NITROGEN BALANCE IN CROP ROTATIONS OF DIFFERENT DESIGN ON ORDINARY CHERNOZEMS OF ROSTOV REGION

Abstract

a slight fluctuation of other their and The of is ordinary medium-power clayey chernozem. The nitrogen balance was calculated in a grain-fallow-raw crop rotation: bare fallow, winter wheat, winter rye, corn for grain, spring barley, peas, winter wheat, maize for silage, winter wheat, sunflower. Fertilizer application system is 7.0 tons of manure + N₄₃Р₃₀K₂₄ per 1 ha, increased system of 11.2 tons of manure + N₆₄Р₄₂K₄₂ 1 ha. the background of manure.
