Carbon dynamics of sodic and saline soils following gypsum and organic material additions: A laboratory incubation

Wong, Vanessa; Dalal, Ram; Greene, Richard


Carbon fluxes in sodic and saline soils were investigated by measuring the soil microbial biomass (SMB) and soil respiration rates under controlled conditions over 12 weeks. Gypsum (10 t/ha) and organic material, as kangaroo grass (10 t/ha), were incorporated in an acidic and an alkaline saline-sodic soils. Cumulative soil respiration rates were lowest in the sodic and saline soils without amendment, while the highest rates were found in those soils that had organic material addition. The...[Show more]
