The latest chelation system improves crop nutrient uptake

Chelated trace element applications are critical to maximise winter crop yield and it’s important to know how to get the best return on your investment in foliar applied nutrients.

The latest development in trace elements was launched by Omnia Specialities in 2020 and last year demand exceeded production capacity.  With a recent production capacity upgrade, Omnia is confident it can match demand for the upcoming autumn, winter and spring markets, for both horticulture and broadacre.

The new OmniSure® range of trace elements was developed using the latest chelation system, which is unique to Omnia. It has significant advantages over EDTA chelates and ordinary sulphate salts of trace elements.  The chelation system mimics the behaviour of natural organic substances in the plant’s translocation system which means faster uptake and less crop damage. It is highly recommended for foliar applications but has the flexibility to suit soil application also.

Omnia Sales and Marketing Manager, Darren Thomas said, “Older chelation technology like EDTA is OK but some research has shown the EDTA chelate can bioaccumulate in the soil and in the plant itself leading to some plant toxicity which can manifest visually as leaf necrosis. Our novel chelation system mimics the way metal elements are transported in plants by mother nature, this is expressed through faster and more efficient uptake and less crop damage than older systems.”

Picture illustrates how OmniSureCop outperformed EDTA copper regarding crop damage in wheat trial when mixed with the fungicide propiconazole.

Experienced growers know that once you can see trace element deficiency symptoms in your crop, yield potential has already been lost.  Sap testing at key crop stages is the most efficient way to monitor plant nutrient levels so that necessary adjustments can be made.  A crop with a balanced nutrient profile in the sap is more likely to deliver better yield and quality at harvest.

Trace elements applied to the soil with planting fertiliser can be rendered unavailable to the plant, especially if the soil pH is not within the preferred range.  Foliar applications of OmniSure in winter crops are a convenient, efficient and cost-effective tool to overcome deficiencies.  OmniSure is easy to tank-mix with many chemicals which reduces application costs and enables applications in a timely manner.

Mr Thomas added, “We know growers need to make applications as efficiently as possible.  In winter the number of available spray days can be low due to weather conditions and reduced daylight hours.  By combining your OmniSure application with your cereal fungicide you are well placed to get both products on at the right time.  The unique chelation system allows much better tank-mix compatibility compared to sulphates and older chelates.”

Growers who anticipate trace element deficiencies should contact their local Elders Agronomist to establish a monitoring program and formulate a plan including the OmniSure range which covers Copper, Manganese, Zinc, Iron, Boron, Multi and Zinc/Manganese/Copper combination.

“It’s the simple and cost-effective way to make sure the money you invest in trace elements delivers the return you need through improved nutrient uptake, less passes with the sprayer, compatibility with many chemicals and more money in the bank at the end of the year.  With lower use rates than other chelated trace elements, OmniSure is cost effective and technically superior to ordinary products, a rare combination these days,” Mr Thomas concluded.
