Rice husk and melaleuca biochar additions reduce soil CH ₄ and N ₂O emissions and increase soil physicochemical properties.

ABSTRACT: Background: Biochar is a promising material in mitigating greenhouse gases (GHGs) emissions from paddy fields due to its remarkable structural properties. Rice husk biochar (RhB) and melaleuca biochar (MB) are amendment materials that could be used to potentially reduce emissions in the Vietnamese Mekong Delta (VMD). However, their effects on CH ₄ and N ₂O emissions and soil under local water management and conventional rice cultivation have not been thoroughly investigated. Methods: We conducted a field experiment using biochar additions to the topsoil layer (0-20 cm). Five treatments comprising 0 t ha ^-1 (CT0); 5 t ha ^-1 (RhB5) and 10 t ha ^-1 (RhB10), and 5 t ha ^-1 (MB5) and 10 t ha ^-1 (MB10) were
