In the agricultural field it is often necessary to dose with traces of heavy metals e.g. Fe – Mn – Zn used as micro-nutrients. The complexing metal properties of StarLig products with high solubility and low cost, create an ideal carrier for this purpose. Depending on the process requirements, LignoStar can provide several different lignosulfonate solutions for this application. Our technical staff is available to provide assistance for sampling, laboratory or industrial testing and to determine the best conditions for StarLig applications.
