Physical Description:
CAN contains 27% nitrogen and 8% Calcium as Calcium Carbonate (lime). It consists of dust-free, white free-flowing granules.
Uses:
CAN is commonly used on fruit, process and vegetable crops.
Benefits:
Calcium Ammonium Nitrate can be considered as near-neutral in its effect on soil pH - and therefore can be used on soils that have a low pH without lowering further. This also means it is most suitable for using on perennial fruit crops (where soil incorporation of lime is normally difficult to achieve). CAN is a Nitrogen fertiliser which contains equal parts of fast acting Nitrate-Nitrogen and longer lasting Ammonium-Nitrogen. This ensures a more continuous nitrogen supply to the crop and thus better efficiency of use, and also makes it suitable for unseasonal application during summer or winter.
Application (& Compatibility):
CAN can be applied in base dressings and side dressings, but the actual rates will depend on the farm type, the region and the season. It is most beneficial however when split applied (where possible) on a 4 - 6 weekly basis to ensure a continuous nitrogen supply. CAN is not compatible with Magnesium Oxide nor superphosphate. If mixed with dry lime, it may give off ammonia gas, while mixing with Maxi Super may result in a slush.
Volatilisation of nitrogen from CAN is negligible, therefore the timing of the applications is flexible.
Storage & Handling:
Like most Nitrogen products, CAN absorbs moisture from the atmosphere. It is therefore highly recommended that it is stored either in closed/sealed bags on pallets, or if stored in bulk, covered with a tarp. As with most solid fertilisers, it should also be stored in a cool, dry, well ventilated area.
