I have a property in the central west of New South Wales. The property run between two hills, one is mostly sandstone, the other is mostly shale. In a few areas there are exposed coal seams which have eroded to produce incredibly dark soils. There are large healthy Acacias and Eucalyptus growing in these soils.
I have been unable to find any useful infomation about soils of this type. I was wondering if there were any dangers associated with growing plants or running stock over these types of soils.
Im also interested in whether the coal or the dark soil would be a useful soil ammendment similar to biochar.
