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...

The size of aggregates stable to water increased with time for both treatments. EPS produced the highest increase in aggregates >2 000 μM (11.21 fold) at day 180 and aggregates between 500 and 1 000 μm (14.22 fold) at day 360. With sheaths, the highest increase was for aggregates between 1 000 and 2 000 μm (18.57 fold) at day 180 and >2 000 μm (18.08 fold) at day 360. Sheaths produced higher increases that EPS in the largest aggregtes in part as a consequence of a higher increase of microbial activity.
