Studies carried out in soils of the Brazilian semiarid regionreported that sulfur inoculated with Acidithiobacillus can be apromising means for the reclamation of saline sodic soils because,in general, it reduced soil pH (Stamford et al., 2004). Indeed,Stamford et al. (2007) used a mixture of sulfur inoculated with Acidithiobacillus and gypsum in equal proportions and observedexcellent results in the attributes of the amended soil; however,the effects on plant growth were not evaluated in that study.Sulfur-oxidizing bacteria have a significant ecological impact innature due to their role in promoting the availability of elemen-tal sulfur that is oxidized to sulfate and also in contributing to therelease of nutrients contained in the soil, especially phosphorus(El-Tarabily et al., 2006). Sulfur-oxidizing bacteria occur naturallyin soils, but these species are relatively less abundant in agriculturalsoils. Therefore, to obtain a satisfactory effect on saline soil recla-mation the sulfur-oxidizing bacteria should be introduced into thesoil
