| Summary: | An analysis was made of the variability of the content of available phosphates in the layer of 0-20 cm of low humus southern micellar-carbonate chernozem and the features of their spatial distribution were estimated. Models of the dependence of the yield of winter wheat on the content of available phosphates in the soil and on the dose of mineral phosphorus fertilizers have been developed. The results can be used to calculate spatially differentiated doses of phosphorus fertilizers. |
