Rob D. built this Micro-Bin system as a temporary test unit, which will become more permanent once the weather improves. He composts cow manure/bedding, chicken manure/shavings, and vegetable scraps. He uses the compost to help grow clover, alfalfa, comfrey, etc. Rob enjoys playing around with the compost mix and hopes to increase output of his finished compost product. He says he has turned into a "mad scientist compost guy".
