Big reserve of increase in gross collecting of grain and forages are rational use of laylands of droughty steppe agrolandscape regions of the South of Middle Siberia. The purpose is to develop the technology of processing of the deposit in droughty steppe agrolandscape area of the Repub- lic of Khakassia. The researches were conducted in 2012- 2013 on the lands of experimental and production farm "Chernogorskoe" of Ust-Abakan area. The influence of ac- ceptance of the main processing of chestnut low-power medi- um loamy soil of the deposit and glyphosate herbicide on density, humidity, quantity of weed plants and the productivity of oats on green material was studied. The options of the experiment included plowing of the soil, flat processing, disk- ing, cultivation and spraying with herbicide. Soil density in the layer of 10-20 cm when plowing 1.08 g/cm3, processing the soil was one depth of 10-20 cm and 14-16 cm much more - 1.37-1.47 (HCP05 0,15 g/cm3). Before winter the number of weeds at technology with plowing inclusion was less, than at the technologies with minimum soil processing. The quantity of grain units of oats for green material at the technology with using plowing of the deposit made 1.43 t/hectare, at the tech- nologies with minimization of processings was less - on 0.41-t/hectare (HCP05 0.26 t). The costs of funds for diesel fuel at resource-saving processings of chestnut soil of the deposit decreased by 1.5-2.0 times.
