ABSTRACT |
In this research work, the authors, using the recently developed method of fractionating the forms of inorganic phosphorus in calcareous soils, have studied the transformation processes of inorgnic phosphorus in three different phosphate fertilizers, i. e., superphosphate, diammonium phosphate and calcium magnesium phosphate, being commonly used in China, during a period of 3 years after their application to calcareous soils, and based on the experimental results obtained, some problems in current use of phosphate fertilizers are discussed. |
