A study was conducted to determine the mineral nitrogen content (ammonium and nitrate form) of silty soil (pH 4.2) applied with four fertilizers: NPK, NPK + MgSO4 7H2O, NPK + MgO + CaO, and control. The fertilizer rates for test plants (winter wheat, winter rape, and oats) were determined using NAW-2 programme. Ammophoska, ammo-phos-potassium fertilizer, MgSO4, MgO + CaO and top dressing ammonium nitrate were applied.
