Why Chelates
The function of chelate (organic complex) is to chemically combine to positively charged micronutrient ion (cation) such as Copper, Zinc, Iron, Manganese, Magnesium and Calcium with an organic molecule (negatively charged chelating agent). By binding the micronutrient ion in a protective grip, it protects the micronutrient ion from being tied up by negatively charged soil particles until it reaches the plant.
