Over-application of phosphate fertilizer causes many harms, do you know these dangers?
1. Apply according to the soil. Soil conditions are closely related to the effectiveness of phosphate fertilizer. On soils with low organic matter and low available phosphorus content, applying phosphate fertilizer to the vast majority of crops can increase yields, therefore, phosphate fertilizer should be allocated mainly to soils with low organic matter content and phosphorus deficiency, so as to give full play to its fertilizer efficiency. Such as red soil dryland, yellow mud field, ...

How can phosphate fertilizer efficiency in wheat fields be improved? Practical methods shared
1. Apply after mixed composting and fermentation with organic fertilizer. Organic fertilizer is rich in organic matter, phosphoric acid and a variety of organic weak acids, which can turn insoluble phosphorus into soluble phosphorus. It not only greatly improves the utilization rate of phosphate fertilizer, but also effectively overcomes the problem of phosphate fertilizer burning seedlings. 2. Apply in combination with nitrogen fertilizer, potassium fertilizer, and zinc fertilizer...
