To evaluate the effect of different sources of sulfur and manure inoculated with Thiobacillus on sulfur and phosphorus availability in the soil and corn grown in a calcareous soil, a greenhouse experiment was conducted based on randomized complete block design with 3 replications. The treatments included S (elemental sulfur), SIB (domestic bentonite sulfur), SDB (foreign bentonite sulfur), S+M (elemental sulfur+manure) and IN (control) at 3 levels of fertilizer, i.e. S0, S1 and S2 (0, 25 and 50 mg S .kg-1 soil), respectively. After imposing the treatments, corn seeds were planted and harvested after 8 weeks. The results showed that S+M and S treatments significantly increased soil sulfate and phosphorus availability compared to the control. The main effect of all treatments increased corn plant yield and sulfur uptake as well as phosphorus, chlorophyll content, and leaf area index compared to the control. The results showed that the use of sulfur along with an organic matter source in the calcareous soil sample used in the experiment significantly (P<0.01) increased the availability of soil phosphorus and sulfur, and improved growth of corn.
