Microbiotic soil crusts in the Sahel of Western Niger and their influence on Soil POROSITY and water dynamics (2009)

Malam Issa, Oumarou, Défarge, Christian, Trichet, Jean, Valentin, C., Rajot, J.L.

Microbiotic soil crusts are common features of the surface of fallow land in Western Niger. We investigated the interaction between these microbial covers and the porosity and water dynamics of soils...

Effects of the inoculation of cyanobacteria on the microstructure and the structural stability of a tropical soil. (2007)

Malam Issa, Oumarou, Défarge, Christian, Le Bissonais, Yves, Marin, Béatrice, Duval, Odile, Bruand, Ary, ...

Cyanobacteria are widespread photosynthetic microorganisms among which some are able to fix atmospheric nitrogen. We investigated the impact of indigenous cyanobacteria strains (Nostoc) inoculation...

Nitrogen fixation by microbial crusts from desiccated Sahelian soils (Niger) (2001)

Malam Issa, Oumarou, 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...

Role of a cyanobacterial cover on structural stability of sandy soils in the Sahelian part of western Niger (2001)

Malam Issa, Oumarou, Le Bissonais, Yves, Défarge, Christian, Trichet, Jean

Microbiotic soil crusts, mostly formed by cyanobacteria, are widespread on the surface of fallow land in western Niger. They lie adjacent to completely bare soils. We have investigated the structural...

Morphology and microstructure of microbiotic soil crusts on a tiger bush sequence (Niger, Sahel) (1999)

Malam Issa, Oumarou, Trichet, Jean, Défarge, Christian, Couté, A., Valentin, C.

Microbiotic crusts resulting from the colonization of soil surfaces by communities of micro-organisms dominated by cyanobacteria, eucaryotic algae or lichens are widespread in arid and semi-arid...
