Зміна показників родючості та целюлозолітична активність ґрунту за вирощування злакових травостоїв

The results of researches are reflected in relation to the change of indexes of fertility and cellulose activity of soil for till of cereal herbares depending on a fertilizer. Bringing of phosphoric - of potassium fertilizers in the dose of P 60 K 90 substantially influenced on the accumulation of dry root mass only at the united bringing them with nitrogen. On a background bringing of N 75 the increase of root mass increased on 0,63 t/ha, and on a background N 150 - on 0,63 t/ha. Change of indexes of fertility and cellulose activity of soil for growing of cereal травостоев depending on Most root mass accumulated for bringing of mineral fertilizers in the doses of N 150 P 60 K 90 , and least - in a variant without fertilizers. To phosphorus, in the roots of cereal травостоя in a top-soil on the different variants of fertilizer 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 N 75 separately or in combination with bringing of P 60 K 90 cellulose activity of soil increased on 4 - 5 for bringing of N 150 – 6%.
