It is established that in the first four years after a plowing of biomass decrease in productivity of cultivated forage herbs and consumption of elements of food of plants was noted. The shortage of forage for 4 years in comparison with an arable land (control) was (c/hectare dry basis): 16,1-at embedding of reed grass, 29,4 - of willows, 23,2 - of birches, 33,7 - of aspens on not fertilized background, and against NPK, respectively 24,7, 21,3, 15,2 and 3,6.soilfallowreedwillowbirchaspenfertilizerscultivated forage herbsочвазалежьвейникиваберезаосинаудобрениясеяные травы
