Abstract: Effect of different basal dressing application methods on soil ammonia volatilization was studied by using forced draft enclosure in winter wheat fields.The results indicated that fertilizer placement considerably influenced ammonia volatilization.Surface fertilizer application favored ammonia volatilization.The daytime cumulative volatilization loss amounted to 46.08%,while fertilizer incorporation and surface fertilizer application followed by heavy irrigation both markedly reduced ammonia volatilization,the daytime cumulative loss hardly greater than 10%.The duration of ammonia volatilization with surface application lasted for twelve days,while that with the other two application methods did not exceed six days.

Key words: Ammonia volat ilizat ion, Forced-draft enclosure, Winter wheat
