Fig. 1. Cumulative production of CO2 (a) and CH4 (b) in paddy soils with / without straw additions. The production in soils with straws was further partitioned as straw- and soil organic matter (SOM)-derived; rice straw mineralization (c) and its contribution to total CO2 and CH4 production (d) during the anaerobic incubation
The abbreviations “YT” and “CS” in the legend indicates Yingtan Red paddy soil and Changshu Wushan soil, respectively. The same as below
