Effect of treated sewage effluents on plant cover and soil at Wadi Al Rummah, Qassim Region, Saudi Arabia

Abstract: The effect of tertiary treated sewage effluents on the plant cover and the physico-chemical properties of the surface soil (environmental characteristics) before and after the Al Rass sewage plant was investigated. The data were illustrated via TWINSPAN and canonical correspondence analysis (CCA). Five sites, 1 km apart, after the discharge point and one site (control site) before the sewage plant were examined. Eleven vegetation characteristics and ten physico-chemical properties of surface soil were studied.… Show more

“…These annual plants have high reproductive capacity phenotypic plasticity enabling them to thrive in the desert environment [41]. The preponderance of Asteraceae, Poaceae, and Brassicaceae in the present study was in harmony with other previous studies in different wadis [42][43][44][45][46][47]. Asteraceae and Poaceae families are the largest families worldwide, particularly in arid and semi-arid regions [48,49].…”

“…The plant is widely distributed in the arid areas of the desert where water is rare and high salinity is the predominant environment. Therefore, S. vermiculata is widely spread in Arabian Gulf countries and is considered to be one of the most widespread plants in central Saudi Arabia, especially the Qassim region [1]. S. vermiculata is an edible plant and Bedouins use it as an appetizer for their domestic animals, such as camels and sheep [2].…”

“…Plant growth can be affected indirectly by the quality of treated effluents. For example, the presence of high TDS in treated effluents may increase soil salinity at the disposal sites [ 47 ]. The salinity can accumulate at plant roots and cause osmotic effects, thus reducing plant nutrient uptake and consequently its growth [ 48 ].…”
