Chromosols are found throughout Tocal in all the paddocks that contain Kurosols. We find that they are similar to Kurosols and Sodosols in that they:
- are problem soils
- are found on rolling slopes and crests and on old high terraces
- have parent material of weathered sedimentary rocks - sandstone/conglomerate
- support native vegetation of spotted gum forest
- can show dramatic increase in productivity with high inputs.
Chromosols differ from Kurosols and Sodosols in that they are not strongly acid down the profile and are not sodic.
