AgroDex K45 is a highly concentrated liquid potassium fertiliser designed for use in fruit and vegetable production, cereal crops, legumes, cotton, nut crops, turf, and berries. It combines 45% potassium with fulvic and organic acids for rapid uptake and efficient translocation in plants. By improving colour, size, and ripening, AgroDex K45 helps crops reach optimum quality during critical growth stages. Its nitrate and chloride-free formulation makes it safe for regular fertigation or foliar use in mid-to-late season programs.
AgroDex K45 is primarily used to enhance fruit and crop quality by improving size, colour, ripening, and finishing. It is especially effective during periods of high potassium demand, such as flowering, fruit fill, and grain filling. Commonly applied in cotton (from squaring to boll fill), nut trees, fruiting vegetables, cucurbits, cereals, and turf.

Potassium is vital for plant health, regulating water balance, stomatal function, and the production of sugars, starches, and proteins. AgroDex K45 supplies potassium in a concentrated liquid form enhanced with organic acids, ensuring efficient uptake. It supports translocation and respiration, improving fruit colour, size, ripening, and overall crop finishing. Suitable for a wide range of crops, AgroDex K45 is a reliable tool for boosting both yield and quality.
What makes AgroDex K45 important for fruit and crop finishing?
AgroDex K45 provides a concentrated source of potassium, a nutrient that drives fruit sizing, colour, and ripening. Potassium also regulates water balance and is essential for photosynthesis and protein synthesis. By combining potassium with organic acids, AgroDex K45 ensures maximum uptake and mobility in plants, making it ideal for critical growth periods such as fruit set, grain fill, and boll fill.
Key benefits include:
This makes AgroDex K45 a valuable input for growers targeting premium crop quality and reliable yields.

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.
