N removal with yield224,00 kg/ha
Available (soil + prev. crop)30,00 kg/ha
As product
Ammonium nitrate (34.4%)940,00 kg/ha
Urea (46%)703,00 kg/ha
For reference: P₂O₅ removal ≈ 77,00 kg/ha, K₂O ≈ 154,00 kg/ha at this yield.
Balance method: dose = (removal − soil supply − previous crop credit) / use efficiency. N efficiency is typically 50–70%. Confirm with a soil agrochemical analysis.
