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

Nutrient Form:

The Nitrogen in NitroCal K 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.

Potassium is essential for optimal yield, quality and flavour.


Campbells NitroCal K 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 K is ideal as a side-dress application in a fertiliser program or can be used strategically at other specific times in the development of crops, in conjunction with other fertilisers. NitroCal K is designed as a spreadable product.


General rates for horticultural crops as a side-dress are 150 to 200 kg/ha. 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.
