What is Agrotain?• Urease inhibitor – fertilizer additive• N-(n-butyl)thio phosphoric triamide• Controls ammonia volatilization• Improves nitrogen efficiency• For Urea and UAN solution fertilizers• Has 21 patents in 70 counties• Recognized as one of the 100 mosttechnologically significant new productsby “R & D Magazine”

Two Study Conclusions2007 Cotton Beltwide• Agrotain stabilized urea improved cotton Nuse efficiency comparable to ammoniumnitrate• Agrotain stabilized UAN dribbled was aseffective as injected
