Similarly, soil inorganic N contents in this study were also over two times (2.32 and 2.09 for the K. candel and B. gymnorrhiza pots, respectively) higher for the wastewater treatments than those for the controls under low salinity condition (freshwater). However, slower rates of increase resulted from the wastewater treatments under saline water condition (1.37 and 2.03 for the K. candel and B. gymnorrhiza pots, respectively).
