Calcium Ammonium Nitrate (CAN)
Calcium Ammonium Nitrate (CAN) is a high‑efficiency compound fertilizer derived from modified ammonium nitrate. It has become a preferred nutrient source for cash crops worldwide, thanks to its unique combination of nitrogen and calcium in a single, safe, and environmentally friendly granule. By blending ammoniacal nitrogen with nitrate nitrogen in an optimal ratio and adding water‑soluble calcium, CAN not only meets crops' rapid nitrogen demand but also prevents physiological disorders caused by calcium deficiency-such as fruit cracking and blossom‑end rot. The result is a dual gain: higher yields and improved quality.
Agricultural‑grade CAN is developed following the "full nitrate‑based water‑soluble" formulation philosophy. It is manufactured by precisely fusing ammonium nitrate with high‑quality limestone at a scientific ratio of 60:40. The final product guarantees:
- Total nitrogen (N) ≥ 15%
- Calcium oxide (CaO) ≥ 18%
The granules are uniform, exhibit low hygroscopicity, and are resistant to caking-physical characteristics that far exceed industry standards. This makes CAN suitable for a wide range of applications, from greenhouse cultivation to open‑field farming, and particularly effective for calcium‑ and nitrogen‑sensitive cash crops such as fruits, vegetables, tobacco, and potatoes.

Note: 1 mu ≈ 1/15 hectare. For international conversions, adjust accordingly (e.g., 10 kg/mu ≈ 150 kg/ha).
Core Competitive Advantages
Synergistic nutrient efficiency – The balanced nitrogen forms (nitrate + ammoniacal) and readily available calcium work together, boosting nutrient uptake efficiency by up to 30% compared to conventional single-nutrient fertilizers.
Broad adaptability and proven yield/quality improvement – CAN performs consistently across diverse cropping systems and climates. Growers regularly report not only significant yield increases but also better marketable quality-firmer fruits, richer colour, reduced physiological defects, and extended shelf life.
