ScienceReturning straw to paddy fields may help soils store more carbon
Returning straw helped increase soil organic carbon in an 11-year paddy-field experiment, according to a post citing a 2026 study.
TLDR
A post citing a 2026 study in Agricultural Ecology and Environment describes two ways carbon was retained when straw was returned to paddy fields. Some was protected within soil aggregates—clumps of soil particles—while some became chemically linked with iron oxides, making it more stable. The post highlights how carbon retention depends not just on adding organic matter, but also on biological and chemical processes in the soil.
