摘要：

Total sulphur in soils was determined by ignition with a NaHCO3/Ag2O mixture, extraction with HCI and measurement of sulphur by inductively coupled plasma-atomic emission spectrometry. Significant spectral interference from other extracted elements (mainly iron and aluminium) was corrected using an off-peak background reading. Recovery of sulphur added to soil as K2SO4 was complete and barium did not interfere when added in amounts equivalent to 2000-mu-g g-1 soil. The total sulphur values for a range of New Zealand pastoral soils determined by this method were on average 104% (SEM = 1.4) of the values obtained by the NaOBr oxidation method of Tabatabai & Bremner (1). The method enables analysis of relatively large sample numbers.
