Published: Dec. 7, 2023

Abstract Biochar, widely recognized for its capacity to counteract climate change impacts, has demonstrated substantial benefits in agricultural ecosystems. Nevertheless, empirical studies exploring efficacy during climatic aberrations such as heavy rainfall are limited. This study investigated the effects of compost and biochar addition on corn growth attributes, yield, soil CO 2 N O fluxes under rain (exceeding 5-yr average) waterlogging conditions. Here, treatments included (CP, 7.6 t ha −1 ); rice husk (RB, wood (WB, control (Cn). Under high waterlogging, CP treatment manifested a pronounced enhancement biomass productivity, exceeding productivity Cn by 12.6 32.2%, RB 120 195%, WB 86.1 111%, respectively. Corn yield increased order: > RB. Intriguingly, negligible disparity occurred between straw grain index, but both recorded distinctively lower values than treatment. Also, remained largely similar two Overall, straw, whereas biochars reduced flux waterlogging. Although derived from short-term experimental window, these pivotal findings furnish invaluable insights devising amendments environmental contexts extreme perturbations. Our offer robust foundation refining nutrient management strategies confronted with challenges, long-term necessary definitive conclusions.
