Development of fodder production system based on the optimization of fodder crops species (perennial legumous grasses, maize, cereals, grasses) composition and complex application of intensification means taking into consideration soil moisture regime was realized on the anthropogenically modified peat soils of Polesje region of the Republic of Belarus. In course of investigation the system of the following signs for the formation of the effective structure of fodder crops composition were determined: level of moisture content; level of organic matter content in the tilth-top soil; level of moving forms of phosphorous and potassium and soil pH; correspondence of the conditions of root layer to the morphological peculiar features of the selected crops (water consumption; dry and water periods resistance, response to soil fertility, etc.) . The following criteria for fodder species formation were analysed: yielding capacity of fodder crops; energy intensity for fodder crops cultivation and fodder produced on their basis; economic evaluation of fodder crops cultivation and fodder produced on their basis; amount of ranks; croppage; efficiency of crops cultivation. The discretization of the agricultural areas according to the natural characteristics of soils and their water, chemical and physical properties was proposed. It was recommended to choose the species composition of the fodder crops with the account of the economical characteristics of crops and farm requirements for fodders. The proposed complex approach made it possible to use the reclaimed peat and sandy soil complexes of Polesje
