Contrasting response of fungal versus bacterial residue accumulation within soil aggregates to long-term fertilization

open access: yesScientific Reports, 2022
Soil microorganisms are critical for soil carbon (C) cycling. They primarily regulate the turnover of the soil organic C (SOC) by adjusting their community structure, and contributing residues with a considerable amount to the resistant SOC. Nevertheless,
