Effects of Iron-Modified Biochar on N2O Emissions and Nitrogen-Cycling Microbial Potential During Laboratory Incubation of an Alkaline Loess Soil
Alkaline agricultural soils pose a significant challenge for N2O mitigation. Iron−modified biochar (FBC) holds potential for greenhouse gas reduction, yet its mechanisms in alkaline soils remain poorly understood. This study focused on alkaline loess in Yan’an, Shaanxi, and established three treatments (CK, BC1%, FBC1%...
