Maize production - Agricultural Research Council

maize plant is 8,7 g of nitrogen, 5,1 g of phosphorus, and 4,0 g of potassium. Each ton of grain produced removes 15,0 to 18,0 kg of nitrogen, 2,5 to 3,0 kg of phosphorus and 3,0 to 4,0 kg of potassium from the soil. No other crop utilises sunlight more effectively than maize, and its yield per ha is the highest of all grain crops.
