The effectiveness of new forms of granular NPK fertilizers with a coating of granules with a thin film of mixtures of mono- and dicalcium phosphate on sod-podzolic soil in the cultivation of spring wheat is shown. Mono- and dicalcium phosphate in different ratios were used as films protecting against loss of nutrients. The chemical analysis of the crop, the calculation of the removal and the coefficients of the use of nutrients by plants indicated that the NPK fertilizer with a coating of granules with monocalcium phosphate had the greatest efficiency.
