Principal Binding Agents | Soil Texture | Dispersion | Slaking | Dispersion Animation
Model of soil aggregation from Tisdall and Oades (1982). Principal binding agents at each level are:
B: plant roots, fungal hyphae; with short- to medium- term persistence.
C: decayed roots and fungal hyphae; with longer-term persistence.
D: microbial remains and humus; with longer-term persistence.
E: adsorbed humic substances, hydrous oxides; with very long-term persistence
