Calcium Ammonium Nitrate is a widely used, high-performance nitrogen fertilizer, compounded from ammonium nitrate and calcium carbonate or dolomite. It generally comes in white or light grey spherical granules and is fully water-soluble for safe and efficient agricultural application. Calcium Ammonium Nitrate provides both fast-acting and sustained nitrogen nutrition, together with bioavailable calcium for crops. Therefore, it holds an irreplaceable role in modern global crop production and soil health management.

Agricultural Benefits and Nutrient Profile

In modern agriculture, Calcium Ammonium Nitrate is highly favored for its balanced nutrient release characteristics. It contains approximately 27% nitrogen, with nitrate nitrogen and ammonium nitrogen accounting for half each. Nitrate nitrogen can be directly absorbed by crop roots to boost rapid plant growth, while ammonium nitrogen remains in the soil for a longer period to continuously supply nutrients.

In addition, the calcium contained in the product can significantly strengthen crop cell walls, promote root development, and improve fruit quality of high-value crops such as vegetables, fruits and potatoes. Unlike pure ammonium nitrate, which aggravates soil acidification with long-term application, Calcium Ammonium Nitrate is neutral and delivers a mild soil conditioning and calcium-supplementing effect, making it especially suitable for acidic soils.

Safety and Handling Advantages

Besides its excellent agronomic properties, Calcium Ammonium Nitrate is widely recognized for its safety features. Pure ammonium nitrate poses serious fire and explosion risks under certain conditions and is subject to strict restrictions on storage and transportation. By mixing ammonium nitrate with inert limestone or dolomite minerals, manufacturers greatly reduce its explosive hazard. This makes Calcium Ammonium Nitrate much safer for handling, storage and transportation in commercial operations.

Whether it is increasing crop yields, improving crop quality, or ensuring supply chain safety, Calcium Ammonium Nitrate remains a core fertilizer for modern sustainable agriculture.
