Did someone say inoculate? Fungi? Why yes, of course inoculation with fungi will help! Even plain old store bought mushrooms,
Agaricus campestris, will work on improving the cow poo. That's because they are also known as "meadow mushrooms", the kind that live in the soil that cows plop on. They aren't the best at detoxifying herbicides and pesticides, that would be your white rot fungi, but they can make some progress.
If you want to do a little better than store bought mushrooms, and add some diversity to the fungal species present, you need to go on a trek in the woods. Find old rotted logs and turn them over and scrape up any white stuff under them. That is white rot fungi and if you whiz that up in the blender and sprinkle it liberally over the MooPoo, you'll get some needed fungal decomposition going. It wouldn't hurt to add a little fresh pine bark or oak leaves. That's more lignin to feed the white rot fungus.
