Application of derivative synchronous fluorescence spectroscopy (DSFS) to indicate salinisation processes of saline soils in semi-arid region

▸ Four different halophyte soils in semi-arid region were investigated. ▸ Structure and composition of FA from saline soils were analysed by DSFS. ▸ Humification indices were deduced from DSFS to indicate humification degree. ▸ Halophytes communities and soil salinisation processes were indicated by HIXs.
