Descripción:	Ammonia losses by volatilization from five rates of urea or ammonium nitrate surfacce-applied coastcross pasture, grown on a dark red latosol (Hapludox) in Sao Carlos, SP, Brazil, under tropical altitude climate, werw measured. Volatilized ammonia was absorbes in traps placed on soil surface. The mean losses from urea applied after five sucessive cuttings of the grass were 15,24,34, and 40% for rates of 25, 100 and 200kg ha per cuntting respectively.
