Description
Product Overview
Diammonium Phosphate (DAP) is a high-analysis, highly soluble synthetic fertilizer engineered to deliver immediate and sustained macronutrient support during critical initial crop development phases. Formulated into hard, dust-free granules that flow smoothly through mechanical broadcast spreaders and drill equipment, DAP combines ammoniacal nitrogen with an intensive concentration of phosphorus.
When applied to wet soil, the granules break down rapidly to release plant-ready orthophosphate ions alongside stable ammonium ions. This synergistic combination provides young roots with immediate access to energy building blocks, ensuring strong structural uniformity, excellent canopy flush, and accelerated root anchoring across diverse soil conditions.
Key Performance Benefits
-
Explosive Root Architecture: Packs a heavy 46% phosphorus concentration to drive early tissue division, fuel lateral root branching, and increase root hair density.
-
Synergistic Nutrient Delivery: The presence of ammoniacal nitrogen naturally lowers the micro-pH directly around the dissolving granule, drastically reducing phosphorus fixation in alkaline soils and ensuring optimal absorption.
-
Unmatched Solubility & Dissolution: Engineered to dissolve quickly in contact with basic soil moisture, delivering an immediate nutritional surge right when emerging seedlings or newly transplanted crops require it most.
-
Excellent Handling Characteristics: Highly stable, non-caking, and strictly sorted by granule size to facilitate uniform, pattern-perfect distribution via industrial tractor pull spreaders and automated air seeders.
-
Broad Agricultural Adaptability: Serves as a reliable baseline fertilizer across a massive range of broadacre crops, grains, oilseeds, legumes, and deep-root woody perennial trees.

Industrial Application Rates & Guidelines
DAP application parameters should be adjusted based on localized soil diagnostic testing, crop choice, and targeted seasonal yield projections. For best agronomic results, apply as a pre-plant band placement or incorporate into topsoil zones immediately prior to seeding.
-
Broadacre Grains & Cereals (Wheat, Barley, Oats): 100 to 150 kg per Hectare applied at or just before seeding.
-
Corn & Maize Cultivation: 150 to 250 kg per Hectare applied via targeted side-dress banding to avoid direct seed contact.
-
Legumes & Pulses (Peas, Beans, Soybeans): 100 to 150 kg per Hectare to boost initial nodulation networks.
-
Fruit Orchards & Tree Plantation (At Establishment): 200 to 400 grams per planting hole, thoroughly blended with subsurface soil.
