This study investigated the impact of various tillage modes on soil carbon (C) components, crop yield, enzyme activity, and ecosystem multifunctionality (EMF) in North China Plain (NCP), aiming to determine most effective practice for C sequestration region. Field experiments were conducted from 2016 using a split-plot design that included rotary (RT) deep (DT) during wheat season no-tillage (NT), subsoiling in-row (SIR), inter-row (SBR) maize season. Related based total amount straw returned. Soil bulk density (BD), organic (SOC) storage, activities, quality index (SQI), EMF, yield measured analyzed. Compared tillage-no-tillage (RT-NT), BD 0-40 cm layer decreased under other treatments 2018-2019. The component content with depth across all treatments. Treatments incorporating led higher SOC, labile (LOC), non-LOC, microbial biomass (MBC) 20-40 layer. DT-SBR DT-SIR increased SOC storage. Enzyme activities highest 0-20 RT-SBR RT-SIR, while layer, activity peaked DT-SIR. SQI value was observed RT-SIR both years. Meanwhile, EMF values 30-40 2018, ranged -0.79 -0.08. Key factors influencing MBC, LOC, dissolved (DOC), showing strong positive correlation SQI. Subsoiling enhanced RT DT being 6697 6587 kg ha-1, respectively. In conclusion, promoted transformation SQI, EMF. These benefits contributed greater deeper layers, offering sustainable approach management fluvo-aquic soils NPC.
