The article presents the results of field studies on the effect of herbicides "STOMP" and "STROBI" and their combined use with mineral fertilizers
on the nitrogen regime of irrigated meadow soil. It was determined that these herbicides with mineral fertilizers had a positive effect on the content of nitrate nitrogen. It has been established that, in connection with the use of herbicides Stomp and Stroba, the growth and development of cotton plants undergo much better conditions.
