Abstract Soil salinization adversely affects soil quality and ecosystem. Many researches have tried to ameliorate saline soils by conditioners. However, little is known about the differences in responses of bacterial communities natural artificial conditioners applied soils. Therefore, this study, effects humic acid (IK), synthetic polymer (IP), composite material (IF) (mixture IK IP (1:1)) on community structure functional genes were evaluated clarify their differences. The results showed that application three significantly reduced pH Na + content but increased alkaline phosphatase, urease, invertase catalase activities, diversity, nutrients, compared control (no conditioner). relative abundance (e.g., Subgroup_6 , RB41 MND1 KD4‐96 ) metabolic functions Two‐component system Biosynthesis amino acids) increasing nitrogen maintaining K balance. phosphatase urease activities as well Gemmatimonadaceae Quorum sensing carbon metabolism) organic carbon/nitrogen content. IF available regulated pathways ABC transporters microbial metabolism). On whole, IK, IP, could regulate function This study clarifies difference different amelioration from perspective microbiology, provides a reference for arid areas.
