DAP (Diammonium Phosphate)

Phosphorus-Rich Crop Nutrition

The world's most widely used phosphate fertilizer — a concentrated source of phosphorus with a useful dose of nitrogen, graded 18-46-0.

  • 46%Phosphate (P₂O₅)
  • 18%Nitrogen

Concentrated phosphorus, with a useful dose of nitrogen — graded 18-46-0, the world's go-to phosphate at planting.

Standard 18-46-0 — firm, uniform granules — often weighed against MAP (11-52-0), which is more acidic and higher in phosphate.

Why it matters

Phosphorus drives early root development and energy transfer. DAP's high concentration and good handling make it the default phosphate source across most cropping systems.

Core checks

Nutrient content, granule size and moisture, plus cadmium content, which some import markets regulate.

Establishment

Placed at or before sowing to build strong roots and early vigour.

Blending base

A phosphate base combined with other products into custom NPK programmes.

Standard grade 18-46-0 — 18% N, 46% P₂O₅; often compared with MAP (11-52-0), higher-P and more acidic.
