  • Description: <jats:p>On the eroded sod-podzolic soil of the drive-separated part of the slope in the 3rd rotation of the crop rotation, the consumption of nitrogen fertilizer by herbs increases by 20%, soil nitrogen by 67%, and symbiotic by 23% compared to its lower part. This reduces the immobilization of nitrogen fertilizer, and increase its gaseous losses. Localization of nitrogen fertilizer increases grass consumption of nitrogen fertilizer by 14%, soil nitrogen by 7-10% and symbiotic nitrogen by 26-53% compared to the scattered method of its application. With local application of nitrogen fertilizer grass better (1.1-1.2 times) use nitrogen fertilizer, it is more (1.1-1.2 times) is fixed in the soil and less (1.6-2.6 times) is lost in the form of gaseous compounds compared to the scattered method of its application. This increases the productivity of herbs by 6-11%, the content of raw protein in the phytomass by 0.3-1.1% and reduces the amount of nitrates by 7-16%.</jats:p>
