Conteúdo: 	Ammonium thriosulface (NH4)2S203, ATS, 12-0-0-26 S) has been reported to inhibit both nitrification of NH4 and hydrolysis of CO(NH2)2 in soil. A field test on maize was carried out adding ATS to UAN (10% by volume). Addition of ATS to UAN tended to increase grain yield and ear-leaf N concentration at silking in all tretaments, although the differences were not statistically significant at p = 0.05. The response to the addition of ATS appers to be related no N nutrition and not to S nutrition as ear-leaf S concentration always ranged over the adequate level. Due to the dry weather during the growing season, nitrate leaching was negligible; therefore it is assumed that results obtained were related with lower NH3 volatilization losses.
