Abstract
The purpose. To determine influence of durating agricultural use of technogenic soils, formed of potentially fertile rock formations, upon rates humus accumulation. Methods. Field, laboratory. Results. At long agricultural use of recultivated lands the basic process of pedogenesis is accumulation of humus which speed depends on edaphic characteristics of technogenic soils, bioclimatic potential of terrain, and saturation with phytomelioration agro-ecosystems. Conclusions. The amount and quality of plant residues arriving in technogenic soils is the basic power and matter material for humification and accumulation of humus. The speed-up of processes of accumulation of humus is possible owing to saturation of crop rotations with perennial legume and legume-cereal agro-ecosystems.

Key words: recultivation of lands, technogenic soils, accumulation of humus, phytomelioration.
