Short summary
Fungal necromass carbon (FNC) contribution to mineral-associated organic carbon (MAOC) and particulate organic carbon (POC) was higher than bacterial necromass carbon (BNC). In 0–20 cm, FNC and BNC contributed more to MAOC, their contributions shifted toward POC in 20–100 cm. Microbial necromass carbon was affected by total nitrogen, mean annual rainfall, and electrical conductance in 0–20, while affected by available potassium, SOC, and mean annual temperature in 20–100.
