Changing Parameters of Slope Soil Fertility in the Uimon Hollow in the Republic Altai during the Long Process of Man#s Impact
It is established that long-term man#s impact leads to significant changes in soil properties that determine their fertility. Over the 30 year period there was a significant decrease in the content of physical clay and silt by 10%, humus content and exchangeable potassium, respectively 0,64% and 6,92 mg/100 g. Power of humus horizon and the reaction of the soil solution have no significant changes.
Key words: soil fertility, physical, chemical, physical and chemical properties of soil, man#s impact, grain composition, change in soil properties, water erosion, erosive processes.
