Diammonium phosphate fertilizer DAP 18-46-0

Diammonium Phosphate DAP 18-46-0 fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of Diammonium Phosphate DAP 18-46-0 is the alkaline pH that develops around the dissolving granule.

As ammonium is released from dissolving Diammonium Phosphate DAP 18-46-0 granules, volatile ammonia can be harmful to seedlings and plant roots in immediate proximity. This potential damage is more common when the soil pH is greater than 7, a condition that commonly exists around the dissolving Diammonium Phosphate DAP 18-46-0 granule. To prevent the possibility of seedling damage, care should be taken to avoid placing high concentrations of Diammonium Phosphate DAP 18-46-0 near germinating seeds.

The ammonium present in Diammonium Phosphate DAP 18-46-0 is an excellent N source and will be gradually converted to nitrate by soil bacteria, resulting in a subsequent drop in pH. Therefore, the rise in soil pH surrounding DAP granules is a temporary effect. This initial rise in soil pH neighboring DAP 18-46-0 can influence the micro-site reactions of phosphate and soil organic matter.
