Urea-ammonia treatment of straws in the tropics involves mixing 1.0 kg of air dry straw with 1.0 kg of a 40 g/kg urea solution and storing under plastic for at least 4 weeks (Schiere and Ibrahim, 1989). The economics of treatment is dependent on the cost of urea. Treatment cost would reduce, if on-farm-produced urine, e.g. cow urine, could be used as a source of urea. However cow urine is dilute and may contain only 10 g/kg urea or less (Owen, 1993). The present study therefore investigated varying concentrations of urea solution for treating wheat straw at a tropical temperature.
