- Аннотация: 20 years after the replacement of bare fallow with a disused land in typical chernozem, the content of the main organogenic elements increased: carbon by 43%, hydrogen by 31%, nitrogen by 25%. At the same time, the recovery of the organic carbon content occurs very slowly, at a rate of about 0.05% per year, which must be taken into account when regulating the humus state of arable soils. The content of the main macronutrients - silicon, aluminum, iron, potassium, sodium, which form the basis of the mineral part of the soil, did not change significantly during this period. At the same time, in the upper part of the profile of the typical chernozem of the disused lands, the content of some mineral elements, actively involved in the biological cycle of matter, increased. This primarily concerns such elements as phosphorus, chromium, lead, sulfur and zinc, to a lesser extent manganese, calcium and magnesium.
