On the basis of the analysis of material of re-search institutions of Siberia the possibility of opti-mization and environmentalization of zone system of processing of the soil in Krasnoyarsk Region is shown. Adaptation of processing of the soil to natu-ral and agroecological conditions, modern level of intensification of production, preservation of envi-ronment is established. The advantage (up to 80 %) dump main processing of the soil on poor cespitose and podsolic and gray forest soils of a subtaiga zone, the balanced application dump (50 %) and resource-saving (50 %) systems of pro-cessing of the soil in a forest-steppe zone and in-crease (to 70-90 %) planing minimum and mulch-ing processing in the open forest-steppe and the steppe is revealed. At the present stage of devel-opment of economy agriculture entered new level of technical and technological development. It is connected with Russia's accession to the World Trade Organization, the increase of the competition in domestic and foreign market, ensuring food in-dependence of the region and financial stability of the enterprises. The packages of agrotechnologies offered production have to predict possible ecologi-cal consequences. Underestimation of traditional and modern systems of soil processing and also mistakes in forecasts, can lead to adverse pro-cesses, destruction of environment. The productivi-ty of grain crops in the world makes 3.1 t/hectare and in the countries of Western Europe it is equal to 6-7 t/hectare and more, and in Krasnoyarsk Re-gion is 2.0-2.3 t/hectare. In the zone section the greatest efficiency of arable land is characteristic for the western group of areas - 2.7 t/hectare, then central - 1.9 t/hectare and east - 1.7 t/hectare. The southern group of areas lag behind in the produc-tivity - 1.4 t/hectare and northern - 1.2 t/hectare.
