Di-ammonium phosphate (DAP) is a popular fertilizer in agriculture due to its high phosphorus and nitrogen content, which are essential nutrients for plant growth.

1.Phosphorus Source: DAP is a good source of phosphorus, which is important for root development, flowering, and fruiting in plants. Phosphorus also plays a crucial role in energy transfer within the plant.
2.Nitrogen Source: DAP also provides nitrogen, which is essential for plant growth, leaf development, and overall vigor. Nitrogen is a key component of chlorophyll, the pigment that allows plants to photosynthesize.
3.Water Solubility: DAP is water-soluble, making it readily available to plants once applied to the soil. This allows for quick uptake of nutrients by plant roots.
4.PH Neutral: DAP is pH neutral, which means it does not significantly alter the pH of the soil when applied. This makes it suitable for a wide range of soil types.
5.Versatile Application: DAP can be applied to a variety of crops, including grains, fruits, vegetables, and legumes. It is commonly used in both conventional and organic farming practices.
6.Starter Fertilizer: DAP is often used as a starter fertilizer for crops at planting time to provide the initial nutrient boost needed for early growth.
7.Storage: DAP is relatively stable and can be stored for long periods without significant degradation, making it a convenient fertilizer option for farmers.
