Hi, another Seattleite chiming in....I personally
take coffee grounds...and dump our own, straight into the compost bin or worm
bin and occasionally garden beds. Coffee grounds straight are ~ 3%
Nitrogen...which is pretty good.
The con: Coffee is acidic, and in our rainy
climate, we already have acid soil. So remember to lime your garden and
test it every once in awhile for pH.
While I think John Jeavons has a lot of good ideas
and think a closed system of gardening is ideal, using what would otherwise be
tossed into the landfill is a good thing too.
While I buy organic, shade grown, coop, ohhhhhh
soooo politically correct coffee from Cafe Mam, (http://www.cafemam.com/ismam.html)
I would be interested in finding out what kind of residue of pesticides in
standard coffee grounds. Starbucks, bless them, buys from small coops far
more than they label. I still don't buy there coffee, but I'll use their
grounds! If anyone has any studies specifically on coffee grounds and
chemicals...pass it along!
