Analysis: 15.5% Nitrogen, 19.3% Calcium, 0.2% Boron

Bag Size: 25kg, 1200kg

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


The addition of Boron in Calcium nitrate provides another essential nutrient, required for quality in horticultural crops. Boron deficiency is the most common nutrient disorder globally, and can reduce crop yields because of poor flowering and fruit set or poor growth.

The need for Boron in flowering crops is highest during flowering as it is involved in the growth of pollen tubes and when fruit are set, due to the high boron content in reproductive organs.


Campbells NitroCal+B is an ideal fit in most regions, but especially in soils with a higher pH or in sandy soils or in high rainfall areas, where Boron is in more limited supply. NitroCal+B can be applied as a band or broadcast application or applied through the fertigation system and is suitable for use throughout the duration of the crop, beginning during the very early stages of the season or crop development.

NitroCal+B is also used 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 dry spread rates for horticultural crops are between 80 to 250 kg/ha as a spread application and between 25 to 70 kg/ha through fertigation. 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.
