Soil organic carbon mineralization in response to changes in soil moisture and temperatures increasing in two long-term experiments in France

These data sets represent measurements made during incubation experiments in the laboratory. The aim of these experiments was to assess the sensitivity of carbon stored by agroecological practices to extreme climatic events such as changes in soil moisture regime and increases in temperature. To do so, we monitored soil carbon mineralization from two long-term experiments where agroecological practices have been implemented since 1998. These datasets present incubation measurements including daily absolute carbon mineralization (in µg Cmin/ g dry soil/ day), cumulative absolute carbon mineralization (in µg Cmin/ g dry soil) and cumulative specific carbon mineralization (in µg Cmin/g.SOC). Moisture treatments tested: WET represents a continuously wet scenario at pF 1.5; MWET a continuously moderated wet scenario at pF 2.5; DWC represents a dry-wet cycles scenario and DRY a continuously dry scenario at pF 4.2. All moisture treatments were incubated at same temparature, i.e., 20°C. For temperature, the soils were incubated at either 20°C, 28°C and 35°C. All temperature treatments were maintained at the same moisture, i.e., pF 2.5. Agricultural practices concerned in the Cage experiment: CON-LC represents the conventional agriculture; ORG represents the organic agriculture and CA represents the conservation agriculture. Agricultural practices concerned in the QualiAgro experiment : CON-QA represents the conventional agriculture without organic inputs MSW represents the Municipal solid waste compost; BIOW represents the biowaste compost and FYM represents the Farmayard manure.
