Long-term elevated CO2 and warming enhance microbial necromass carbon accumulation in a paddy soil
Soil microbial necromass plays a critical role in soil organic C (SOC) sequestration, while the long-term response of microbial necromass to climate change remains largely unclear. Here, we used amino sugars a...
