Secondary elements

The effective use of secondary elements and micronutrients

By Dr. Koos Bornman (General Manager: Strategic Agricultural Services)

To support the yields achieved in recent times and still ensure quality produce, one cannot afford to neglect having an utterly complete and effective nutitional programme. Secondary and micronutrients form an important and often critical part of such a programme. Omnia specialises in and is well positioned to offer a complete secondary and micronutrient package in different forms - from single products to blends, in solid or liquid form.

During the last few years Omnia has also stepped into the exciting field where plant nutrition is combined with biostimulants and elicitors. This consequently promotes the uptake of nutrients, stimulates plant growth and increases the plant's disease resistance. A new micronutrient-containing foliar product which will soon be launched and which has been evaluated in the marketplace, for instance caused a statistically significant, phenomenal 6 tonne yield increase on tomatoes against a standard programme and also brought about a 17% additional suppression of fungal infection.

Profitability of the use of Omnia's Plus Products in grain production
Crop Area Number of facilities Year Statistical probability of yield increase (%) Average return on investment (%)
Wheat Western Cape 8 2008 96 600
Wheat Western Cape 7 2009 99 300
Wheat Central 4 2010 99 900
Maize Central 6 2009/10 96 400
Summary   25 in total 3 years Minimum 96% 300 - 900%

Omnia developed a Plus Product range about four years ago. These chemically granulated products are rich in secondary nutrients and are also covered by an organic layer enriched by the total micronutrient range, which includes chelated micro-cations. These micronutrients are applied in a unique ratio and concentration according to crop and area requirements. Table above shows the research results achieved using Plus Products. There is a predominant chance of more than 300% and even up to 900% of getting a return on investment with the use of these products. The photo above clearly shows the difference a Plus Product has on a wheat field.
