Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid widely used as a powerful chelating agent. It binds metal ions through multiple coordination sites, forming highly stable complexes with metals such as iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), calcium (Ca), and magnesium (Mg). Chemical Formula: C₁₀H₁₆N₂O₈ CAS No.: 60-00-4 Molecular Weight: 292.24 g/mol EDTA is typically supplied as a white crystalline solid, while its sodium salts and metal-chelat

Zinc is an essential micronutrient for plant growth and development, involved throughout the entire growth cycle and serves as a core element regulating physiological metabolism, yield formation, and stress resistance.

Chelating agents bind micronutrients (Fe, Zn, Mn, Cu, Ca, Mg, B) into stable, plant-available forms, preventing soil fixation and improving uptake.

Different fertilizers serve different purposes at different stages. Only by clarifying these relationships can fertilization become more targeted and effective in achieving stable seedlings, vigorous growth, higher yields, and improved quality.
