Denitrification potential and its correlation to physico-chemical and biological characteristics of saline wetland soils in semi-arid regions

► Four different halophyte soils in saline wetlands of China were investigated. ► Analyze potential denitrification rate (PDR) and kinetics among the saline wetland soil. ► Characterize the correlation of PDR with its factors. ► Identify significant factors to denitrification potential using PCA.
