http://1greengeneration.elementsintime.com/?p=1077 Here is a good soil amending list for anyone interested in getting more detailed info. Please keep in mind the transportation distance of some of these. We live in a rich environment full of kelp, shell, urban compost (coffee grounds, leaf litter, nettles, comfrey etc. if you make it from your local environment you are entering into a deeper relationship with the land around you.)

This one is a treasure trove of info- especially relevant to the PNW

If you're following the soil amending links check out the do-it-yourself local calcium amendment - very relevant to OB gardeners or anyone else gardening in heavy clay-rich soils. And if you don't want to take your pH too basic from the oyster shell additions, you can add coffee grounds. Check your acidity levels first.
