THE EFFECT OF HUMUS ON THE PHYSICAL PROPERTIES OF SOIL AT THE CHATKAL STATE BIOSPHERE RESERVE

Аннотация

The article provides information on the effect of humus on the physical properties (volumetric weight, porosity and mechanical composition) of mountain brown soils-a typical representative of the soils of the Chatkal State Biosphere Reserve. Comparative data on the difference between mountain brown soils of the region and plain soils in terms of texture, specific gravity, bulk density and porosity of other mountain and plain soils are presented. These soils differ from other soils in their special stony, humus, carbonate content, and general physical properties.
