Soil Colloid Type |
Name one defining characteristic of this colloid |
Where in the soil profile will these colloids dominate? | What soil order would contain a large amount of these colloids? |
|---|---|---|---|
| Crystalline silicate clay (1:1) | |||
| Crystalline silicate clay (2:1) | |||
| Noncrystalline silicate clay | |||
| Fe and Al Oxides | |||
