Biochar is a promising carbon sequestration strategy, however, the mechanisms underlying regulation of microbial-derived (M-C) and plant-derived (P-C) in soil organic (SOC) formation stabilisation remain elusive, constraining accurate predictions pool. This study examined biotic abiotic factors that influence plant microbial biomarkers SOC accumulation. A 5-year field experiment was conducted temperate wheat-maize agroecosystem north-western China, with three treatments: (i) no straw incorporation (C), (ii) (S), (iii) + biochar (SB). The results showed M-C reached carrying capacity gradually, whereas P-C selectively continuously accumulated, displaying complementary S-curve pattern. Straw increased SOC, biomass (MBC), dissolved (DOC) contents, which stimulated richness enzyme activities, resulting 29.1 % 25.5 increase respectively. mineralisation (26.2 %) led to significantly lower content S compared SB practice. combined decreased DOC (18.5 comparison incorporation, suppressed particularly Actinobacteriota (12.3 β-N-acetyl-glucosaminidase (24.2 %). It resulted 10.9 14.3 fungal-to-bacterial necromass ratio (F/B), respectively, while decreasing by 9.6 over 5 years. Overall, effectively enhanced reduced mineralisation, suggesting its potential augment quantity stability pools mitigate global climate change.

Abstract Microbial necromass is a crucial contributor to the formation of soil aggregates and serves as key source stable organic carbon (SOC). However, how tillage practices regulate microbial accumulation within aggregate fractions at different depths remains unclear. Thus, 20‐year field experiment was carried out identify (MC) distributed in its contribution SOC under no‐till (NT) plow (PT) rice‐wheat rotation system. The results showed that NT significantly increased bacterial fungal (C) concentrations both macro‐ micro‐aggregates (>0.25 <0.25 mm), enhanced MC compared with PT 0–5 cm topsoil depth. decreased concentration by 12.4% mainly attributed lower C 21.6% 27.6% 5–15 subsoil There no significant difference for mineralization per unit between PT, which can be equilibrium labile (e.g., dissolved C). Random forest partial least squares path model demonstrated total nitrogen, available NH 4 + , NO 3 − positively regulated β‐glucosidase activity, thus affected concentration. nitrogen activity micro‐aggregates, lowered Our findings highlights reduced due micro‐aggregates.
