Soil biota, carbon cycling and crop plant biomass responses to biochar in a temperate mesocosm experiment

Biochar addition to soil is a carbon capture and storage option with potential to mitigate rising atmospheric CO2 concentrations, yet the consequences for soil organisms and linked ecosystem processes are inconsistent or unknown. We tested biochar impact on soil biodiversity, ecosystem functions, and their interactions, in temperate agricultural soils. We performed a 27-month factorial experiment to determine effects of biochar, soil texture,...
