Impacts of soil-soluble anions on wild and cultivated herbaceous species: implications for soil phytoremediation

This study addresses the growing problem of soil salinity. In Mediterranean regions, disused solid waste landfills have given rise to disturbed ecosystems. At such sites, both mobile soil anions and cations have toxic effects on plants. Thus, detailed knowledge of these effects is needed for the phy...
