Summary. The paper presents the results of the application developed by the authors of the two approaches to anthropogenic loads. The first approach is based on assessment of the impact of human activity on the stability of soil organic matter, the second is the ratio of the intensity loss of organic matter in soil and the level of compensation of the deficit of the balance of humus. Presents the scale of the anthropogenic load on these indicators. Studies were conducted on deposits and multifactor field STA-transient experience of Unisite (Kursk region, Medvinsky district), founded in 1984 year, perennial grasses, in sertralinum, thermopropionicum crop rotations, devil-replaceable couple on typical Chernozem loam. Found that on deposits and perennial grasses content dehumification organic matter in the soil above 1.7-2.9 times compared with the target rotation and 13-17 with a permanent ferry. In sertralinum the crop in the arable soil layer it accumulates in 1.4 times more than in thermopropionicum. In the standardization study of anthropogenic impacts on the sustainability of soil organic matter revealed favorable anthropogenic load on deposits and perennial grasses, valid in sinatraa by the rotation, the maximum allowable in thermopropionicum crop rotation, and neopost-may – permanent couple. Carried out a rationing of anthropogenic loads on the ratio of experimentally certain intensity loss of organic matter in soil and the level of compensation of the deficit of the balance of humus < 50%. It is revealed that the invalid was on-load, including zeroprobability crop rotation with moldboard treatment in a clean pair on the Northern slope without fertilizer. Valid arohena load installed in sertralinum rotation on all exposures and thermopropionicum – in no-till system processing system on watershed plateau and the southern slope, in other options – og-rancano valid. On the basis of rationing agrogenic loads set the options you require adjustment agrogene load.
