Abstract
Research has established that under the action of various anthropogenic factors that lead to the improvement of grasslands, significant changes occur in the root mass of grasses, as well as in the soil. The accumulation of root mass significantly increased under the action of nitrogen fertilizers in a dose of N60 on the grass herbage. In this case, against the background of the introduction of N60P60K90 compared with the background of P60K90, their dry weight in the 0-20 cm soil layer increased from 11.01 to 12.14 t / ha or by 1.13 t / ha. When applying this dose to alfalfa or alfalfa-grass herbage, the dry weight of roots increased from 10.55-11.30 t / ha to 10.66-11.54 t / ha or by 0.10-0.34 t / ha, which is not reliable.
