The methodology, structure and major categories of fundamental studies are considered to be carried out within the framework of the Program adopted by the Presidium of Russian Academy of Sciences in accordance with the priority trend in “Depositary functions, technology of indicating the state and risks of soil degradation in the system of planning and rational environment conservation in Russia”. These studies are foreseen to be realized according to 5 projects including digital remote sensing inventory and monitoring of arable lands; transformation, evolution and degradation of soils due to agrogenesis and global climate changes; depositary and ecological functions of soils in agrolandscapes; optimal use of the soil resources; analysis of the soil microbiome index in processes associated with the soil formation, the organic matter transformation and fine regulation of the vegetative process. Theoretically the above program is based upon the available typology and the system of agro-ecological valuation of lands, methodology and projecting of adaptive-land-scape systems in agriculture; the development of the theory of creating and functioning of plant-microbial associations; methods of taxonomic identification of more than 100 soil microbiomes and the theory of soil ecological functions. The methodology under consideration differs from existing approaches by the fact, that the study of soil functions (function groups) is carried out as based upon the statistic and dynamic description of the energy-mass exchange processes at global biosphere levels and services rendered by the soil at the current stage of the human society’s development. A block-scheme of studies and methods has been elaborated. The empiric analysis, physical modeling, imitation of the state in space are used at the depositary level. Biocenotic functions are described on the basis of studying the cycles of transformation, monitoring, metagenome indication, digital inventory and the other up-to-date technologies. The objects, categories, basic trends in transformation, evolution and degradation of soils have been taken into complete account; the adaptation, management and regulation practices have been also determined; the results of scientific and applied studies are expected to be successfully obtained.

Keywords: digital inventory, monitoring, arable lands, soil degradation, climate change, agrolandscape, soil resources, microbiome, organic matter.
