Erosion processes on chernozyoms of forest-steppe zone of Krasnoyarsk region

Erosion is one of the main negative processes leading to severe degradation of the soil cover. Modern water erosion occurs everywhere, with the combination of anthropogenic, natural and climatic conditions. According to the inventory of farm land in Russian Federation, about 50 % of arable land is subject to water and wind erosion. In the European part of Russia, the area of eroded land is more than6.8 million hectares, or a quarter of arable land. The areas of eroded soil annually increase by an average of 0.36 % of the total area of arable land, and in some regions it reaches 1-1.5 %. Erosion processes not only destroy the soil structure, worsen water and physical properties of the soil, but also contribute to the removal of the main plant nutrients. The researchers studied the transformation of eroded soil properties, humus content and food regime, reducing crop yields, and developed and tested potential soil washout and drainage, agrotechnical and agromeliorative measures to reduce erosion processes...
