ABSTRACT The single‐tier mono‐cropping systems in the rain‐fed ecosystems are vulnerable to global climate change and leading unsustainability of production deterioration soil health. present investigation evaluated dynamics organic carbon (SOC) stock quality index different multitier agricultural ecosystems. comprise (1) fallow land (FL‐control), (2) perennial napier fodder grass (Napier), (3) sole rice crop rainy season (Rice), (4) cropping system mango + mahogany (MMR), (5) plum orchard, (6) aonla (MMAR), (7) peach (MMPR). After 7 years establishment, highest total SOC (TSOC) was 62.8 Mg ha −1 MMAR system, which sequestered 2.71 C year . Compared control, stabilized 1.28, 1.57, 1.5, 1.48 times more TSOC at 0.0–0.15, 0.15–0.30, 0.30–0.45, 0.45–0.60 m depths, respectively. enhanced non‐labile recalcitrant fraction by 21.1% over control. dehydrogenase, fluorescein diacetate, β‐glucosidase, acid phosphatase activities were 1.48, 1.84, 1.59, 1.9 than respectively, 0–0.60 depth. best indicators identified for microbial biomass carbon, EC, pH, bulk density. adoption agroecosystems builds‐up a considerable amount maintains better comparison mono‐cropping.
