DAP+ fertilizer is a balanced and available source of phosphorus and nitrogen for plant nutrition. It is highly soluble and dissolves quickly in soil to release phosphate and ammonium. DAP+ provides P nutrition throughout phenological stages of crop development and growth, as well as a starter dose of nitrogen and low sulfur. During dissolution in the soil, it temporarily alkalizes the soil solution, which allows effective use of DAP+ on soils with a pH < 7.0.
