SUPERU® Fertilizer & AGROTAIN® Nitrogen Stabilizer vs ContaiN™

SUPERU is a urea-based granular fertilizer containing active ingredients to protect against all three forms of nitrogen loss – volatilization, denitrification and leaching. 
 

SUPERU fertilizer out performs ContaiN

 

In the 2017 study conducted by the University of Missouri, eight inches of rain fell within two months after fertilizer application, creating conditions where protection against denitrification was needed. In 2018, conditions were more favorable for losses due to volatilization. With proven active ingredients for both below- and above-ground protection, SUPERU outperformed ContaiN by an average of 13 bu/acre. 

SUPERU and AGROTAIN both outperform ContaiN in NUE

Over the two-year study, SUPER fertilizer increased nitrogen-use-efficiency (NUE) by an average of 17 percent. AGROTAIN, the original, most-research proven urease inhibitor, protecting against losses due to ammonia volatilization, increased NUE by 10 percent over the two-year study compared to urea treated with ContaiN.
