Abstract:
Soil organic matter and soil aggregate stability are good indicators of soil quality and both can be positively affected by reduced tillage and residue management practices. A field study was conducted to find the impacts of tillage and residue management practices on soil carbon stock and distribution of SOC within different soil physical fractions. The study site was a 30-year experiment divided to six treatment classes, conventional tillage (CT) and reduced tillage (RT) with straw incorporated (S), straw removed (SR) and straw burned (SB). The soil was segregated into four different classes: large and small macroaggregates, microaggregates and silt and clay which were analyzed for total carbon. Reduced tillage or residue incorporation did not result in higher C sequestration but there were more water stable aggregates in the reduced tillage treatment.
