Of the quality of the results of the state assessment of soil and landscape objects

An analysis of the current state of agriculture in the Russian Federation has shown that the recently aggravated economic and environmental problems require significant changes in the technologies used towards their biologization and resource conservation while ensuring the profitability of agricultural production. Increasing crop yields can be achieved only with a high culture of agriculture, the introduction of advanced technologies based on the widespread use of various types of organic fertilizers (manure, straw, siderate) and biological plant protection products and growth regulators. This requires in-depth study of the most important zonal aspects of agriculture, one of which is to determine the relationship between soil fertility and crop productivity with systematic fertilization. Therefore, the development of crop cultivation technologies that ensure high and sustainable yields with high quality, excluding the introduction of increased doses of mineral fertilizers, chemical plant protection products, as well as minimal negative effects on the soil is an urgent task of great theoretical and practical importance.
