•Woodchip biochar improved chemical and hydraulic properties of 2 soils.•Improvement is commensurate to amount of added biochar.•Interparticle bonding and resilience of aggregate was enhanced up to ≤50gkg−1.•Amendment rate beyond 50gkg−1 did not make additional useful impact. The potential benefit o...
