Any surplus N after a year remains in the soil for the next year (no loss).\n- Fertiliser N costs \(\text{₦}150\) per kg.\n- Market prices are \(\text{₦}250\) per kg of maize and \(\text{₦}180\) per kg of cowpea.\n\nAssuming no other costs, calculate the total net profit over the three‑year cycle per hectare.
