DYNAMICS OF PHOSPHATES, VARIOUS SOLUBILITY IN SOD-PODZOLIC LIGHT-LOAMY SOIL WITH VERY HIGH RESOURCES OF PHOSPHORUS
Abstract
The results of studies on the phosphate state of sod-podzolic light loamy soil under conditions of residual aftereffect of phosphorus fertilizers are presented. With a very high supply of soil with phosphates of various solubilities, a significant decrease in the degree of phosphate mobility (by 15-29 %) was noted for mineral and organic backgrounds of the crop rotation. A significant decrease in the phosphate content, determined by the method of Kirsanov and I + II group according to Chirikov, was observed exclusively against a manless background and did not exceed 8 and 5 %, respectively. The change in the amount of phosphates of group III according to Chirikov was insignificant.
