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.


Sodium (Na) is one of the sixteen elements determined in a routine sap analysis in Omnia Fertilizer’s OmniSap® laboratory.


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


Often in crop production, fertilizer practices are aimed at achieving maximum yields, with little consideration given to the effect of nutrition (positive or negative) on crop quality.


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


The availability of soil moisture and nutrient uptake go hand in hand in crop production. Nutritional imbalance under drought conditions depress plant growth and productivity by affecting nutrient uptake, transport, and distribution.


It is of the utmost importance for Omnia Fertilizer to ensure that the correct scientific norms are used to interpret soil, sap and leaf analyses. The importance thereof cannot be over-emphasised, as correct soil, sap and leaf analyses and the interpretation thereof ensure economic prosperity on the farm. 


The ever increasing cost of agricultural land in South Africa makes the purchasing of land for expansion an expensive option for livestock farmers who have already reached their capacity with the natural pasture at their disposal.


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.


Understanding the underlying mechanisms involved during drought stress, gives insight into possible strategies to alleviate drought stress and to improve plant water use efficiency (WUE), nutrient use efficiency (NUE) and optimal plant productivity.
