Method For Optimization Of Composition And Concentration Of Soil Solution Of Irrigated Soils For Nutrition Of Plants
Abstract
The effect of the chemical composition and concentration of the soil solution of various agrofonds on the nutrient content in cotton of the Namangan-77 variety and its productivity, the changes in the chemical composition and concentration of the soil solution depending on the agricultural background and the season were studied.
As a result of studies, it was found that at a low concentration of soil solution the plant develops poorly, it cannot absorb a sufficient amount of nutrients and, conversely, a high concentration of the solution also negatively affects the plant. The optimal concentration is the most favorable environment for plant development, which helps to accelerate the absorption of nutrients by plants and ensure high crop yields.
The composition and reaction of the soil solution in the practice of agriculture is regulated by the application of fertilizers, soil cultivation, and land reclamation. For example, fertilizers are added to enrich the soil with nutrients, soil cleaning is carried out to eliminate salinization, etc.
The composition of the soil solution, the concentration and ratio of various compounds in it are subject to seasonal variation during the growing season. This is facilitated by the process of plant nutrition. Especially, in the middle of the growing season (July, August), noticeable changes occur in the composition of the soil solution.
The amount of nitrogen, phosphorus and potassium in the organs of cotton depends on environmental conditions. This directly affects the growth, development and productivity of cotton. Therefore, when 300 kg of nitrogen, 210 kg of phosphorus and 150 kg of potassium per hectare are used under the conditions of a typical serozem, optimal conditions for the growth and development of cotton variety Namangana-77 are created. This provides a high yield of cotton.
The results obtained are of great theoretical and practical importance in the knowledge of metabolic reactions in the soil-absorbing complex between the absorbed ions and ions in the solution; the action of fertilizers, irrigation and processing technologies on this process; scientifically sound application of fertilizers, as well as in the educational process of higher educational institutions.
