| Abstract: | By the phosthorus balance method in a closed system, this paper dealt with the discharge of phosphorus from agricultural non- point source in Taihu-Lake region in southern Jiangsu Province, and the measures to reduce this discharge. The results showed that the total discharge of phosphorus from the surface drainage of farmland in Taihu-Lake region was 440. 4 t/a in a raing year as 1987, and 299. 9 t/a in a dry year as 1988. |
