Principles of Building a Mathematical Model for the Influence of Mineral Fertilizers on Grain Yield

摘要

Approach to the building of grain yield model is considered, depending on the intensity of application of mineral fertilizers. In order to improve the accuracy of the simulation, the system of ordinary Mono differential equations as a general model of the growth of processes' intensity in complex systems is used as the basis. The method of identification of the basic model, the efficiency of which is confirmed experimentally, is proposed. A comparison of the accuracy of the proposed model with known regression analogues is carried out.
