Hot Selling High Quality Diammonium Phosphate (DAP)
Diammonium Phosphate (DAP) is one of the most widely used and effective fertilizers in global agriculture. It delivers two essential macronutrients — nitrogen (N) and phosphorus (P) — that are critical for healthy plant development from germination through to harvest.Bulk Diammonium Phosphate DAP Wholesale Supplier
Powerful root development
The high phosphorus content (46% P₂O₅) promotes strong, extensive root systems — enabling crops to access water and nutrients more efficiently throughout the growing season. Particularly effective when applied at planting time. Bulk Diammonium Phosphate DAP Wholesale Supplier
Dual nutrient delivery in one product
DAP supplies both nitrogen and phosphorus — the two nutrients most commonly deficient in agricultural soils worldwide — in a single, easy-to-apply granular product. This simplifies fertilizer programs and reduces the number of products needed. Diammonium Phosphate DAP Wholesale
High water solubility — fast plant uptake
DAP dissolves rapidly in soil water, making nitrogen and phosphorus immediately available to plant roots. This fast-acting nature makes it ideal for pre-plant applications and fertigation systems where quick crop response is required. Bulk Diammonium Phosphate DAP Wholesale Supplier
Promotes flowering and fruit set
Phosphorus is essential for flowering, fruit setting, and seed formation — making DAP particularly valuable for fruits, vegetables, legumes, and oilseed crops where reproductive growth and marketable yield quality are priorities. Diammonium Phosphate DAP Wholesale
Improves crop quality and yield
The combined nitrogen-phosphorus action supports healthy early-season growth, improves crop stands, increases tillering in cereals, and ultimately raises both the quantity and quality of the final harvest across all major crop types.
Suitable for acidic soil pH correction
DAP has a slightly alkaline reaction in soil solution (pH 7.5–8.5), making it beneficial for use in acidic soils where pH correction is needed. It helps improve nutrient availability in soils with pH below the optimal range for most crops.Diammonium Phosphate DAP Wholesale
DAP vs. Other Phosphate Fertilizers
| Fertilizer | N% | P₂O₅% | K% | Best for |
|---|---|---|---|---|
| DAP 18-46-0 | 18% | 46% ✓ | 0% | Pre-plant, all crops |
| MAP 12-61-0 | 12% | 61% | 0% | High-P soils |
| SSP 0-20-0 | 0% | 20% | 0% | Low-cost P source |

Why DAP outperforms for pre-planting?
DAP combines the highest commercially available P₂O₅ content (46%) with a significant nitrogen boost (18%) in a single product. No separate nitrogen application is needed at planting — saving time, logistics cost, and labour. Diammonium Phosphate DAP Wholesale
Agricultural Grade Fertilizer Diammonium Phosphate DAP
Best practices for applying Diammonium Phosphate across different cropping systems, application methods, and soil types for maximum phosphorus and nitrogen use efficiency. Diammonium Phosphate DAP Wholesale
Pre-planting broadcast
Broadcast DAP evenly over the field before tillage and incorporate into the soil 10–15 cm deep. This is the most common method — ensures phosphorus is in the root zone from germination. Apply 2–4 weeks before planting for best results. Diammonium Phosphate DAP Wholesale
Seed-row banding
Place DAP in bands 5 cm below and to the side of the seed row (2×2 placement). Concentrates phosphorus near emerging roots for rapid uptake. Reduces the total DAP needed per hectare versus broadcast application. Diammonium Phosphate DAP Wholesale
Fertigation (dissolve & inject)
Dissolve DAP in water and inject through drip or sprinkler irrigation systems. High water solubility ensures complete dissolution. Provides precise, timing-controlled delivery of nitrogen and phosphorus directly to the root zone.
Vegetable & fruit crops
Apply DAP before transplanting vegetables or at the start of the growing season for fruits. Phosphorus drives early root establishment, improves transplant survival, and accelerates time to first harvest in fast-growing crops.
Cereals — rice and wheat
For paddy rice: apply DAP as a basal dressing before transplanting. For wheat: apply at seeding time or as an early top-dressing. Phosphorus is particularly critical during early tillering when root systems are establishing. Diammonium Phosphate DAP Wholesale
Starter fertilizer
DAP is widely used as a starter fertilizer — a small, concentrated dose placed near the seed at planting. Even small amounts (50–100 kg/ha) of DAP as starter produce measurable improvements in crop establishment and early-season growth.
⚠️ Important application notes
Do not apply DAP in direct contact with seeds in high quantities — the ammonia released during dissolution can damage germinating seedlings. Maintain at least 3–5 cm separation when banding near seeds. In alkaline soils (pH above 7.5), phosphorus from DAP may become less available due to calcium phosphate fixation — consider acidifying the soil or using MAP (more acidic) instead. Do not mix DAP with calcium nitrate or urea in the same solution for liquid application — precipitation may occur. Diammonium Phosphate DAP Wholesale
💡 Maximising phosphorus efficiency
Phosphorus moves very little in soil — it stays where it is placed. For maximum efficiency, incorporate DAP into the root zone rather than leaving it on the soil surface. In high-fixing soils (high clay, high iron/aluminium content), banding DAP is far more efficient than broadcasting because it reduces the soil surface contact that causes fixation. Soil testing before application will confirm whether phosphorus is the limiting nutrient — and at what rate DAP should be applied to achieve the target yield. Diammonium Phosphate DAP Wholesale
Beyond Agriculture — Industrial Uses of DAP
Diammonium Phosphate and its active component ammonium dihydrogen phosphate (NH₄H₂PO₄) have a wide range of applications across multiple industries beyond fertilizer use.
Agriculture
Primary use — as a complex N-P fertilizer for vegetables, fruits, rice, wheat, and all major commercial crops. Pre-plant and starter applications.
Food industry
Used as a flour conditioner and yeast nutrient in baking. Improves dough texture, elasticity, and fermentation performance. Also used in baking powder production.
Brewing & fermentation
Widely used in beer, wine, and yeast production to adjust pH and supply nutrients that support vigorous fermentation. Helps maintain consistent flavour profiles.
Pharmaceuticals
Used as a drug additive in the production of antibiotics including cephalosporins, penicillins, and tetracyclines. Serves as a buffer and nutrient in fermentation media. Diammonium Phosphate DAP Wholesale
Biotechnology
Ammonium dihydrogen phosphate is used to prepare buffers for DNA amplification (PCR) and other molecular biology procedures requiring precise pH control. Diammonium Phosphate DAP Wholesale
Electroplating & welding
Applied in electroplating and welding processes to create protective oxide films on metal surfaces, preventing oxidation and improving surface quality and durability.
Insecticides
Ammonium dihydrogen phosphate serves as a key ingredient in various agricultural insecticides, particularly as a bait attractant for pest control in commercial farming. Diammonium Phosphate DAP Wholesale
Acid soil regulation
Used to adjust pH in acidic soils for improved nutrient availability and plant growth. Also used in horticulture to modify growing media pH for sensitive crops. Diammonium Phosphate DAP Wholesale
