Abstract
Based on observed data of soil fertility in Jiangyin City from 1981 to 2011,the effects of traditional fertilization and soil testing and formulated fertilization on soil fertility were analyzed.The results indicated that the traditional method of fertilization not only caused the deficiency of phosphorus and potassium but also the waste of nitrogen fertilizer.After the implementation of soil testing and formulated fertilization in Jiangyin,soil available phosphorus,soil available potassium and soil organic matter increased by 84.5%,45.7% and 6.6% respectively,soil total nitrogen decreased by 5.6%.关键词
