Effect of irrigation and fall moisture reserves on the development of water erosion during snowmelt period
The effect of irrigation and fall moisture reserves on the development of water erosion during snowmelt has been studied. The intensity of snowmelt at the plow was observed to be significantly higher than in the areas protected by the stubble. The flow of snowmelt water was seen only on irrigated soils. The content of suspended sediment in the snowmelt water from plowed land was 14 times higher, with the prevailing easy fraction leading to a greater removal of humus, nutrients and absorbed bases from soil. The depth of soil freezing on arable- and natural grasslands after irrigation (with irrigation norm 1500 m3/ha) in the end of winter was 15 cm higher than on non-irrigated analogues. Refs 17. Figs 3.
