Precipitation leaches soil organic matter (SOM), transporting it downward where it accumulates at the soil–bedrock interface. Intensive agriculture, particularly tillage, accelerates this process. Microbial decomposition of SOM generates CO2, forming a gas-rich soil layer (GRSL)—a phenomenon long hypothesized but never directly confirmed until now. Drilling on the Harbechy Plateau (Moravian Karst) revealed a GRSL with a thickness of ~0.8 m, CO2 concentrations averaging 1.5–3 vol. % (peaks of 4–6 vol. %), and isotopic signatures (δ13C) indicating a mix of biogenic (−25‰) and atmospheric (−8‰) CO2. These findings necessitate re-evaluation of carbon cycling models in karst agroecosystems.
