Abstract
Soil nutrient status is an important indicator of soil fertility,as well as the main basis for scientific fertilization. In this paper,testing soil formula fertilization project in Jiajiang County has been done in 2005.3950 soil samples have been taken in Jiajiang County according to the Ministry of Agriculture standards. The pH value,organic matter,total nitrogen,available nitrogen,phosphorus,potassium six indicators of those soil samples have been tested according to Soil Analysis Technical Specifications standard,then compared with Jiajiang’s second soil survey datas,analyzed the causes of changes in soil nutrients.In finally,formulated the countermeasures,in order to provide the scientific basis for scientific fertilization and soil improvement.关键词
