Evaluating soil carbon stability by combining δ13C and soil aggregates after afforestation on agricultural land and thinning management

Background and aims Afforestation and thinning management are effective ways to mitigate global warming. Soil carbon reconstruction mechanisms can be effectively explored by linking soil aggregates and isotopic 13 C. Methods Soil samples were collected from agricultural land (AL) and larch plantatio...

Description
Summary:Background and aims Afforestation and thinning management are effective ways to mitigate global warming. Soil carbon reconstruction mechanisms can be effectively explored by linking soil aggregates and isotopic 13 C. Methods Soil samples were collected from agricultural land (AL) and larch plantations (established in 1965 and thinned in1995, UT: 2500 tree‧ha −1 , MT: 1867 tree‧ha −1 , and ST: 1283 tree‧ha −1 ). The soil was separated into three aggregate sizes (LMAC: > 2 mm, SMAC: 2–0.25 mm, MIC: 0.25–0.053), minerals associated with organic matter (MAOM:
