Rice husk biochar (RHB), produced from the pyrolysis of rice husk (RH), has a higher nutritious value than biochar made from wood. A field research was conducted to evaluate the short-term implications of RHB-derived nutrient translocation and distribution in rice crop, as well as their effects on soil nutrients, rice productivity, and methane (CH4) emissions in wetland Ultisol. The treatments included applying four organic fertilizers: rice husk biochar, daincha (Sesbania aculeata), jack tree (Artocarpus heterophyllus) leaves, and farm yard manure (FYM) at rates of 35 (N1), 70 (N2), and 105 (N3) kg N ha−1.
