Tillage systems can changes in soil organic carbon dynamics and soil microbial biomass by changing aggregate formation and C distribution within the aggregate. However, the effects of tillage method or straw return on soil organic C (SOC) have showed inconsistent results in different soil/climate/ cropping systems. Soil TOC and labile organic C fractions contents were significantly affected by straw returns, and were higher under straw return treatments than non-straw return at three depths. | Soil aggregation and organic carbon fractions and indices in conventional and conservation agriculture under vertisol soils of sub-tropical ecosystems: A review
