DAP Fertilizer Overview and Pricing in Kenya

Diammonium fertilizer represents a crucial source of N and phosphorus for agricultural production.

NPK Ratio

The typical DAP bag contains 18.0% nitrogen, 46.0% phosphorus pentoxide and 0% potassium, often expressed here as 18‑46‑0 (NPK).

Pricing Trends

In 2024 the typical price for a 50 kg of DAP in Kenya ranges from KES 7000 to KES 8500, based on vendor and location.

A kilogram pack is priced around KES 140, providing a budget‑friendly option for small growers.

Usage

• Onion farms benefit from enhanced bulb development.
• Maize fields obtain robust stalk growth.
• Amaranthus and groundnut crops show higher yield.
• Coffea arabica plantations use DAP in the early growth stage for root system vigor.

Pros

Rapid nitrogen release supports vegetative growth, while phosphorus stimulates root development and flower initiation. Its water‑soluble nature allows easy integration with irrigation systems.

Disadvantages

Over‑application can result in soil alkalinity increase, possibly affecting acid‑loving crops. Incorrect timing may cause nutrient leaching during heavy rains.

Where to Find

Check the HS code 210690 and batch number for genuine before purchase. Local agro‑dealers, e‑commerce platforms, and agri‑store outlets provide DAP with weights ranging from 25 kg.
