I have access to a large amount of dog poop weekly (300 lbs?), poop from 20 horses in rough board and an unlimited suppy of wood chips from tree trimming. I want to use all of the dog poop, and will use as much of the horse poop and chips as needed. What type of setup/mix ratio would I need to effectively make compost that could be sold? Using all of the dog poop is the important part.
