Ammonium Nitrate — Dual-Form Nitrogen for Blending & Direct Use
Ammonium nitrate at 34.4% N delivers half its nitrogen as immediately available nitrate and half as ammonium, making it a versatile base for NPK compound production and direct field application on neutral soils. Granules 1–4 mm flow freely through pneumatic spreaders and bulk-handling systems. Widely used in cereal top-dress, cotton pre-plant and mining explosive manufacturing where regulatory permits allow. Export contracts from 1,000 MT.

Packaging & Shipment
AN moves in bulk vessel holds with anti-caking treatment, or in 50 kg PP bags and 1,000 kg FIBC for markets requiring bagged delivery. Storage must be segregated from combustibles, organic matter and fuel per local explosive precursor regulations. FOB loading at approved fertilizer terminal; CFR/CIF to licensed discharge port. HS 3102.30; COA confirming N fractions and moisture per lot.
FAQ
Why does ammonium nitrate combine both nitrate and ammonium nitrogen?
The 50:50 split gives rapid crop response from nitrate-N while ammonium-N adsorbs to soil colloids and resists leaching. This dual behaviour makes AN effective for single-pass top-dress on sandy loam soils where pure nitrate sources would wash out quickly.
What storage conditions prevent caking in bulk AN?
Maintain moisture below 0.3% at dispatch and store in ventilated warehouses away from heat sources above 40°C. Bulk piles should be turned periodically during long storage; anti-caking agents applied at production extend free-flowing properties through transit.
Can AN be used in NPK compound granulation?
Yes. AN is a primary nitrogen feedstock in compound fertilizer plants, combined with MAP, MOP and fillers to produce customized NPK grades. Its low residual acidity compared to urea simplifies granulation chemistry.
