But I've seen some people do some pretty funky things with anaerobic composting that adversely impacted the soil and created a dead zone for a couple of growing seasons. My hunch is that a big barrel of anaerobic goo was the reason why a friend's apple tree died. He dumped it out after it got so gross and stinky, and subsequently, everything around there seemed to die. He was making comfrey "tea", which was basically a big blue barrel that he kept packing with fresh comfrey leaves. It smelled like hell but he had read something on the interwebs about how great this stuff would be for his garden. It was so putrid that he decided to just kick the barrel over. Worse than just temporarilly sterilizing his soil, he created a dead space that lasted for the better part of two years.
