FEATURES OF SOY MINERAL NUTRITION

Abstract

The purpose of the article is to analyze the features of soybeans for mineral nutrition, the impact of the fertilization system on crop productivity under conditions of climate change. Results. Application of mineral forms of nutrients, especially on poor soils are the main factor in increasing the yield and quality of soybeans. The calculation of the dose of soybean fertilizers should be based on chemical analysis with determination of the content of nutrients in the soil, but not should be less than the removal of power cells. Given the biological capacity of soybeans to consume symbiotic nitrogen and absorb phosphorus from hard-to-reach soil compounds, the use of mineral fertilizers for soy is specific. Macronutrients alone are not enough to realize the potential yield of modern soybean varieties. Soybean plants need micronutrients such as iron (Fe), copper (Cu), molybdenum (Mo), manganese (Mn), cobalt (Co), zinc (Zn), boron (B), and sulfur (S), which are involved in all physiological processes of plant development, increase the efficiency of many enzymes in the plant organism, and improve the absorption of nutrients from the soil by plants. The positive effect of micronutrients is evident in soils with average and, especially, low micronutrient content. One of the important factors that affect the formation and development of soy root nodules and their nitrogen-fixing activity is mineral nitrogen. The application of mineral fertilizers (N30P60K60) with the inoculation of soybean seeds will contribute to the interaction of mineral nitrogen with the natural population of nodule bacteria, a process of photosynthesis that is later implemented in increasing the yield of soybean seeds. Conclusions. A modern effective soybean fertilization system should be aimed at balanced provision of macro and microelements and creation of optimal conditions for nitrogen fixation processes. Bacterization of soybean seeds and application of mineral fertilizers containing macro and microelements N20-40P20-40 K20-40 kg/ha, etc. and N15 in feeding in the budding phase of soybean plants contributes to the effective growth and development of cultivated plants, increasing the yield of soybean seeds.
