Abstract: The southern lowlands of Brazil, characterized by hydromorphic soils suited for flooded paddy rice, play a key role in food security. In recent years, rice-soybean crop rotations have been adopted to improve system profitability and sustainability. However, their implications for greenhouse gas (GHG) emissions lack sufficient investigation in subtropical conditions.
