Calcium Ammonium-Nitrate (CAN)

For pricing please contact your DD Area Manager

CAN contains nitrogen in ammonium and nitric forms. Ammonium nitrogen can be up taken directly by plants but more often is bound to clay particles in the soil where it will over time be nitrified into to nitric nitrogen. Nitric nitrogen moves through soil rapidly and is quickly up taken by plants.

  • N:27%
  • P:0
  • K:0
  • S:0
  • Ca:6%
  • Mg:2%

Why Use CAN?

  • Ammonium and nitric nitrogen require less soil activity to be taken up by plants when compared to urea nitrogen. This means CAN has improved responses when compared to Urea in cooler temperatures when soils are in a more dormant state.
  • Nitrogen losses through ammonium volatilisation are minimal when CAN is applied, meaning CAN can be applied in any weather conditions.
  • CAN contains equal amounts of nitric and ammonium nitrogen offering plants a more consistent supply of fast and slow releasing nitrogen.
  • CAN will not burn seed so is a suitable starter fertiliser as a substitute to DAP and some compound fertilisers when there is a limited/no requirement for phosphate.

When to use

Summer, Autumn, Winter, Spring


Avoid application before large amounts of rainfall (40ml plus within 10 hours) to reduce any leaching.

Nitrogen's Role in Plants

  • Nitrogen is always the nutrient in highest demand by plants, due to the greater content of nitrogen present on a dry weight basis in comparison to any other nutrient.
  • Nitrogen is a primary component of amino acids which are the building blocks of proteins. Thus, by adding nitrogen to soil the protein content in plants is increased.
  • Nitrogen is part of the chlorophyll molecule, and a part of numerous enzymes and coenzymes. Chlorophyll is responsible for photosynthesis, where sunlight is absorbed and stored in the plant as sugars and proteins.
  • Therefore, nitrogen is an integral part of photosynthesis.
  • Signs of nitrogen deficiency – reduced plant growth, yellowing of the leaf, early crop maturing.

Calcium's Role in Plants

  • Calcium is vital for both plant and animal growth
  • An essential part of the plant cell wall and membranes, aiding in plant structure and stability
  • Earthworm activity is increased by the presence of calcium in the soil profile, therefore natural soil aeration is also increased
  • Boosts soil microorganism activity, improving soil structure
  • Calcium deficiency affects fruit crop quality and growth, and limits biological activity
  • Calcium and magnesium work in synergy to promote stable soil structure
  • Involved in the signalling of the availability of other nutrients (e.g. potassium), through its secondary messenger characteristics
  • Assists in protecting the plant from biotic stresses
