Abstract

In conditions of a typical serozem, the influence of the chemical composition and concentration of soil solution on physiological parameters, in particular, on the formation of the leaf surface of the cotton plant, the productivity of photosynthesis and crop yield was studied. Recommendations for the effective use of fertilizers were given. Scientifically grounded fertilizer rates were developed to optimize the concentration of soil solution for plant nutrition.


It is known that the productivity of plants is directly related to the intensity and productivity of physiological and biochemical processes in them. In addition, plant physiology provides a theoretical basis for obtaining high-quality crop yields. The creation of the optimal composition and concentration of soil solution for the mineral nutrition of plants, especially when applying agrotechnical measures, is one of the urgent tasks of great theoretical and practical importance.


The optimum concentration is the most favorable medium for plant development, which helps accelerate the absorption of nutrients by the plants and ensures high crop yields. The regulation of the composition and concentration of the soil solution in the practice of agriculture is carried out by the application of fertilizers, soil cultivation, and land reclamation.


The results obtained are of great theoretical and practical importance in understanding the exchange reactions in the soil-absorbing complex between absorbed ions and ions in the composition of solution; in the effect of fertilizers, irrigation and processing technology on the physiological parameters of plants; in the scientifically grounded application of fertilizers, and in the educational process of higher educational institutions.
