Nitrogen fertilizers
Nitrogen is the nutrient crops use in the largest amounts. We supply solid and liquid nitrogen fertilizers for direct application and blending.
Granular urea
The most concentrated solid nitrogen fertilizer, in large, hard granules that suit bulk handling, long-distance shipping and blending.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 46% min |
| Biuret | 1.0% max |
| Moisture | 0.5% max |
| Size | 2–4 mm: 90% min |
Prilled urea
Urea formed into small, smooth prills by spray-cooling, widely used for direct application and in fertilizer blends.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 46% min |
| Biuret | 1.0% max |
| Moisture | 0.5% max |
| Size | 1–2.8 mm: 90% min |
Technical grade urea (TG urea)
High-purity urea with low biuret for industrial use: urea-formaldehyde resins and adhesives for plywood and panels, diesel exhaust fluid, water-soluble fertilizers, animal feed and dyes.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 46% min |
| Biuret | 0.9% max |
| Moisture | 0.5% max |
| Form | Prilled or granular |
Ammonium sulphate (AS)
Supplies nitrogen together with sulphur, which many soils and crops lack. Available as crystals or granules.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 21% min |
| Sulphur (S) | 24% min |
| Form | Crystalline or granular |
Ammonium nitrate (AN)
A fast-acting fertilizer with nitrogen in both nitrate and ammonium forms. Its trade is regulated in many countries.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 34.4% min |
| Size | 1–4 mm: 95% min |
Calcium ammonium nitrate (CAN)
Ammonium nitrate blended with limestone or dolomite. Half the nitrogen is nitrate and half ammonium, and it is safer to handle than straight ammonium nitrate.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 27% |
| Nitrogen forms | Half nitrate, half ammonium |
| Moisture | 1% max |
| Size | 2–5 mm: 95% min |
Ammonium sulphate nitrate (ASN)
Combines nitrate and ammonium nitrogen with sulphur in one granule.
| Typical specification | Value |
|---|---|
| Nitrogen (N) | 26% |
| Sulphur (S) | 13% |
Urea ammonium nitrate solution (UAN)
A liquid nitrogen fertilizer for spraying or fertigation, made from urea and ammonium nitrate dissolved in water.
| Typical specification | Value |
|---|---|
| Grades | UAN 28 and UAN 32 |
| Nitrogen (N) | 28% or 32% |
Solid products are supplied in bulk, in 50 kg bags or in big bags, depending on origin.
Typical specification. The contract specification is agreed with the buyer and confirmed for every shipment.
