AgroDex Mn is a naturally complexed liquid manganese formulation developed to rapidly correct and prevent manganese deficiencies across a wide range of crops and soils. Containing organic acids and amino acids, it offers superior nutrient chelation and translocation, ensuring efficient penetration and absorption by plant tissues. Manganese plays a vital role in plant metabolism and is a key cofactor in photosynthetic and enzymatic processes, helping plants construct carbohydrates essential for energy and growth. AgroDex Mn is suitable for foliar, soil, or fertigation use, providing flexibility for modern crop nutrition programs.

AgroDex Mn provides a balanced and effective solution for managing manganese deficiency, which can otherwise limit photosynthesis, enzyme activation, and plant resilience. Its organic-acid-based chelation system promotes rapid uptake, efficient nutrient transport, and increased activity within plant cells. AgroDex Mn is especially valuable for crops grown in high pH soils or areas with poor manganese availability, improving energy conversion, carbohydrate synthesis, and overall crop health. Regular use ensures optimal growth, leaf colour, and yield performance.
How does AgroDex Mn improve photosynthesis and crop metabolism?
Manganese plays a key role in the photosynthetic machinery of plants. It activates enzymes and catalyzes the breakdown of water molecules during photosynthesis, providing the plant with energy and oxygen. AgroDex Mn supports this process by:
By using AgroDex Mn, growers can strengthen crop metabolism, improve energy production, and maintain consistent yields even in manganese-deficient soils.

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.
