REDUCING TOTAL ENERGY COSTS FOR TECHNOLOGICAL OPERATIONS IN AGRICULTURE - A WAY TO REDUCE GREENHOUSE GAS EMISSIONS TO THE ATMOSPHERE
The article is devoted to the search for ways to reduce carbon dioxide emissions into the atmosphere when performing technological operations in agricultural production. It is proposed to calculate the efficiency of using machine and tractor units based on the methods of physical economics, when not a monetary unit is used as an indicator of efficiency, but an energy unit, which is an indirect indicator of saving or increasing emissions of carbon dioxide. It is substantiated that a decrease in total energy costs when performing technological operations for the production of grain and other crops directly leads to a decrease in greenhouse gas emissions into the atmosphere. Examples of computational experiments are given to identify the most optimal brand of a tractor and optimize the parameters of the working width and speed of the seeding machine-tractor unit K-5250 + Agromaster, leading to a decrease in total energy costs and, accordingly, to a decrease in carbon dioxide emissions and carbon sequestration from the air by reducing losses harvest
