Wheat fertilization has its particularities: pay attention to less phosphorus and more potassium
Applying excessive phosphorus to wheat first of all increases costs. This year diammonium phosphate is quite expensive, with the retail price of 64% exceeding 3900 yuan/ton. Phosphorus is essential, but there is no need for excess. Empirical data shows that using 40-50 kg of a ternary compound fertilizer containing 15%-20% pure phosphorus per mu as a base fertilizer generally prevents phosphorus deficiency.
