N2 - The omni-presence of Zygophyllum fabago L. (Syrian bean-caper) natural colonies in post mining areas prompted us to investigate its contributions to reclamation of mine wastes deposits′ in southeast Spain. Select plant-related (edaphic) characteristics and bio- and water soluble-Cd, Cu, Pb and Zn in rhizosphere of Z. fabagowere compared to deposits one year since application of pig slurry and marble waste. Total N in rhizosphere increased up to a factor of 20X (339 vs 17 mg N kg-1) in El Gorguel and 27X (85 vs 3.1 mg N kg-1) in El Lirio sites. Organic matter accumulation in rhizosphere from litter and roots of Z. fabagoincreased organic C from 6.6 to 19.5 g kg-1in El Gorguel and from 2.1 to 5.7 g kg-1 in El Lirio in one year. Dissolution of inorganic C takes place due to organic acids from root exudates of Z. fabago. Reduction in bio-available Cd, Cu, Pb, and Zn in rhizosphere of Z. fabagoat El Lirio is attributed to increase in pH from 5.3 to 7.7 through marble waste addition, although increased cation exchange capacity may also have played a role. Addition of marble waste to encourage colonization by Z. fabagoin acidic mine wastes deposits was recommended.
