It is not the usual bad
compost smell, like hydrogen sulfide or ammonia. Instead, it is the woody forest floor smell that a good pile is supposed to have, but so strong it can be smelled 200 feet away quite well, and we have to keep the windows shut. The pile is made of weeds and dead plants, not kitchen scraps or manure, with some soil, a bit of blood meal, and some gypsum added. It is maybe three cubic yards or less.
