Products FAQs

Why Use Calcium Ammonium-Nitrate:

CAN has a near neutral effect on PH so is suitable for application when the price of lime application is high.

  • 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 consistent supply of fast release and slow release nitrogen.
  • Ammonium and Nitric Nitrogen require less soil activity to be uptaken 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.

Precautions when applying Calcium Ammonium-Nitrate:

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

Nitrogen's role in crops and pastures:

  • Nitrogen increases the protein content in plants through the vitamins, amino acids and energy systems in which it aids.
  • Nitrogen is necessary for chlorophyll synthesis, the process in which chlorophyll is increased in the plant giving plants a dark green appearance.
  • It is through chlorophyll that sunlight is absorbed as energy into the plant making chlorophyll an important part of photosynthesis where sunlight is absorbed and stored in the plant as sugars and proteins.
  • Hence, Nitrogen is an important part of photosynthesis.

When to use

Winter, Spring

Calcium's role in crops and pastures:

  • Participates in metabolic processes of other nutrients uptake.
  • Promotes proper plant cell elongation.
  • Strengthen cell wall structure – calcium is an essential part of plant cell wall. It forms calcium pectate compounds which give stability to cell walls and bind cells together.
  • Participates in enzymatic and hormonal processes.
  • Helps in protecting the plant against heat stress – calcium improves stomata function and participates in induction of heat shock proteins.
  • Helps in protecting the plant against diseases – numerous fungi and bacteria secret enzymes which impair plant cell wall. Stronger Cell walls, induced by calcium, can avoid the invasion.
  • Affects fruit quality.
  • Has a role in the regulation of the stomata.



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 transformed to nitric nitrogen. Nitric nitrogen moves through soil rapidly and is quickly up taken by plants.
