Assessment of the impact of the degrees of degradation of pastures on the desert alluvial meadow soils of the village of Zhambyl

Abstract

   The article considers the features of the structure, chemical composition and physical properties of alluvial meadow soils of the pastures of the desert zone of the village of Zhambyl. These soils were formed in the sandy and sandy alluvial deposits of the Shu River. The soils of the floodplain of the river are mainly characterized by high fertility potential. But one of the factors limiting the growth of their potential fertility is the salinity of the soil image and the degree of degradation of pastures. The assessment of soil and plant indicators of pasture degradation in the Zhambyl base area is given. Previously, the area was irrigated and fertilized, and now it is used as a pasture. But due to overgrazing, the alluvial meadow soils of the desert near the village of Zhambyl and the vegetation on their surface have undergone anthropogenic degradation. Studies have shown that as the degradation of pastures increases, the thickness of the humus layer (A+B1) thinns, and the content of humus and nutrients in the soil decreases. The species and botanical composition of plants is undergoing changes, reducing their protection of the soil surface and the productivity of pasture feed. The results obtained are the theoretical foundations for the development of measures to increase soil fertility and productivity of natural vegetation on degraded pastures in the desert zone.
