Chemical Specifications
Total Nitrogen (N): 18% minimum, primarily in the ammonium (NH₄) form.
Available Phosphate (P₂O₅): 46% minimum total, with high water solubility (>90% of the
phosphate dissolves easily in moist soil).
Potassium (K₂O): 0%.
Moisture Content: Maximum 1.5% by weight.
pH Value: Typically 7.5 in solution, creating a temporary alkaline reaction around the
granule that transitions to an acidic effect as ammonium is absorbed

​
The 46% phosphorus makes it an ideal fertilizer for promoting root growth, enhancing
energy transfer within the plant, and supporting flowering and fruiting.
Solubility:
DAP 18-46 is highly soluble, meaning it dissolves easily in water and is absorbed quickly by
plants. This ensures that the nutrients are immediately available to plants when needed.
Versatility:
It is suitable for use in a variety of crops, including row crops, perennials, and gardens,
making it a versatile fertilizer.
Improved Root Health:
The phosphorus in DAP is particularly effective in promoting root health and seedling
development, which is key to establishing healthy plants that can thrive throughout the
growing season.

Common Applications:
Row Crops:
Corn, wheat, soybeans, and rice are commonly grown with DAP 18-46, as the fertilizer
promotes strong root systems, which are crucial for these high-demand crops.
Perennial Crops:
Fruit trees, vegetables, and flowers benefit from the high phosphorus content of DAP, which
supports flowering and fruit production.
Home Gardens:
DAP 18-46 is also suitable for use in home gardens to promote root development and overall
plant health.
