SOILS OF THE AGRICULTURAL ZONE OF JALAL-ABAD REGION AND WAYS OF THEIR IMPROVEMENT

The land fund of the agricultural zone of the Jalal-Abad region is mainly composed of light gray soils, typical gray soils, dark gray soils and hydromorphic soils (meadow-gray and meadow soils). Over the past 35-40 years, no comprehensive studies have been conducted on these soils. Analysis of the data obtained shows that the nitrogen, phosphorus and potassium content in these soils is insufficient. In order to stabilize and gradually improve the soil fertility of the region, comprehensive scientific research of the soil cover, scientifically based, painstaking, long-term and rational work of all stakeholders in the agricultural sector of the republic is necessary. Currently, the condition of the soil cover is not comforting. This is our first attempt to analyze the fertility of the soil cover of the region and ways to increase it with the use of organic and natural fertilizers and obtain environmentally friendly and safe food products. Manure and other organic fertilizers have a multifaceted effect on the most important agronomic properties of the soil and, if used correctly, dramatically increase crop yields. These fertilizers primarily serve as a source of nutrients for plants. With manure, all the macro- and microelements necessary for plants enter the soil. Therefore, such fertilizers are called complete. In agriculture, the role of silicon is often underestimated. Meanwhile, our experiments and a large number of scientific facts indicate that mobile silicon plays an important role in increasing soil fertility, growth and development of agricultural crops
