Ecological Analysis Indicators Of Irrigated Gray Pasture Soils

Abstract

The article briefly describes the physical and geographical location of the experiment area. Analyzes of geomorphological, geological and climatic conditions of gray meadow soil formation are given. In the field experiments, standard methods were used for the determination of organic and mineral substances in the soil, and all data were analyzed statistically. The amount of nitrogen in the upper 0-25 cm layer of the soil under the winter grain was 32.51 mg/kg, and in the lower horizon it was 28.47 mg/kg. The amount of nitrogen under cotton is 30.75-26.42 mg/kg, which is probably related to the plant's nitrogen-fixing physiology. The diagnostic indicators of irrigated gray meadow soils and the conditions of ecological reclamation at the same time were analyzed. Recommendations for further use are given.
