Granulés de nitrate d'ammonium et de calcium (CAN)

Calcium ammonium nitrate is a safer compound fertilizer improved from ammonium nitrate. By adding limestone or dolomite, it has greatly improved the characteristics of traditional ammonium nitrate such as easy moisture absorption, easy caking and insecurity

• Unique nutrient composition: The product typically provides a total nitrogen content of ≥27%, with nitrate nitrogen (NO₃⁻-N) and ammonium nitrogen (NH₄⁺-N) each accounting for approximately 13.5%. This dual-nitrogen combination ensures that after the fertilizer is applied, nitrate nitrogen can be directly and rapidly absorbed by crops, while ammonium nitrogen can be adsorbed by soil colloids and slowly transformed, providing long-lasting fertilizer efficiency.
• Key trace elements: In addition to the core nitrogen element, calcium ammonium nitrate also contains water-soluble calcium in the form of calcium oxide (CaO), with a content typically ranging from 8% to 12%. Water-soluble calcium can be directly absorbed by the root systems of crops, effectively preventing and correcting various physiological diseases caused by calcium deficiency, such as bitter pit in apples and end rot in tomatoes, etc.
• Outstanding physical and safety properties: Thanks to the addition of calcium carbonate, the product’s hygroscopicity is significantly lower than that of ordinary ammonium nitrate. It has good physical properties, is not prone to caking, and is loose and easy to apply. Meanwhile, it is not classified as a dangerous good and is safer and more reliable in terms of storage and transportation.

The core advantages of the product and the value it brings to you

Efficient and nutritious dual supply, with both quick-acting and long-lasting effects

Crops can simultaneously obtain two forms of nitrogen sources. After fertilization, it can take effect quickly and have a long-lasting effect, meeting the nutritional needs of crops during their critical growth period. The water-soluble calcium it contains can be directly absorbed by crops, strengthening the root system and stems and leaves, and improving the quality and storability of fruits

Improve soil quality and promote sustainable development

This product is a physiologically neutral fertilizer. Long-term application will not cause soil acidification. The calcium ions it contains help improve soil aggregate structure and alleviate soil compaction problems, making it particularly suitable for use in acidic soil.

Safe to use and convenient for storage and transportation

Compared with common ammonium nitrate, calcium ammonium nitrate has lower hygroscopicity, significantly improved caking property, is safer and more stable, and is more convenient for storage and transportation.

It is widely applicable and flexible to apply

The product is 100% water-soluble and can meet the requirements of modern water and fertilizer integration technologies (such as drip irrigation and sprinkler irrigation).It is suitable for base fertilizer, seed fertilizer and top dressing, and can also be directly applied or used to prepare compound fertilizers.

Detailed technical parameters

Main application fields

Calcium ammonium sulfate is widely applicable to various soils and crops, especially performing exceptionally well in the following scenarios:

• Field crops and cash crops: such as wheat, corn, cotton, tobacco, etc., with remarkable effects as top dressing.
• Fruit trees and vegetables: Especially suitable for crops with high calcium requirements such as apples, grapes, citrus fruits, tomatoes, cucumbers, and peppers, it can effectively enhance fruit firmness and quality, and reduce the occurrence of physiological diseases.
• Flowers and facility Agriculture: When applied in greenhouses, it can promote the normal growth of roots, stems and leaves of flowers and vegetables, and ensure the bright color of fruits.
• Acidic soil improvement: Highly suitable for use in acidic soil areas, it can help neutralize soil acidity and improve the soil environment.

Packaging, Storage and Safety Instructions

• Packaging: Commonly available are woven bags of 25kg and 50kg per bag, lined with plastic film for moisture-proofing.
• Storage: It should be stored in a cool, dry and well-ventilated warehouse. Because it is highly hygroscopic, it is necessary to pay attention to moisture prevention.
• Safe Operation: Calcium nitrate is oxidizing. Storage and transportation must be handled as an oxidizing agent. It is recommended to wear appropriate protective equipment during operation, such as dust masks, safety goggles and gloves. Keep away from fire and heat sources, and store separately from reducing agents, flammable materials, acids, etc.
