- •
Biochar of various particle sizes was applied to light-textured tropical soils.
- •
Biochar increased aggregate stability more strongly under soybeans than under maize.
- •
Percent stable soil aggregates levelled off at high biochar content of aggregates.
- •
Biochar altered soil pore-size distribution causing an increase in available water.
- •
Biochar reduced soil bulk density due to soil aggregation and weight dilution.
