The results of the conducted studies revealed that soil erosion agitatedly reduces the humus content. If the reserves of 0-50 cm of the layer are not washed away by mountain- Brown soils - 168 tons per hectare, in a very weakly washed-156t / ha, slightly washedoff 135 tons / ha, medium-washed-108 tons / ha, strongly washed -65 T / ha, and in very strongly washed-32 c / ha. In eroded soils not only reduce the content of common humus, but changes and its qualitative structure, narrows the ratio of carbon to nitrogen, thereby increasing the amount of fulvic acid and reduces the coefficient of mobile forms of humic acids, etc.
