原始语种摘要: Abstract(#br) Purpose(#br)Biochar application is deemed to modify soil properties, but current research has been mostly conducted on the degraded land in tropical regions. Using six consecutive years of biochar field trial, we investigated effects of biochar on soil aggregates, structural stability, and soil organic carbon (SOC) and black C (BC) concentrations in aggregate fractions. The findings have important implications in managing soil structure and SOC sequestration in high fertility soils of the temperate areas.(#br) Materials and methods(#br)The study had four treatments: control; biochar rate at 4.5 (B4.5) and biochar rate at 9.0 t ha −1 year −1 (B9.0); and straw return (SR). Soil samples were collected from 0–10-cm layer, and aggregate size distribution was determined with the...
