Not that I can think of!
Coal ash can be acidic or alkaline, based on the properties of its source coal. I'd be leery of using it in a garden because it can contain a number of heavy metal byproducts. It is considered quite a source of environmental pollution.

it is much richer in heavy metals than wood ash. I think I could use it in the lawn, under trees or in the flower beds, but not near a fruit tree or vegetable garden.
No
What about leonardite? Is that a good substrate for plants?
