Liu et al. (2024): Soil carbon sequestration increment and carbon-negative emissions in alternate wetting and drying paddy ecosystems through biochar incorporation

Chang Liu, Taotao Chen, Feng Zhang, Hongwei Han, Benji Yi, Daocai Chi IN: Agricultural Water Management, 300, 108908, https://doi.org/10.1016/j.agwat.2024.108908

How biochar incorporation converts rice paddy into carbon negative and enhances soil carbon sequestration (SOCS) remain largely unexplored, especially under alternate wetting and drying irrigation (I_AWD). A 3-yr field experiment was conducted utilizing a split-plot design with continuous flooding irrigation (I_CF) and I_AWD as main plots and two biochar incorporations at the rate of 0 t ha⁻¹ (B₀) and 20 t ha⁻¹ (B₂₀) as sub-plots.
