Dap vs. Map — What's the Difference?
By Tayyaba Rehman & Maham Liaqat — Updated on April 2, 2024
DAP (Diammonium Phosphate) is a widely used nitrogen and phosphorus fertilizer, while MAP (Monoammonium Phosphate) provides similar nutrients with a different nitrogen content.

Key Differences
DAP is a popular fertilizer combining nitrogen and phosphorus, essential for plant growth, and is highly effective in alkaline soils. Whereas, MAP, also a significant source of nitrogen and phosphorus, is more effective in acidic soils due to its lower ammonia content, making it less volatile.
DAP releases ammonia, which can increase soil pH temporarily, benefiting plants in alkaline soils. On the other hand, MAP's lower ammonia release is preferable for acidic soils, minimizing potential damage to seedlings.
Both DAP and MAP are soluble and quickly available to plants. However, DAP's higher pH effect can influence microbial activity in the soil differently compared to MAP.
In terms of cost-effectiveness, DAP generally offers more nitrogen per pound, making it a preferred choice for many farmers. Meanwhile, MAP's benefits in specific soil conditions can justify its use despite potentially higher costs per unit of nitrogen.
