| Abstract: | According to greenhouse/screenhouse technique for nutrient survey studies which is provided by Potash and Phosphate Institute of Canada (PPIC),the studies of the nutrient status for Chernozem soil,Chostnut soil,Light chostnut soil and Podzolic calcareous soil,main four farmland soil types in Qinghai,are conducted with laboratory analysis, sorption study and greenhouse basin planting experiment.The results indicated that the method is rapid and accurate to determine the limited factors and evaluate nutrient status of soil. |
