http://www.goveganic.net/spip.php?article115 The link above takes you directly to the
online information sheets that they have developed. I highly recommend looking at the "chipped branch
wood section" which refers to making garden beds using woodchips. The full list of subjects they cover are:
Propagation and fertilizers
Growing beans for drying
Growing on clay soils
Garden Fungi FAQ
Gardening for wildlife
The vegan organic growers guide to beetles
Green manures
Chipped branch wood gardening
