22 Black, grey and yellow gradational (earth) soils on Neogene marl
| These soils mainly occur in the south-west of the CMA where dissection of the landscape has exposed marl deposits (Gellibrand Marl). This area has a higher rainfall than the basalt plains to the north and north-east. There are minor occurrences on the Bellarine Peninsula. These soils include medium to heavy textured earths, both weakly and strongly structured, as well as the occasional shallow calcareous soil. They are deep (>100 cm) pale soils with a bleached subsurface horizon and mottled light to medium or medium to heavy clay subsoil, and are often strongly acidic with some calcareous material with depth (>100 cm). Notable characteristics are the gradational nature of the profiles with heavy subsoils, acidic upper soil and alkaline (calcareous) lower subsoils, indicating a leached soil environment. |  |
