Peculiarities of assessment of content of oil products in soils

The permissible content of oil and petroleum products in the soil must have a reasonable regional standard. It should be based on presence of specific and non-specific organic compounds in each specific soil, as well as the natural conditions that cause the ability of the soil to self-cleaning, and its provincial characteristics. The value of concentrations of petroleum products in the soil at a biologically safe level has not been established now. It is impossible to justify the maximum permissible concentration of petroleum products in the soil, since they include compounds that are a necessary component of any soil. We calculated the accumulation coefficient for 106 oil fields in 15 geographical regions of the Russian Federation. The accumulation coefficient varies in a narrow range of 1.19-1.21. It is necessary to compare the results of analysis of contaminated soil with the soil before pollution or with the background to establish the fact of a decrease in soil fertility in pollution. We believe it mandatory to consider the background concentration of petroleum products, which is understood as non-specific organic compounds of soils. The question of rationing of petroleum products in the soil remains open to the present time

Biogeosystem Technique (BGT*) Methodology Will Provide Semiarid Landscape Sustainability (A Case of the South Russia Volgograd Region Soil Resources)

The science and political initiatives focus is not only concerning agricultural intensification for food security and human development. The prevention of land degradation and loss is important, and a new land-use technological platform is needed for human well-being and the ecosystem service coupling. An adverse change in the soil quality of the steppe terrain under the standard agriculture is revealed, and the dynamics of the ecosystem service is assessed. The results indicated that the standard land-use practice deteriorates stability of the soil cover, failing to ensure the soil productivity and the ecosystem services in a dry terrain. For land degradation prevention and soil-environmental services refinement, a new transcendental Biogeosystem Technique (BGT*) technological platform was developed. The BGT* is capable of providing long-term, sustainable land-use management. The BGT* methodology includes intra-soil milling, intra-soil pulse continually discrete watering, and intra-soil waste recycling. The BGT* is a basis for future political initiatives in land-use management to prevent land degradation and loss, to increase soil productivity, and to provide soil-environmental services
