Phosphorus fertilizer utilization rate of 10% -25%, most of the phosphorus is left in the soil, so it has a long aftereffect. According to the study, the annual cumulative application rate of phosphate fertilizers is 5 to 10 years, which is about 50%. Therefore, when phosphate fertilizers are insufficient, after several years of continuous application, they can be re-applied every 2 to 3 years. After using the previously applied phosphate fertilizers, Effectiveness can meet the demand of crops for phosphate fertilizers.
In short, the rational application of phosphate fertilizer, it is necessary to take into account the soil conditions, characteristics of phosphorus fertilizer varieties, crop nutrient characteristics, fertilization methods, but also take into account the rational ratio of nitrogen fertilizer and phosphate fertilizer aftereffect. When the potassium and trace elements in the soil are insufficient, these elements must be fully taken into account so that they do not become the minimum limiting factor. In this way, the fertilizer efficiency of the phosphate fertilizer can be increased.
