EDTA Na2

General Information

Ethylenediaminetetraacetic acid disodium salt (EDTA Na2) is a white crystalline powder that is highly soluble in water and has excellent chelating properties.

The main use of EDTA Na2 is as a chelating agent. It can form stable complexes with metal ions, altering their properties and applications. In agriculture, EDTA Na2 is widely used in the production of agricultural chemical micronutrient fertilizers. The chelating ability allows EDTA Na2 to "wrap around" metal ions, forming soluble complexes that are bioavailable to plants. This prevents metals from precipitating or binding to soil particles. EDTA Na2 is particularly useful for supplying micronutrients like iron, zinc, manganese and copper which are essential for plant growth and development. By keeping these metals in plant-available forms, EDTA Na2 enhances fertilizer efficiency and crop yields.
