Warming may weaken biochar’s climate benefits in cropland soils, global study finds

A new global analysis suggests that biochar's ability to store carbon in agricultural soils may be overestimated due to increased carbon dioxide emissions from warming. The study found that warming significantly increased CO2 emissions from biochar-amended soils by an average of 77%, with effects strongest in croplands.

Study reveals soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies

A new study led by Prof. YAN Xiaoyuan finds that most nitrogen gas emissions from rice paddies originate from soil organic nitrogen, rather than applied fertilizers. The researchers propose a novel mechanism to explain this phenomenon, suggesting that fertilizer activates soil nitrogen pools, indirectly driving larger nitrogen losses.
