Abstract
The article analyzes and evaluates the effectiveness of grain cultivation in Siberia. The high energy intensity and poor execution of technological processes leading to their low efficiency and disturbance of the ecological balance have been revealed. It is necessary to improve the methodological approach and develop new mathematical models for the ecological and economic assessment of technological and technical solutions that reduce energy intensity as the main indicator with the predominant use of extensive technologies and reduce the anthropogenic load on the soil. Methodological and technical and technological solutions are proposed to assess the anthropogenic impact on the environment and reduce material costs in resource-saving technologies for the cultivation of grain crops in Siberia. The main economic indicators of the efficiency of cultivation of agricultural land are considered. The conditions of yield growth as a random variable and the main indicator of agricultural efficiency are shown. The rational structure of the three levels of technology intensity recommended for the conditions of the SFO is determined, and the model of mathematical expectation of full expenditures is substantiated. The functions of useful work and time losses are determined; the ration structure of technological processes of basic tillage is proposed. The prospects of using flexible tillage complexes are considered. For each specific case, an algorithm for the ecological and economic assessment of technological and technical solutions is proposed, taking into account the main economic indicators, including energy supply and the quality of the technological processes performed. To reduce energy intensity and improve the environmental situation, a rational structure of recommended levels of technology intensity for the conditions of the Siberian Federal District with an appropriate set of technical support for basic tillage processes is proposed.
