As I have never seen an analysis of compost before these figures don’t mean much to me, hopefully somebody else might be able to give you a more qualified answer. Here, in Switzerland, we can also get compost that are the leftovers of biogas production, it sounds much like yours. I usually mix it with horse manure and leave it to compost some more for at least 6 months before using. I’m not sure how much, if any, good it does, the only positive effect I’ve noticed is that after spreading a good layer there are hardly any slugs, they don’t seem to like it.
