Saline sodic soil changes by inoculation of Tolypothrix tenuis (cyanobacteria) sheaths or exopolysaccharide

Exopolysaccharide (EPS) and sheaths isolated from a Tolypotrix tenuis were inoculated in a saline soil, in a greenhouse experiment. EPS increased soluble C by 64%, 125% and 104% and microbial activity by 273%, 81% and 49%, at at 40, 180 and 360 days after soil inoculation, respectively. Sheath addit...

Sheaths produced higher increases that EPS in the largest aggregtes in part as a consequence of a higher increase of microbial activity. 2001 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00195022_v71_n4_p282_DeCano http://hdl.handle.net/20.500.12110/paper_00195022_v71_n4_p282_DeCano
