Diammonium fertilizer is a crucial source of nitrogen and phosphorus for crop production.
NPK Ratio
A typical DAP bag contains 18% nitrogen, 46% phosphorus pentoxide and 0.0% potassium, often expressed as 18‑46‑0 (NPK).
Current Prices
As of 2025 the standard price for a 50 kg of DAP in Kenya ranges from KES 6,500 read more to KES 8,500, based on dealer and region.
A kilogram pack is priced around KES 130, providing a budget‑friendly option for home garden growers.
Applications
- Allium cepa farms gain from improved bulb development.
- Maize fields obtain robust stalk growth.
- Amaranthus and groundnut crops show higher productivity.
- Coffee plantations apply DAP during early growth stage for root system vigor.
Advantages
Rapid nitrogen release supports vegetative growth, while phosphorus stimulates root development and flower initiation. Its water‑soluble nature enables easy integration with irrigation systems.
Limitations
Excessive use can result in soil alkalinity increase, possibly affecting acid‑loving crops. Incorrect timing can cause nutrient leaching during heavy rains.
How to Purchase
Check the HS code 210690 and batch number for authenticity before purchase. Regional agro‑dealers, e‑commerce platforms, and agri‑store outlets provide DAP in weights ranging from 10 kg.
