The purpose of this study was to investigate the effect of irrigation with sulfur water on the chemical and physical properties of soil, land cover, and adaptation of some living organisms. This study was set out to answer the following research questions: • What are the hydrological characteristics of sulfur water in Saya Spring, in Samail? • What are the chemical & physical properties of the soil over which sulfur water flows? • What is the nature of the land cover irrigated with sulfur water? • What classes of organisms have shown their adaptation to sulfur water? The research was applied to the sulfur- spring site in the town of Saiya in Samail. The water protocol was applied to sulfur water, and an analysis of minerals and materials was done on water samples. Soil protocol was also applied to samples from four sites of topsoil (5-20 cm) over which sulfur water flows. In addition, the land cover protocol was also applied to crops irrigated with sulfur water. The results of the research indicate a medium-risk salinity of sulfuric spring water. The results also show that it contains a percentage of potassium and nitrate, and this would increase soil fertility. The soil through which the sulfur spring water flows was characterized as a simple alkaline (pH = 8.3) and its easy-to-crush granular structure with clayey clay tissue, during which many roots and a high percentage of carbonate appeared indicating the effect of the use of sulfur water on chemical and physical changes in the soil. The soil fertility is indicated by a high percentage (92%) of tree density in the area. It has also noted the presence of small ponds (repelling) swimming in these water. Thus, the researchers recommend the possibility of using sulfur spring water for irrigation if its properties are studied and evaluated.
