| Abstract: |
| Based on the protection of agriculture environmental, quantitative analysis was conducted on the aspects of the total nitrogen of livestock and poultry waste, the losing amount in its processing and utilization, the available soil nitrogen, requirement and using efficiency of nitrogen in agricultural cultivation. And nitrogen balance was taken as index, a new accounting method in carrying capacity of livestock and poultry waste in the base of agricultural cultivation was proposed. In this thesis, Changsha City of Hunan Province as an example, the accurate carrying capacity of the livestock and poultry waste in current agricultural cultivation was calculated by using the method of constructing. Combined with the proportion of chemical fertilizer in this region, the maximum capacity of livestock and poultry breeding in the conditions of current agricultural planting was calculated. |
