The properties of soil as a single physical body are largely determined by the composition, correlation, interaction and dynamics of solid, liquid, gaseous and alive phas- es. In this regard, the physical properties of soil play a special role. They include general physical, physicomechanical, water, air, thermal properties, and structure. Physical proper- ties affect the nature of the soil-forming process, soil fertility and plant development. The agronomic properties of the soil, water-air, heat and nutritional regimes, microbiological ac- tivity, and the microclimate over the irrigated area change significantly under the influence of irrigation. The need for land reclamation is determined for each territory by zonal features and specific economic tasks. Maintaining soil moisture in the optimal interval (in the ripe state) contributes to the formation of the structure. The article is aimed at studying the influ- ence of agricultural development of the deposit and irrigation reclamation on the properties of the alluvial meadow soil of Western Transbaikalia. The object of the study is the alluvial meadow soil of Ivolginskaya Depression. The subject of research is changes in the morpho- logical structure and basic physical properties of the soil under the influence of irrigation and cultivation. We have selected deposit as a sample for reference. The properties of the soil have been determined according to the standard methods of soil science.
