A top dress fertiliser that provides Nitrogen and Calcium nutrition for vegetables, fruits, vines, flowers, turf and ornamentals.

Nutrient Form:

The Nitrogen in NitroCal is fully available to plants and provides an immediate and predictable growth response. The Calcium helps to reduce plant disorders such as bitter pit of apples, blossom end rot of tomatoes and capsicums, hollow heart of brassica crops, and assists in reducing tip burn of lettuce. Calcium is an essential nutrient for development of all plant tissues and an adequate supply and uptake assures a longer shelf life for all horticultural crops.


Campbells NitroCal cannot be lost to the atmosphere like Urea or Ammonium based fertilisers and:

  • Is not affected by temperature, so nutrients are still available when conditions are cold and wet
  • Does not contain harmful chlorides or heavy metals
  • Is not acidifying to the soil


Campbells NitroCal can be the major Nitrogen source in a fertiliser program or strategically used at specific times in the development of crops, in conjunction with other fertilisers.

NitroCal Greenhouse grade can be applied through the fertigation and also used in hydroponic system. It is particularly suitable as a post harvest application on stone fruit, pome fruit and vines, where it is important to achieve the best flower quality, fruit set and early fruitlet development the following season.


General rates for horticultural crops are between 25 to 70 kg/ha through the fertigation system. When applying NitroCal through the irrigation system more frequent and smaller applications guarantee the nutrients are supplied to the plants without being lost due leaching or excessive rainfall. The actual rates, number of applications and their timing will vary considerably for different crops and for different districts. Before application, seek advice from your Campbell’s distributor or your local agronomist.
