Trace Elements

Minor and trace elements are recognized as essential for plant growth, albeit present in minimal quantities. These elements predominantly exhibit positive charges, which categorize them as cations that adhere to clay particles and are prone to rapid oxidation. Consequently, the chelation of these elements is a critical step to enhance their availability to plants and serve as a vital measure to mitigate oxidation and adhesion to clay particles.

The chelating agents, such as EDTA, EDDHA, EDDSA, and amino acids, facilitate the mobility of these elements within the soil solution or via the stomata. Thus, the process of chelation is imperative to adequately meet the nutritional requirements of plants regarding these essential elements.
