SAVING TECHNOLOGIES TILLAGE OF SOIL ON DARKLY-CHESTNUT SOILS OF NORTH KAZAKHSTAN

The results of long-term researches on determining efficiency of various technologies of soil cultivation of a spring wheat on darkly-chestnut soils of North Kazakhstan are given in this article. It was studied traditional, minimum and zero technology of the soil cultivation. It is established that at traditional technology of soil cultivation erosion po-tential of the soil is much higher in comparison with the minimum and zero technology of cultivation. Excess of productivity of spring wheat at zero and minimum technology of cultivation in comparison with traditional cultiva-tion was respectively 2,1 and 1,7/hectare
