The positive effects of sulfur on reducing the reaction of calcareous soils, increasing the solubility of micronutrients, as well as high consumption of phosphorus, and its role in the modification of saline and sodium soils and the inorganic properties of water are proven. Sulfur is added to soil in appropriate conditions in terms of moisture, heat, organic matter and active sulfur-oxidizing microorganisms, which are predominantly thiobacillus bacteria, eventually converting the soil to sulfuric acid and reducing soil pH. As a result, the solubility of many elements and their uptake by the plant are increased. Sulfuric acid is produced by the oxidation of sulfur with lime (calcium carbonate) present in the composition soil and dissolved calcium. By replacing calcium with exchangeable sodium and then leaching it, the physical and chemical conditions of the soil improve. Sulfuric acid is one of the sulfur derivatives that can be used to modify sodium soils containing lime and other calcium sources. Research has shown that with the consumption of 500 to 1000 kg of milled sulfur, alfalfa yield increased by about one ton per hectare. The results of a comparison of the three sulfuric acid modifiers showed that sulfuric acid in general had an effect on sulfuric acid yield. Alfalfa was higher than the other two materials Kolbasi et al. (1988) examined the effect of sulfur on iron, zinc and manganese uptake, which significantly reduced soil pH compared to control and reduced the amount of iron, zinc and manganese available. Increases plant uptake It has been reported that the consumption of sulfur simultaneously with its oxidizing bacteria was able to An equivalent effect of phosphorus fertilizers on soil uptake The results of the research by Ghorbani et al. (2003) showed that bentonite sulfur supplementation with animal manure increased sugar beet yield compared to control. It was reported that consumption of 4.2 tonnes elemental sulfur With 20 tonnes of animal manure in a sodium saline soil,
