The implication of Omnia’s science-based business philosophy is that an immense amount of research is conducted, both on the farm and behind the scenes, with continuous product and service refinement and development being the primary goal.

Omnia Nutriology® has a dedicated team of agronomists that work directly with farmers and agents across the country to ensure that our farmers get the best products and soil health solutions for their farms.

Maize is the most important grain crop in Southern Africa and prices are dramatically influenced by any indication of under or over production.

The facts and equations remain; by 2050 the world will need to produce 70% more food to feed 9 billion people. In developing countries like Africa, food production will need to double.

The recent droughts and increasing input costs have forced the modern grain farmer to work more efficiently. Fertilizer is one of the greatest expenses and its application in terms of placement should therefore be done as effectively as possible.

The profitability of maize production in the semi-arid regions of South Africa depends on the efficient use of limited rainfall. Maize profitability can vary widely due to the highly variable nature of rainfall, both in timing and quantity.

The term nitrogen use efficiency or NUE has been used for some time. Since its origin in the early 80s, a wealth of ratios were applied to calculate NUE (Moll, Kamprath and Jackson, 1982).

Fertigation is often referred to as the practice of applying fertilizer in a liquid or water soluble form to a crop through the irrigation system.

According to criteria recommended by Arnon and Stout in 1939, there are 18 nutritional elements needed by plants for growth. However, these elements need to be available in the soil for the plant to take up.

World sugar production has grown from around 50 million tonnes in 1965 to roughly 175 million tonnes today.
