The sulphur sting

Sulphur plays a major and essential role as plant nutrient and is often called the fourth macro-element after nitrogen, phosphorus and potassium, due to its utter importance in plant physiology and metabolism. In fact, in the maize and soybean producing areas of the USA, sulphur is regarded as the third limiting major plant nutritional element after nitrogen and phosphorus.

For this reason, Omnia Nutriology® embarked on a campaign in order to inform our clients of the importance of sulphur in balanced plant nutrition. The campaign consisted of farmers’ days with Dr. Elke Bloem from the Julius-Kühn Institute for Crop and Soil Science in Germany as the keynote speaker, as well as various published articles, pamphlets and booklets.
