Soil compaction occurs widely in modern agriculture, leading to reduced crop yields and enhanced soil N2O emissions. Biochar, an emerging biomass-pyrolysis product with porous structure, is hypothesized to alleviate soil compaction problems. A field mesocosm experiment involving biochar addition and...
