A farmer has 10 ha of land to grow maize. Soil tests show the following available nutrients per hectare: N = 40 kg, P = 15 kg, K = 30 kg. The target levels for optimum yield are N = 120 kg, P = 60 kg, K = 80 kg per hectare. The farmer can use three fertilizers:\n• DAP (diammonium phosphate) containing 18 % N and 46 % P₂O₅ (P₂O₅ is 44 % P).\n• Urea containing 46 % N.\n• MOP (muriate of potash) containing 60 % K₂O (K₂O is 83 % K).\nDetermine the exact amount (in kg per hectare, to two decimal places) of each fertilizer required to meet the nutrient deficits exactly, and give the total fertilizer weight per hectare.
