AgroDex CaB is a commercial liquid fertiliser providing a readily available source of calcium, nitrogen, and boron, supported by organic and amino acids for superior uptake and mobility. Its calcium base is bonded with a specialised organic acid, ensuring efficient chelation and rapid movement within the plant. Formulated to correct and prevent calcium deficiencies, AgroDex CaB supports cell strength, fruit quality, and overall plant development. The inclusion of boron enhances flowering, pollination, and fruit set, making AgroDex CaB a complete solution for improving crop performance in a wide variety of soils and production systems.
AgroDex CaB is primarily used to correct calcium deficiencies while supplying nitrogen for growth and boron for reproductive development. It is suited to fruiting crops, vegetables, nuts, vines, and broadacre systems where calcium mobility is limited but essential for crop yield and quality.
| Calcium (complexed with organic acid) | Highly available |
| Nitrogen | Readily available source for growth |
| Boron | Included for reproductive support |
| Organic Acids | Specialised chelation agent for calcium uptake |
| Amino Acids | Enhances nutrient assimilation |
| Pack Sizes | 5 Litre 20 Litre, 200 Litre, 1000 Litre |
Calcium deficiencies often lead to poor fruit set, blossom end rot, weak cell walls, and reduced crop quality. AgroDex CaB delivers calcium in a highly available, organically complexed form, ensuring efficient uptake even in conditions where calcium mobility is limited. Combined with nitrogen and boron, it provides a balanced nutrient profile that supports both vegetative growth and reproductive development. The result is stronger plants, better fruit quality, and improved yield consistency across a wide variety of crops.
Why is calcium delivered with organic acids more effective for crops?
Standard calcium fertilisers often remain immobile in the soil or plant tissues, limiting their effectiveness. AgroDex CaB uses organic acids to chelate calcium, improving its uptake and movement within the plant. This ensures calcium reaches critical tissues like developing fruits and young leaves. The added nitrogen supports growth, while boron enhances pollination and fruit set, giving crops a complete nutritional boost.
Key benefits include:
This makes AgroDex CaB an advanced solution for managing calcium nutrition in commercial crop production.
INFORMATION SHEET
I have a couple of olive trees with a bark problem. This particular tree is a bit stressed from lace bug I believe, I'm not sure they've had their full care for the last couple of years due to the transition. It needs a bit of a prune too which I will take care of before I spray it. But will wait for your comments first. See image below.
Sunburn can occur in olive trees as damage to bark, foliage, fruit which is caused by excessive solar radiation exposure and seriously affect growth.
Sunburn can cause the tree the olive tree to be more susceptible to borers. Olive trees affected by sunburn are typically poor in health and if severe enough can result in premature death.
Sunburn in olive trees is usually associated with warm weather coupled with water deficit.
Although olive trees are well adapted to hot and dry conditions, too much heat can result in lower yields, leaf wilt, and reduced photosynthesis as the olive tree shuts down critical functions to respond to heat stress.
Older trees can be damaged when the bark is newly exposed to the sun because of pruning or premature leaf drop. Heavy pruning of olive trees can lead to increase reflected light or radiate heat around established trees can also lead to sunburn.
Sunburn to trunks can leave the tissue dried, cracked and sunken and the bark may peel away leaving the wood susceptible for borer attack or fungal infections to enter the bark for further damage to the exposed hardwood underneath.
Foliage may be brown and necrosis begins at leaf tips, margins and between veins.
Heat stress usually results in fruit drop if an olive crop is present.
Encourage good soil health and moisture-holding capacity. Encourage branch structure with proper pruning and plant training. Retain branches that will help to shade the trunk and be beneficial for cropping.
Give trees adequate irrigation to reduce stress and do not overwater trees.
For olive trees and fruit to reduce the risk of sunburn use Kaolin clay applied as a foliar film to help offer protection in reducing heat stress and intense solar radiation.
Whitewashing trunks may help prevent sunburn which is usually seen as an application of rubberised tree sealant. Sometimes water-based paints are used.
If leaves have not already been killed, sunburn injury to foliage can often be remedied by adequate irrigation, adding shade or shelter, and improving soil conditions.
Bark has been affected by intense sun radiation exposure and also water deficit.
