Few studies examine the ability of leguminous tree species to nodulate and fix atmospheric N, especially symbiotically with rhizobia; this study seeks to fill that research gap. The occurrence of nodulation was determined in 156 mature leguminous species growing in 6 natural forest areas in south-eastern Guinea and an in situ experiment of rhizobia inoculation was performed on 8 selected tree species.

This study evaluates recent reforestation programs in Afghanistan in anticipation of larger scale programs needed to address watershed-scale degradation.
