Urea Phosphate Supplier South Africa

What Is Urea Phosphate?

Urea Phosphate is a water-soluble salt formed by reacting urea with phosphoric acid. It supplies 17% nitrogen and 44% P₂O₅ in a single crystal product. Urea phosphate has an acidifying effect when dissolved, which makes it particularly useful in irrigation systems with high-pH or bicarbonate-rich water, helping to prevent calcium precipitation and maintain phosphate availability in the root zone.

Urea Phosphate in Irrigation Systems

In drip and sprinkler irrigation programs, urea phosphate serves as both a nutrient source and a system maintenance tool. Its acidifying action helps prevent limescale build-up in emitters and pipes when used in alkaline water regions. As a fertilizer, it provides readily available N and P in a single application, reducing the number of products required in a fertigation recipe. It is compatible with most water-soluble fertilizers when properly diluted.
