Abstract

Sulfur oxidation in soil, reduces soil PH, increase nutrients solubility and provide sulfate for plant growth. Among sulfur oxidizing microorganisms Thiobacillus spp and heterotrophs could have the potential to sulfur oxidizing in arable soils (four groups acidophilic and neutrophilic heterotrophic and acidophilic and neutrophilic autotrophic).Two soil samples containing all four groups of sulfur oxidizing microorganisms were selected. The factorial experiment in complete randomize design established with four factors, which consisted of sulfur rates (2 levels), time (5 stages), soils (2 samples) and ORGANIC MATTER (2 levels), which have been done in three replications.At 5 time stages population of four groups sulfur oxidizing microorganisms, PH and value of sulfate productions were measured. Results indicated that after application of 0.2% sulfur, population of all four groups of sulfur oxidizing microorganisms was significant (p<0.01) increased, Also after application of 1.5% ORGANIC MATTER population of heterotrophs sulfur oxidizing microorganisms was increased and population of autotrophs sulfur oxidizing microorganisms was decreased.Results showed that after 20 and 80 days population of total heterotrophs and total autotrophs reached to maximum level. Study of microorganisms change trend and sulfate production trend in soil showed that efficiency of autotrophs microorganisms to sulfur oxidation and produce of sulfate is higher than the heterotrophs, also significant correlation (p<0.01) between soil sulfate concentration and population of autotrophic microorganisms specially neutrophilic autotrophs was observed.
