CO2 Emissions in Layered Cranberry Soils under Simulated Warming

Sanding to bury the overgrowth of uprights and promote new growth results in alternate sand organic sublayers 0–30 cm layer cranberry soils contributing global carbon storage. The aim this study was measure CO2 emission rates soil under simulated warming. Soil samples (0–10, 10–20 20–30 cm) were incubated jars for up 105 days at 10, 20 30 °C. rate measured biweekly by gas chromatography. increased with temperature decreased deeper sublayers. Linear regression relating efflux sublayer returned R2 = 0.87. Sensitivity matter decomposition estimated as activation energy Q10 coefficient, increase reaction per 10 Activation 50 kJ mol−1, 59 mol−1 71 0–10, sublayers, respectively, indicating higher molecular-weight compounds resisting values significantly (p < 0.01) 10–30 (2.79 ± 0.10) than 0–10 (2.18 0.07) where less total stored most sensitive temperature. Cranberry could be used markers
