| Integrated nitrogen fertilizer producers | Ammonium nitrate and nitrate-containing compound fertilizers | Ammonium nitrate commonly contains about 34% nitrogen; specifications vary by product | Convert ammonia and nitric acid into nitrogen fertilizers and supply bulk or downstream fertilizer markets | Production and distribution are subject to strict safety controls because ammonium nitrate presents significant storage, handling, and transport risks |
| Calcium ammonium nitrate manufacturers | Calcium ammonium nitrate (CAN) | Commercial grades commonly contain about 26–27% nitrogen | Supply granular nitrogen fertilizer for agricultural use, often through distributors and regional dealers | Typically made by combining ammonium nitrate with limestone or dolomitic material; exact nutrient and additive specifications differ by grade |
| Specialty fertilizer manufacturers | Potassium nitrate | Common fertilizer grade is approximately 13% nitrogen and 46% K₂O | Serve high-value crops, fertigation, greenhouse production, and other applications requiring both nitrate nitrogen and potassium | Usually marketed as a water-soluble specialty fertilizer; product specifications and packaging depend on the intended application |
| Nitrate salt producers and processors | Sodium nitrate and other nitrate-containing fertilizer materials | Sodium nitrate commonly contains about 16% nitrogen | Supply nitrate products to fertilizer blenders and selected agricultural or industrial markets | Use and marketability depend on product grade, crop requirements, local regulations, and the suitability of sodium-containing inputs for the soil |
| Compound fertilizer producers | Nitrate-containing NPK and mixed fertilizers | Varies by declared N–P₂O₅–K₂O grade | Blend or granulate nitrogen, phosphate, and potash inputs into crop- or region-specific formulations | There is no single standard nutrient analysis; the guaranteed grade on the product label is the relevant specification |
| Distributors and agricultural input dealers | Bagged or bulk nitrate fertilizers from domestic and imported supply channels | Depends on the fertilizer product handled | Connect producers and importers with wholesalers, cooperatives, farms, and commercial growers | Provide regional warehousing, order consolidation, logistics, and product availability; they are part of the supply chain rather than necessarily the manufacturers |
