Abstract:
The salt content in 180 samples of concentrated animal manures collected in Jiangsu Province was analyzed and the risk of soil salinisation by the application of manures was evaluated by the methods of spatial analysis on GIS and simulating prediction on the accumulation model of salt in soil. The salt content in animal manures was high, with the highest value of 24.2 g x kg(-1) (dry weight). The risk of potential soil salinisation might exist in the coastal region such as Nantong, Yancheng, Lianyungang and the Xuhuai region such as Xuzhou, Suqian, Huaian with the application of animal manures. There was nearly no risk of salinisation by the application of animal manures on the open-field soil, but was obvious influence on the greenhouse soil, the salt content in the greenhouse soil increased by 1.0-2.5 g x kg(-1) after 65-100 t x (hm2 x a)(-1) dry animal manure with the salt content of 24.2 g x kg(-1) was applied for 2-8 a, which might cause mild, moderate or strong soil salinisation.
