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...
