Technical methods for phosphorus and potassium fertilizer management for high-yield maize
The effect of applying phosphorus and potassium fertilizers varies greatly depending on the soil's available nutrient content. Increasing the application of phosphorus and potassium 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, and is an important condition for improving population quality. However, after phosphorus and potassium fertilizers are applied, most are absorbed and fixed by the soil, the absorption and utilization rate in the current season is low, and in the soil...
