Conteúdo: | Extractable soil sulfate was measured by precipitating as Ba133SO4 and counting the activity of the Ba133 ir by reducing the sulfate to H2S and measuring the methylene blue formation. Agreement between the two different methods was assumed to indicate accu- racy of analyses. Based on this assumpations, reliable measurements were possible on all subsurface soil extracts and surface soil extracts containing >2 ppm sulfate sulfur.
