Abstract
An aqueous urease inhibitor and/or nitrification inhibitor formulation includes an aqueous wax dispersion, which includes about 10-50% by weight high melting point emulsifying wax, water to make up to 100%, at least one inhibitor active in an amount of 1 wt %-30 wt % of the aqueous wax dispersion, and a dispersing clay in an amount of 5 wt %-50 wt % of the aqueous wax dispersion.
