Active Ingredient: Diammonium phosphate
Crops: cereals, sugar cane, sowing pastures, dairy pastures, fodder crops and also in horticultural crops; for example, vegetables and tree crops.
It is the source of both phosphorus and nitrogen.
The high phosphorus content makes it a true high analysis fertiliser.
DAP and DAP blends are used on a range of crops in broad-acre farming,
N: P ratio of 1:1 makes it an effective source of nitrogen.
DAP releases free ammonium. Nitrogen in the ammonium form resists leaching and is slower release form of nitrogen.
The free ammonium gives a higher pH reaction immediately around the granule.
The low cost of nitrogen in DAP makes it a cost effective source of nitrogen if Phosphorus is also required.
