An application of the adaptive-landscape agricultural system directed to the durable activity of the natural and agroecosystems is possible by the agroecological evaluation of soils, system analysis, use of the modelling methods. Rational use of the pastures, restoration of the unfit areas and protection intensifying are prinsipal duties standing before the state considering an important role of the pastures in the environment protection and as a fodder base in the cattle-breeding development. The mountain grey-brown soils under pactures of the Gobustan massive in the Azerbaijan Republic were taken as a research object. A total area of the zone is 120970 hectares. The winter pasture areas from them are 76875 hectares. The ecological fertility model consisting of five blocks (ecology, soil composition, soil properties, plant, agromelioration) of the mountain grey-brown soils under pastures in the Gobustan massive was worked out based on N. N. Rosov, D. S. Bulgakov, L. L. Shishov, D. N. Durmanov, I. I. Karmanov’s methodic directions. The ecology block includes climatic and relief indicators of this territory. In blocks of soil composition and properties of gray-brown soils under pastures, data on the particle size and the organic composition of soils, as well as the agrophysical and agrochemical properties of the soils of the studied soils, are collected. The plant block contains geobotanical data on phytocenoses. Using this model together with the methods of rational use of pastures, it is possible to increase the productivity of Gobustan winter pastures and contribute to the development of cattle breeding in this region.
