Chelated trace elements

Chelates are stable compounds comprising a metal cation and a large organic molecule called a chelating agent or ligand. This ligand forms a protective ring structure around the cation, shielding it from external influences.

In agriculture and horticulture, chelates are used primarily on micronutrients like iron, zinc, manganese and copper. These microelements, without the complexation to a chelating agent, can precipitate caused by pH fluctuations or phosphate salts, rendering them insoluble and inaccessible for plant uptake. Chelates ensure that the microelements remain soluble and available to plants, maximizing nutrient uptake efficiency.
