Conceptual forecasting model of increase of winter wheatТs crop yield on indicators of agrochemical characteristics of soil at application of phosphoric fertilizers

A conceptual forecasting model of efficiency of phosphoric fertilizers under winter wheat has been developed. Use of the model allows to choose an optimum phosphorus dose for receipt of potential productivity increase subject to dynamics of all complex of agrochemical properties of soil.
