Calcium Ammonium Nitrate

Calcium Ammonium Nitrate (CAN) is a water-soluble nitrogenous fertiliser that is widely used in agriculture to provide plants with a balanced source of nitrogen and calcium. It is produced by combining ammonium nitrate and calcium carbonate, which results in a granular form of fertiliser that dissolves easily in water.

CAN is an excellent source of nitrogen for crops, as it is composed of two forms of nitrogen: ammonium nitrogen and nitrate nitrogen. Ammonium nitrogen is readily available to plants and helps promote vegetative growth, while nitrate nitrogen is more slowly released and supports the growth of flowers and fruits.

The addition of calcium to CAN provides plants with an important nutrient that is essential for strong cell walls and root development. Calcium also helps to improve soil structure and increase nutrient uptake by plants.

CAN is used as a fertiliser for a variety of crops, including vegetables, fruits, grains, and oilseeds. It can be applied as a side dressing or used as a top-dressing to crops, and is typically applied in the early stages of growth or during periods of rapid growth.

Benefits of Calcium Ammonium Nitrate:

  • Provides a balanced source of nitrogen and calcium for plants
  • Promotes healthy root growth and strong stems
  • Increases crop yields and improves overall plant health
  • Can be applied to a variety of crops, including vegetables, fruits, and grains
  • Easy to use and apply


Calcium Ammonium Nitrate is typically applied as a side dressing, broadcast or used as a top-dressing to the crops. The amount of fertiliser to be used will depend on the crop and soil conditions. We recommend consulting with a qualified agronomist to determine the appropriate rate and method of application.
