简介
Highlights
- 3D image analyses of biochar showed pore diameters 2–11 μm dominated pore space.
- Plant tissue structure controlled the pore structure of biochars.
- Biochar affected moss moisture in regions relevant to plant-available water.
- Biochar partly acted as an isolated unit lacking contact with adjacent growing media.
- Quantifying biochar structure was needed to understand its water retention impacts.
Amending growing media with biochar has the potential to sequester carbon and enhance the properties of the receiving substance. However, knowledge of the mechanisms of how biochar amends the physical properties of the material is incomplete. By combining 3D image analysis and more conventional methods, this study aimed to (1) characterise the pore structure properties of three different plant-based biochars and (2) quantify their impact on Sphagnum moss growing media physical properties. The 3D …
