9772. Vigil, M.F. and D.E. Kissel. 1988. Evaluation of urea nitric phosphate for cool season grasses.. Kansas Fertilizer Research, p. 30-31..
Previous studies have compared urea and ammonium nitrate for forage production of cool-season grasses. Results from these studies have generally been similar, although sometimes production has been less with urea in the first year or two of the study. Lower forage production from urea treatment than from ammonium nitrate (AN) is usually attributed to ammonia loss from urea or perhaps increased immobilization of urea. The new urea-nitric phosphate (UNP) fertilizer offers the potential to reduce NH3 loss and or immobilization, therby resulting in improved forage production.
