摘要
The properties of meadow alluvial soils irrigated with river and wastewaters are described. It is found that the fertility of very stony meadow alluvial soils in sparse grasslands (the projective cover of 35-40%) decreases upon hood irrigation with large amounts of water, especially wastewater. The application of wastewater for irrigation purposes leads to the accumulation of salts (including toxic ones), to sodication, and reduces the content of humus and nitrogen in these soils.
