EDTA chelates are stable complex compounds formed between ethylenediaminetetraacetic acid (EDTA) and metal ions. These chelates keep metal ions in soluble and bioavailable form, making them widely used in agriculture, food, pharmaceutical, and industrial applications. Chelation protects mineral ions from being prematurely broken down, making chelated minerals more stable and easily available for plant uptake.
