It is made from two common constituents in the fertilizer industry and it is popular because of its relatively high nutrient content and its excellent physical properties.

It is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of DAP agriculturefertilizer is the alkaline pH that develops around the dissolving granule.As ammonium is released from dissolvingDAPgranular, 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 DAP agriculture fertilizer. To prevent the possibility of seedling damage, care should be taken to avoid placing high concentrations of DAP granular fertilizer near germinating seeds.The ammonium present inDAPagriculture fertilizer 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 granular fertilizeris a temporary effect. This initial rise in soil pH neighboring DAPgranularcan influence the micro-site reactions of phosphate and soil organic matter. Management PracticesThere 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 betweenDAP and monoammonium phosphate (MAP) show only minor or no differences in plant growth and yield due to P source with proper management.
