AgroDex BORON is a concentrated liquid boron fertiliser designed to rapidly correct boron deficiencies in a wide range of crops. Complexed with organic acids, it delivers superior plant uptake and mobility, ensuring boron reaches the tissues where it is most needed. Boron is essential for cell division, flowering, pollination, seed formation, and fruit set, and it also plays a vital role in calcium uptake and water regulation. AgroDex BORON supports healthier plants, better reproductive growth, and higher quality produce.
AgroDex BORON is used to correct boron deficiencies and promote healthy flowering, pollination, fruit and seed set, and reproductive development. It is suitable for broadacre crops, cotton, vegetables, stonefruit, pome fruit, nuts, olives, grape vines, sub-tropical crops, and turf. It can be applied through both foliar spraying and fertigation systems.

Boron deficiency is one of the most common trace element issues affecting crop yield and quality. AgroDex BORON delivers a highly available source of boron that ensures efficient uptake and mobility within the plant. By supporting reproductive processes, calcium use, and water regulation, AgroDex BORON helps to prevent poor fruit set, flower drop, and misshapen fruit. It is flexible for use in both foliar and fertigation systems, making it a reliable solution for commercial growers across horticultural, broadacre, and turf applications.
What happens to crops when boron deficiency is not corrected?
When crops lack boron, cell division and reproductive processes are impaired. This can result in poor pollination, reduced fruit set, deformed fruit, and weak seed formation. Boron deficiency also limits calcium uptake, leading to weaker plant tissues and reduced water regulation. AgroDex BORON quickly corrects these deficiencies, ensuring healthy flowering, fruiting, and high-quality yields.
Key benefits include:
This makes AgroDex BORON an essential trace element fertiliser for growers aiming to maintain healthy crops and high production.

A successful Grove Management Plan must cover these key areas:
"A grove without an effective irrigation system is unlikely to deliver consistent yields year after year. Many growers still underestimate the water needs of olive trees, and few actually monitor soil moisture levels. This is why so many groves have never achieved a commercial crop." Marcelo Berlanda Specialist Olive Consultant
Water stress negatively affects flowering, fruit set, oil accumulation (oil production), fruit size (table olives), fruit quality, and overall tree health. However, many growers lack a proper system to monitor soil moisture or manage irrigation effectively.
Marcelo recommends:
"Growers should inspect soil moisture weekly during spring and summer, and every two weeks in autumn and winter. Use a shovel to dig at least 400mm under the tree canopy to check moisture. If the soil is hard to dig, it’s too dry – even if the canopy shows no visible signs of stress."
Advanced soil moisture monitoring tools can also provide reliable data on a digital display or computer dashboard.
For optimal grove health, growers must consistently check soil moisture and prevent water stress.
As discussed previously, taking leaf samples is essential to assess your trees’ nutritional status. This information guides the creation of a fertiliser program, a critical component for boosting or maintaining yields.
Typically, no fertiliser is needed in winter, unless you’re addressing soil amendments. However, some groves have severe nutrient deficiencies requiring fertiliser even in winter. Where proper irrigation systems aren’t in place, growers must broadcast fertiliser before rain to allow rainfall to incorporate nutrients into the soil profile, an inefficient use of resources but often the only option.
When applying fertiliser in these conditions, target the area beneath the canopy and, if possible, cultivate the soil to improve incorporation and reduce product loss.
Olives need four essential nutrients: Nitrogen, Phosphorus, Potassium, and Calcium. Check product labels carefully. As a general guideline, aim for:
Avoid pruning during the coldest part of winter and when it’s wet or foggy to reduce the risk of bacterial and fungal disease spread.
The main goals of pruning are to remove dead wood, reduce canopy size, restore tree balance, encourage healthy new growth, and increase fruit set in spring.
Tip: After pruning, apply a copper-based spray to protect wounds from infection by fungi and bacteria.
Pest and disease management is crucial for sustaining yield and tree health. Winter’s colder temperatures reduce insect activity, offering a prime time to tackle pest issues.
Set up a comprehensive Pest and Disease Monitoring Program. During winter, check marked trees (previously affected by pests or diseases) every two weeks; in spring, check weekly. Look under leaves and on new growth for signs like crawlers, yellow spots, black sooty mold, or anything unusual.
Proactive, weekly management is essential for a successful grove.

URGENT FERTILISER SUPPLY UPDATE – MAP & DAP SHORTAGE
This summer cropping season is facing unprecedented challenges in fertiliser supply. Availability of MAP fertiliser (monoammonium phosphate) and DAP fertiliser (diammonium phosphate) is expected to remain extremely limited worldwide, with serious implications for growers planning their nutrient programs.
Since 2021, China has imposed strict quotas and inspection rules on phosphate fertiliser exports to protect domestic prices and safeguard food security.
The impact has been dramatic:
Although Morocco, Russia, the USA, and Saudi Arabia also produce MAP and DAP, they cannot offset the sharp drop in Chinese exports.
The result is:
For olive growers and other professional producers, the impacts are already being felt:
Do not wait for traditional ordering windows. Place orders immediately and consider forward contracting for next season. Securing current pricing now helps protect your operation against higher costs and potential shortages later.
