Curiosity here ... how can a stump and all-round killer (from what you
say) be sold instead as a compost accelerator? I wouldn't put (for
example) creosote into my heap!

It's rich in nitrogen when it decomposes, hence accelerating compost
breakdown. http://en.wikipedia.org/wiki/Ammonium_sulfamate

Ahhh! Thanks.
