Diammonium phosphate, commonly referred to as (DAP 18-46), is the world's most used phosphate fertilizer. As a primary nutrient, DAP helps the plant to capture and convert the sun's energy into useful compounds for the plant. It also stimulates root development and enhances the durability of the stems.
Usage: In addition to its wide usage in the agricultural sector, DAP is also used to impregnate matches, and as a flame-retardant (for fighting forest fires).
* Diammonium Phosphate (DAP) is a highly effective phosphorus and nitrogen fertilizer suitable for a variety of crops and soil types. This product provides essential nutrients that promote vigorous root development, increased crop yield, and enhanced plant resilience.

DAP is the most concentrated phosphate-based fertilizer. It is perfect for any agricultural crop to provide phosphorus nutrition throughout crop growth and development, as well as starter dose of nitrogen and lower sulphur.
It can be applied in autumn for tilling and in spring during sowing, as well as pre sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils. Fertilizer's sulphur also contributes to the better intake of nitrogen and phosphorus by plants.
