Abstract
Improved urease inhibitors comprise one or more polymers containing alkenylphenyl sulfonate repeat units, which may be applied to or mixed with a variety of urea-containing fertilizers in order to substantially prevent urea decomposition when applied to soil. The inhibitors may be in the form of homopolymers such as polystyrene sulfonate, or as copolymers containing alkenylphenyl sulfonate and other, different repeat units. The inhibitor polymers may be in free acid, partial salt, or complete salt forms, and are water soluble.
