Studies were carried out on natural community in Enbekshilder district of Akmola region in 2013-2015.We have investigated pasture performance indicators such as botanical composition, projective cover, and yield of pasture mass.In the prevailing meteorological conditions, the projective cover of plant formation of grass/forb pasture was high, the weight of pasture mass ranged from 1.3 to 2.1 t/ha.The efficiency of fertilization was manifested as early as in the first year of studies, the effectiveness of the joint effect of mineral fertilizers with harrowing during the first year of studies was reduced due to partial drying out of the soil in consequence of soil treatment with BIG-3A drag harrow and John Deer 2600 disk harrow.As a result of fertilizer aftereffect, in the second year of studies, in all variants of mineral fertilizers we observed a high crop yield of green mass in total over two years, especially in the variant with application of nitrogen fertilizer.High total crop yield of green mass in the second year of the study was noted also in the variant with the application of nitrogen-phosphorus fertilizer along with the treatment of sod layer by BIG-3A drag harrow.
