Additional datasets for the effects of straw mulching on soil organic carbon content and stability in a subtropical plantation

Through a three-year field experiment in subtropical bamboo forests, we explored the response of soil organic carbon components, soil physicochemical and microbial characteristics to straw mulching, as well as their interactions, and how biochar regulates straw mulching in SOC POC、MAOC、TN、TP、AN、AP、MBC、MBN、DOC、C/N、 Above ground biomass, underground biomass, fungal residue carbon, bacterial residue carbon, free Fe Al oxide, amorphous Fe Al oxide, composite Fe Al oxide, β - D-glucosidase, N-acetyl - β - D-glucosidase, acid phosphatase, fungal gene copy number, bacterial gene copy number.
