Potentialities of ecological engineering strategy based on native arbuscular mycorrhizal community for improving afforestation programs with carob trees in degraded environments

•Rhizophagus is the main mycorrhizal fungi associated to carob trees.•Carob inoculation with a native AM community has a sustainable plant promoting effect in natural degraded soils.•AM inoculation has a strong positive impact on soil microbial functioning.•Ecological engineering strategy based on n...
