Monitoring of Fertilization and Increase of Fertility of Agricultural Soils.

The relevance of the article is that preserving the fertility of lands and improving their quality is one of the pressing problems of today. The purpose of the paper is to build a model for the motorization of fertilization of agricultural soils. Practical and theoretical approaches were used in the study, namely, comparison of the theoretical base with practical results, as well as analysis of the similarities and differences between theoretical and practical results, to form an optimal motorization model with the most successful both in terms of quantity and quality. Within the framework of this paper, approaches to the use of mineral fertilizers for maximum efficiency of plant growth and development are considered. As a result, it was revealed that in the steppe zone there is a close correlation between precipitation and potato yield. The scientific novelty of the study is due to the fact that the dose of mineral fertilizers depends on the supply of nutrients to the soil and many other conditions, but is no less than N90P90K90; for the early yield of most plants, it is enough to add N60P60K60.
