Fluid Fertilizers - Mississippi State University
extension.msstate.eduCommon Solution Fertilizers Urea-ammonium nitrate solutions (UAN) are urea and ammonium nitrate dissolved in water. Because of the urea content, to avoid volatilization losses of nitrogen (N) to the atmosphere, you must follow the same constraints in managing UAN as you do for dry urea. Avoid surface applications in hot, dry weather.
