Abstract To study the effect of veterinary antibiotics sulfamethazine (SMZ) in low, medium and high concentrations and their interactions with different N fertilizers on NH₃ volatilization from cropland, an in-situ observation experiment was conducted during the 2016~17 winter-wheat season. The treatments included no fertilizer and no antibiotics applied (CK), compound fertilizer used as basal fertilizer, with the addition of 0, 5, 15, 30mg/kg SMZ respectively (CF, CF+SMZ5, CF+SMZ15, CF+SMZ30), pig manure used as basal fertilizer, with the addition of 0, 5, 15, 30mg/kg SMZ respectively (CM, CM+SMZ5, CM+SMZ15, CM+SMZ30). Urea was applied as topdressing in all fertilizing treatments. The results showed that the NH₃ volatilization rate had no significant difference among all treatments during the basal fertilizing period (P > 0.05), while it had an extremely significant difference among all treatments during the topdressing period (P<0.01). SMZ in medium and high concentrations obviously increased the NH₃volatilization rate. During the entire sampling period, the percentage of applied N lost as NH₃-N for CF+SMZ5, CF+SMZ15, CF+SMZ30, CM+SMZ5, CM+SMZ15 and CM+SMZ30 treatments was 5.5%, 6.6%, 13.9%, 10.7%, 11.0%, 12.4%, 11.9% and 16.9%, respectively. In comparison with the same basal fertilizer and no SMZ use treatment, CF+SMZ15, CF+SMZ30 and CM+SMZ30 treatments significantly increased cumulative NH₃ volatilization (P<0.05) and they had 2.5, 2.0 and 1.5times as many percentages of NH₃ volatilization as CF or CM treatment, respectively. This indicated that the promoting effect of NH₃volatilization caused by SMZ mixed with compound fertilizer was much greater than that together with pig manure. Therefore, the effect of veterinary antibiotic on NH₃ volatilization in soils cannot be ignored. In order to reduce the environmental pollution of veterinary antibiotics, we should strengthen the management of veterinary antibiotics and need to further explore the mechanism of different veterinary antibiotics affecting soil NH₃volatilization in the future.
