Calcium Nitrate + Boron

A top dress fertiliser that provides nitrogen and 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 worldwide 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.


Calcium nitrate + Boron is an ideal fit in most regions, but Calcium Nitrate + Boron 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. 
Calcium Nitrate + Boron can be applied as a band or broadcast application or applied through the fertigation system.  Calcium Nitrate + Boron is suitable for use throughout the duration of the crop, beginning during the very early stages of the season or crop development.

Calcium Nitrate + Boron 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.  General foliar application rates are at a concentration of 1-2%.  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 Calcium Nitrate + Boron distributor or your local agronomist.
