The results of researches are reflected in relation to the change of indexes of fertility andcellulose activity of soil for till of cereal herbares depending on a fertilizer. Bringing of phosphoric - ofpotassium fertilizers in the dose of P60K90 substantially influenced on the accumulation of dry root massonly at the united bringing them with nitrogen. On a background bringing of N75 the increase of rootmass increased on 0,63 t/ha, and on a background N150 - on 0,63 t/ha. Change of indexes of fertility and cellulose activity of soil for growing of cereal травостоев depending onMost root mass accumulated for bringing of mineral fertilizers in the doses of N150P60K90, and least - in a variant without fertilizers. To phosphorus, in the roots of cereal herbage in a top-soil on the different variants offertilizer from 11 to 17 kg/ha accumulated in limits and, and to potassium - within the limits of 50 - 76 kg/ha.Under operating of the annual bringing on cereal травостой of N75 separately or in combinationwith bringing of P60K90 cellulose activity of soil increased on 4 - 5 for bringing of N150 – 6%.
