The paper aimed to emphasize again the problem of degradation of soils used in agriculture. Also, it was studied remediation of deep ploughed soil under steppe vegetation after 30 years of fallow. It was established that investigated arable soil lost 2.12% of humus from 0-25 cm layer or 1.60% from 0-50 cm layer (in comparison with fallow). Besides humus loss, arable soil was depleted in nitrogen and phosphorus. Soil structure of arable soil also underwent changes and became unfavorable for plants growing. It was established that during 30 years of fallow use, the former arable soil partially restored its structure. Humus content of this soils also increased by 0.66% in arable layer 0-25 cm and by 0.57% for layer 0-50 cm (0.02% annually).
