With the high cost of nitrogen fertilizer, farmers need to get optimum use of the product. Reviewing their management plan and making needed changes can potentially save money without compromising yield. Most recent research shows it takes about three quarters of a pound of nitrogen per bushel to reach corn’s maximum yield potential, but some producers use much higher rates, said John Grove, University...

Agrotain is a liquid urease inhibitor that can be impregnated onto dry urea or tank mixed with liquid fertilizer that contains urea such as urea-ammonium nitrate (UAN).

Today’s cattle producers are facing record-high fertilizer prices. Adding insult to injury, this is on top of two years of record-drought causing poor growth of pastures and hayfields. Because of this, farmers are shopping around for any cheap source of nitrogen (N) and praying for rain to bring their forages back to life. Producers should know that not all sources of N are equal and cheap sources could end...

Research is proving what rice growers have suspected for years — that a low rate of nitrogen applied to rice in the one- to three-leaf growth stage has a positive effect on production. “Collaborative research in 2005 and 2006 with the University of Arkansas, Mississippi State University and the University of Missouri showed that rice plant height was increased by about 2 inches when 20 pounds of nitrogen...
