Long-Term Biochar Application Enhances Carbon-Phosphorus Costabilization and Mitigates Methane Emissions in Flooded Rice Systems.
Chen H, Xu J, Yuan J, Wang L, Chen G
Summary
PubMedA 13-year field study found that adding straw-derived biochar to rice paddies improved how the soil stores carbon and phosphorus while reducing methane emissions, suggesting biochar could help mitigate climate impacts in major rice-growing regions.

Original Abstract
Biochar is increasingly promoted as a climate-smart amendment, yet its long-term effects on nutrient retention and greenhouse gas emissions in flooded rice systems remain poorly resolved. Here, we combine a 13 year field trial with graded straw biochar applications (0-22.5 t ha

Species Mentioned
Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
