Understanding the process of soil organic carbon (SOC) sequestration and mineralization in aggregates is pertinent to mitigate climate change and minimize risks of soil degradation. The NT system increased the proportion of >2 mm aggregate fraction and reduced the proportion of 0.25 mm macro-aggregate fraction also significantly increased in the 0.00-0.5 m layer in NT system. However, those within the 2.00-0.25 mm aggregate fraction were significantly reduced in the 0.05-0.200 m layer under NT system. Straw incorporation increased not only the SOC stock in bulk soil, but also the proportion of macro-aggregate, aggregate associated with SOC and humic and fulvic acids concentration within the aggregate. | Conservation tillage and fertilization impact on carbon sequestration and mineralization in soil aggregates in the north west IGP under an irrigated rice-wheat rotation: A review
