Assessment of the Production of Animal Manure and Its Pollution Potential in Jiangxi Province

There is an increasing concern about the environmental consequences of animal production with the changing of the feeding mode in China.A major concern is about proper disposal and recycle of the nutrients from animal manure.The production of animal manure,the amounts of nitrogen,phosphoreus,CODcr,BOD5 and NH3-N of the manure in Jiangxi Province were analyzed based on the statistical data and literatures.The results indicated that the mean amounts of animal manure,N,P produced were equivalent to 49.19 t,278.77 kg,78.63 kg/hm2 of farm land,respectively in 2006.The amounts of CODcr,BOD5,NH3-N in animal manure were 2.72,2.36,0.26 million tons,respectively.The production was very spatially uneven,suggesting that some areas,such as Ganzhou,Pingxiang and Xinyu,received much higher doses than the mean amounts.
