Plain Language Summary

It is now widely accepted that the majority of tropical landscapes are in transition from disturbance to recovery. Remediation efforts are occurring in Central and South America, attempting to recuperate the soils, often using indigenous nitrogen (N)-fixing tree species. Tree species-generated soil microbial heterogeneity might be important in facilitating regeneration of forest vegetation growth and, although some work has identified these efforts may enhance the soil carbon (C), there have been few studies conducted on how these trees are affecting the below-ground soil biological dynamics in these regions. Here, we explored how and to what extent individual plant effects of a native N-fixing and non-N-fixing plant has affected the below-ground soil C and N metrics and soil bacterial and fungal community composition.
