Carbon Sequestration in microaggregates of no-tillage soils with different clay mineralogy
MetadataShow full item record
This study compares the soil organic carbon (SOC) sequestration of three different soil types under no-tillage and conventional tillage. In all three soil types, soils under no-tillage had greater total SOC and greater C in microaggregates. More than 90% of the difference in total SOC between no-tillage and conventional tillage was attributable to the difference in microaggregate-associated C, regardless of clay mineralogy differences.
