The cultivated siol nutrient of differend region were collected in 17 township streets offices of Maiji district of Tianshui city . The results showed that the content of organic matter and the total N,total P,total K were 11.35 g/kg,0.76 g/kg,0.78 g/kg and 20.3 g/kg,respectively;the content of available Cu,available N,available P,available K,available Fe,available Zn, available Mn,available B were 1.10 mg/kg,56 mg/kg,13.2 mg/kg,224 mg/kg、8.38 mg/kg,1.12 mg/kg,11.77 mg/kg and 0.29 mg/kg,respectively . The overall evaluation results should be also taken to the content of organic was in the relative lack level available P、Zn、Fe、Mn was in middle level the available B and available N is in deficient level . The content of available K and available Cu is in abundant level、Compared with 1982,there were different degrees of improvement,which available P increase largely,the contents of total K and available K nearly no change .
