For every 100 kg of maize from the soil to absorb about 2.22-4.24 kg N, the average amount of 2.57 kg; P (p2o5) 1-1.5 kg; potassium (k2o) 1.52-4.00 kg, the average amount of 2.14 kg, higher yield NPK absorbed by sowing.

Maize is very sensitive to nitrogen fertilizer, phosphate fertilizer and manure in the distribution on the basis of in the range of 3-10 kg of urea per acre, 1 kg of urea can yield 6-11 kg of maize. Maize and less phosphorus, but not missing, missing phosphorus-leaf stage, will lead to a future empty stalk baldness. Corn crop is happy zinc, applying zinc fertilizer, an increase of about 15%. Corn fertilization principle is the basis of organic fertilizer, heavy nitrogen, phosphorus fertilizer suitable, increasing potassium fertilizer Fertilizers.
