Diammonium Phosphate DAP 18-46-0 Agriculrural Use
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.
Management Practices
There are differences in the initial chemical reaction between various commercial P fertilizers in soil, but these dissimilarities become minor over time (within weeks or months) and are minimal as far as plant nutrition is concerned. Most field comparisons between Diammonium Phosphate DAP 18-46-0 and monoammonium phosphate (MAP) show only minor or no differences in plant growth and yield due to P source with proper management.

Non Agricultural Uses
Diammonium Phosphate DAP 18-46-0 is used in many applications as a fire retardant. For example, a mixture of DAP 18-46-0 and other ingredients can be spread in advance of the fire to prevent a forest from burning. It then becomes a nutrient source after the danger of fire has passed. DAP 18-46-0 is used in various industrial processes, such as metal finishing. It is commonly added to wine to sustain yeast fermentation and to cheese to support cheese cultures.
