The article considers development of the technology of recovering disturbed soils intended for nature protection purposes on the territory of Bovanenkovskiy oil, gas and condensate field of Yamal peninsula. In the course of operation, blend composition and consumption rates of seed material were selected, technologies on recultivation sites were established. To perform the research and developmental works on the establishment of the biological recultivation technologies the composition of mixed grass crop, consisting of 5 types of graminaceous plants (poa pratensis, bromopsis inermis, festuca pratensis, festuca rubra, phleum pratense), was developed. Based on the results of establishing technologies on the sites of recultivation, the quality of reclamation works was controlled. It was revealed that the most efficient technology of recultivation of disturbed soils in conditions of Yamal tundra is «Meadow formation» technology. Optimal norms of seeds of perennial grasses are 100-150 kg/ha and those of mineral fertilizer (ammonium nitrate phosphate fertilizer) 150 kg/ha. Following the results of establishing the technologies «Torfomat» and «Recultivite», it was determined that the most promising technology is «Torfomat», whereas «Recultivite» is the least promising.
