Abstract:In order to understand the characteristics of soil nutrients in Anguo,a total of 7 900 soil samples were collected to determine nutrients contents by the method of statistics.The results showed that the content of soil organic matter were 14.38 g/kg in Anguo,which turned a rising trend compared with the data from 1980.The nitrogen content was 84.8 mg/kg,which was increased obviously.The contents of available P and available K were increased significantly.In the most areas of Anguo,the contents of micronutrient Fe,Cu,Zn and Mn were above the moderate level.
Keywords:Cultivated land  Soil nutrients  Distribution characteristics
