Soil CO2 efflux is a pivotal component of agro-ecosystem C budgets. It considered proxy indicator biological activity and descriptor soil quality that strongly linked to agricultural management. We investigated the effects fertilization practices (organo-mineral (OMN) versus chemical (C)) on under-vine (TSR) in an Italian rainfed vineyard (cv Chardonnay). The TSR was measured using chamber technique as follows: close multi-chamber system (prototype) placed under vine. Data (CO2, temperature, moisture) were acquired hourly during two consecutive years (2021 2022) from flowering berry ripening. Physical–hydrological parameters determined, seasonal trends TSR, moisture assessed. measurements fluctuated for 2021 season, ranging 1.03 1.97 µmol CO2∙m−2∙s−1 treatment, while OMN ranged 1.24 1.71 CO2∙m−2∙s−1. Extreme weather conditions (2022) highlighted differences between agronomical practices, decoupling found water content, with being controlled primarily by temperature. At daily scale, findings showed reached its minimum early morning hours (5:00–8:00). results promote organic–mineral nutrition improved practice carbon storage (restoration organic fraction) reducing permitting preservation stabilizing hydrological traits preserving biotic activities.
