farmSPEC
farmSPEC remains in the forefront of product development in the plant nutrition and soil fertility business with its range of highly sought after coating and beneficiated raw material products. Supplying Manufactures and Blenders globally has catapulted farmSPEC as a leader in natural raw material additives and coatings capable of converting some of the large commodities such as Urea and MAP into far more efficient versions, thereby saving costs and getting far better results for its clients.
The importance of micronutrients in blended fertilizer is essential. Micronutrients used correctly can supply the plant from the germination stage right through the season up to harvesting. The crop will never experience a micronutrient deficiency at any time in its life cycle. Different locations have proved time and again that it pays to fertilize with zinc sulphate and micronutrients.
MOST IMPORTANT MICRONUTRIENTS
JUSTUS VON LIEBIG’S LAW OF THE MINIMUM
Justus Freiherr von Liebig was a German chemist who made a major contribution to agriculture in the 19the century. Von Liebig’s Law of the Minimum states that yield is proportional to the amount of the most limiting nutrient. Therefore, if the deficient nutrient is applied, yields may be improved to the point that some other nutrient is needed in greater quantity than the soil can provide, and the Law of the Minimum would apply in turn to that nutrient.
Due to the centuries-long use of animal dung for fertilisation, many early scientists believed that the nutrients needed by plants were organic rather than mineral. Liebig proved this theory wrong in research that showed that plants need mineral elements from the soil, carbon from carbon dioxide in the air and hydrogen and oxygen from water. Research made it clear that Liebig’s Law of the Minimum also applied to micronutrients. Thus, if there is a shortage of any of the micronutrients, the farmer cannot achieve optimal production.
