Urease Inhibitors

AgrotaiN, a urease inhibitor, was introduced into the marketplace recently. This product has been shown to be effective in reducing the potential for urea loss when either urea or UAN solutions are surface applied without incorporation. Ammonium thio-sulfate has also been proposed as a urease inhibitor. However, data collected in several states have not shown it to have either urease- or nitrification-inhibitor properties.
