Web8. dec 2024 · Results showed that although buried terrace soils contained 1.7 times more unprotected SOC (i.e., coarse particulate organic carbon) than non-terraced soils at comparable soil depths, a significantly lower potential soil respiration was observed relative to a control (non-terraced) profile. Web30. mar 2012 · Soil organic carbon (SOC) is usually divided into labile C with a small size and rapid turnover and recalcitrant C with a large size but slow turnover. Generally, it is difficult to detect significant changes in soil total C and N contents because of their high background values and great heterogeneity of soils [9].
