Biochar has attracted considerable interest because of its potential influence on soil structure, porosity and water dynamics.
Depending upon its origin and production process, biochar may improve soil aeration, contribute to water retention and provide additional habitat for beneficial microorganisms.
Its hydraulic behaviour varies significantly according to feedstock, pyrolysis conditions and particle characteristics.
For this reason, biochar cannot be treated as a universally predictable engineering material.
Future evaluation within Radixora should consider both its hydraulic contribution and its interaction with other engineered soil improvements.
