Abstract

Background and ObjECtives: In calcareous soils of Iran, due to high pH, nutrients are slightly soluble and their absorption by plants is difficult. In order to solve these problems and to achieve optimal yield in such soils, the use of sulfur as a corrECtion agent is nECessary to reduce the local pH of the soil and increase the solubility of nutrients. The aim of this study was to evaluate the sulfur effECt inoculated with Thiobacillus bacteria on some chemical properties of soil (pH, elECtrical conductivity, pHospHorous, sulfate iron and available zinc) and nutrients concentration in wheat grain in four areas of Kermanshah province with different available sulfur. Materials and Methods: An experiment was carried out in four sites (Chogha Narges, Mahidasht, Najaf Abad and Ghomsheh) with different levels of available sulfur (7, 13, 18, 27 mg kg-1soil) in Kermanshah Province. Sulfur was applied at 0, 250, 500 and 1000 kg ha-1 as Pastille Sulfur (PS), using complete randomized blocks design with three replications in a during cropping season 2015-2016. Seeds of wheat were planted in plots. Before cultivation, the pHytochemical properties of soils were analyzed using standard laboratory methods. Soil samples at tillering, stem elongation and post harvesting stage was collECted for determination of pH, elECtrical conductivity (EC), pHospHorous (P), sulfate (S-SO4), iron (Fe) and available zinc (Zn). Finally, grain yield and concentration of nutrients were determined using routine methods. Results: The result showed that PS significantly dECreased the soil pH and adversely, increased EC, P, S-SO4, soil DTPA-extractable Fe and Zn in the Chogha Narges, Mahidasht (P<0. 01) and in Najaf Abad and Ghomsheh (P<0. 05) at tillering, stem elongation and post harvesting stage compared with the control. The lowest pH and highest EC, P, S-SO4, Fe and Zn value were observed with 1000 kg ha-1 So at stem elongation. After harvesting due to the reduction of sulfur oxidation and buffering capacity of soils, pH and nutrients gradually reduced in comparison to the stem elongation stage. Also, nutrients concentration (P, S, Fe and Zn) in wheat grain was significantly increased by the application of PS compared to control. The highest nutrients concentration was observed with application of 1000 kg So ha-1. Conclusion: The effECt of simultaneous application of sulfur and Thiobacillus bacteria on the chemical properties of the soil and nutrients concentration in wheat grain was promising, which indicates its good potential for use in agriculture. Each calcareous soil, has a spECific potential for sulfur oxidation which depends on its characteristics and the only amount of calcium carbonate is not a suitable measure for the application of sulfur to increase the solubility of nutrients.
