It combines macro-, meso- and micronutrients: nitrogen, potassium, magnesium and sulphur together with boron, manganese, zinc, copper, iron, molybdenum and cobalt and a-amino acids. Manganese, zinc, copper and iron are chelated with EDTA for rapid uptake by the leaves. It corrects the boron, sulphur and manganese deficiency that causes pollen sterility and empty seeds in the heads.
