Some ways of decreasing the expenses of fossil energy on leached chernozyoms of the Krasnoyarsk forest-steppe

Modern production technologies of production of plant growing are based generally on using nonrenewable types of fossil fuel, first of all such as oil and natural gas. One of the ways of energy saving, including fossil, was application of resource-saving (energy saving) technologies of the main processing of the soil of which share was up to 40 % of labor and power expenses. In this regard the influence of various methods of the main processing of the soil on its humidity, contamination and productivity of barley was studied. The researches were conducted on the fields of Krasnoyarsk Research and Development Institute of Agriculture on experimental and production farm "Minino" in 1985-1987 and on training farm "Minderlinskoye" in 2016-2018. The productivity of the barley cultivated on minimum processed soil and without the main processing within three years remained at the level or above control option, except the efficiency of culture in 2018 (the third year) and 2016 (the first year,) respectively. The security of arable horizon of resource-saving technologies of the main processing of the soil with available moisture was good. Developed technological processes in resource-saving technologies were energetically effective, especially in the technology without the main soil processing. The increase of the level of mechanization of technological processes did not significantly affect the productivity of barley and, respectively, the amount of saved-up energy.
