UAN 30 — Mid-Grade Liquid Nitrogen Solution
At 30% total nitrogen, this urea-ammonium nitrate solution sits between standard 28% farm-grade and high-analysis 32% industrial blends. The 9% urea-N, 8% ammonium-N and 13% nitrate-N profile suits spring top-dress on cereals and continuous fertigation in protected horticulture. Density 1.30 g/cm³ allows slightly higher nitrogen delivery per tank fill compared to UAN 28. Export lots from 1,000 MT via ISO tank, bulk tanker or bagged concentrate.

Application Notes
UAN 30 works well as a split-application nitrogen source — first pass at tillering, second at stem elongation for wheat and barley. In drip systems, maintain solution pH between 6.0 and 7.0 to prevent emitter clogging from phosphate precipitation. Shipments in dedicated stainless or coated carbon steel ISO tanks; each lot with COA confirming nitrogen fractions and density. HS 3102.80.
FAQ
How does UAN 30 differ from UAN 28 in field performance?
UAN 30 delivers 2 percentage points more total nitrogen per litre, reducing tank refill frequency on large pivot systems. The higher urea fraction (9% vs 7%) extends the residual nitrogen supply slightly longer after application.
Is UAN 30 compatible with herbicide tank mixes?
UAN 30 is commonly used as a spray carrier for post-emergence herbicides in cereal crops. Always follow herbicide label rates for carrier volume and perform a jar test — avoid mixing with sulfonylurea herbicides at high UAN concentrations without compatibility testing.
What tank materials are approved for UAN 30 storage?
316 stainless steel, fiberglass-reinforced plastic and coated carbon steel tanks are suitable for long-term UAN 30 storage. Avoid uncoated mild steel — the solution is mildly corrosive and will degrade tank integrity over time.
