How should phosphate and potassium fertilizers be applied when growing corn?
How should phosphate and potassium fertilizers be applied when growing corn? Please give guidance. When growing corn, the effect of phosphate and potassium fertilizer application varies greatly depending on the soil's available nutrient content. Increasing phosphate and potassium application helps produce strong seedlings that emerge early, strong plants with large ears, a higher grain-to-leaf ratio, and more grains and greater grain weight; it is an important condition for improving population quality. However, after phosphate and potassium fertilizers are applied, ...
