Minor and trace elements are regarded as essential for plant growth, albeit required in minimal quantities. These elements are predominantly positively charged, classifying them as cations that readily adhere to clay particles, where they are susceptible to rapid oxidation. Consequently, the chelation of these elements is a critical process to enhance their availability to plants and serves as a vital measure to prevent oxidation and adhesion to clay soil particles.

Chelating agents such as EDTA, EDDHA, EDDSA, and amino acids facilitate the mobility of these essential elements within the soil solution and through plant stomata. Therefore, implementing chelation strategies is imperative to adequately supply plants with their necessary elements.
