model was used to analyze factors affecting willingness of livestock farms to combine breeding with planting willingness. It was found that subsidies in the name of environmental protection policy, pressure of the supervision of the environmental protection department, breeding scale and supporting land area, etc. are major factors affecting their willingness.

Key words: livestock and poultry farming, balance of nitrogen and phosphorus, planting-breeding combination, willingness, affecting factors
