The article describes the results of a model experiment on restoration soil fertility on natural substrates. The experiment was carried out on the territory of the Samotlorskoye field. Typically, these natural substrates are used in land reclamation measures. The study area has humid conditions with frozen rocks occurrence. The experiment investigated natural substrates in the form of peat or sand, or mixtures thereof, which are the most commonly used during reclamation. The analysis of the humus qualitative characteristics shows effective humus recovery on reclaimed lands. During the ten-year observation, the carbon deposition by the studied young soils was assessed. These data can be used in the development of car bon projects for green house gas sequestration. Due to the lack of information in the study area about car bon deposition in the phytomass and in the soil in the conditions of oil producing, the relevance of this topic is obvious. In particular, the study of the qualitative characteristics of carbon in soils and substrates, sufficient for reclamation measures, allows us to forma conception of ‘effective soil’. This will reduce the difference in balance between phytomass and carbon dioxide emission in to the atmosphere. The results of the model experiment can become the basis for planning reclamation measures of the Samotlorskoye field lands, which are disturbed by the oil industry, as well as other territories located in humid conditions with frozen rocks occurrence.
