1. Do not mix diammonium phosphate with alkaline fertilizer, otherwise it will cause nitrogen volatilization and reduce the fertilizer efficiency.
2. For crops that have been applied with diammonium phosphate, in the middle and late stages of growth, only a proper amount of nitrogen fertilizer is generally applied, and phosphate fertilizer is no longer needed.
3. In addition to legume crops, most crops should be applied with nitrogen fertilizer directly to adjust the ratio of nitrogen to phosphorus.
