Nitrogen fixation by microbial crusts from desiccated Sahelian soils (Niger) (2001)
Malam Issa, O., Stal, Lucas J., Défarge, Christian, Trichet, Jean, Couté, A.
Cyanobacterial crusts developing on the sandy and loamy soils of fallow lands in the Sahel (Niger) were investigated for their potential to fix nitrogen. Three sites were selected in this arid...
