Hi. Can I use fire ash in compost as carbon? my compost pile is good and steamy, but too much nitrogen. Slimy and smelly. I would rather not use cardboard and news paper because they might contain glue and ink. Fire ash however, is very easy for me to get. We have wood fires frequently. We only burn wood from our pile and a fire starter at the center is all we use. If I collected ashes on the outside of it to use in compost, is this acceptable? I'm not trying to poison myself with my compost lol.
