Abstract
One of the main factors that have a direct impact on the crop yield is correct fertilization for achieving an optimal soil composition. The yield, in turn, is one of the main indicators of the agroeconomic substantiation of intra-farmland use projects. There are many factors to consider when choosing a fertilization schedule. These include, in particular, the planned yield, the fore crop previously cultivated on the sown area, the composition of the soil, the region and the crop planned for sowing, etc. A scientifically substantiated solution to such a problem is impossible without the use of economic and mathematical methods and optimization models. Methods of linear optimization have been widely used in land utilization by now. The article proposes an algorithm for calculating the doses of mineral fertilizers, which consists of two stages: calculating the amount of active substance for three main macroelements and directly calculating the dosage of fertilizers applied, based on a linear optimization model.
