None:
Non-continuous flooding (NCF) in rice was recently reported to improve the field-scale, seasonal carbon balance. In this response article, we clarify our system boundaries (seasonal, field-scale), address the role of yield carbon and microbial indicators, and add sensitivity checks with expanded data. Across these checks, NCF consistently reduces methane without penalizing yield, supporting our original conclusions.
