Abstract

Emission rates of carbonyl sulfide (COS), carbon disulfide (CS2) and dimethyl sulfide (DMS) to the atmosphere from wheat fields treated with different fertilizers were measured by using the closed chamber method. The results showed that the emission rate of COS, CS2 and DMS was affected by wheat growth and COS was absorbed by the plants. DMS and CS2 were the predominant sulfur gases emitted from these fields. The diurnal variations of emission rates of COS and CS2 were obvious. The sulfur flux in the plot treated with organic fertilizer was higher than that in the other plots. The sulfur fluxes from different plots were in the range of -1.40 to 0.79 mg.m-2.
