Hi Helen,
Thanks so much for your book! I got it as soon as I read about it here and am enjoying it very much. I have experienced the same about stepping back and letting nature balance out with a little help from me in the way of planting. But I would not have been able to express it so well!
Kate, with regard to growing grain, you might also want to check out Ecology Action's Booklet 33 on growing grains on a small scale here:
http://www.growbiointensive.org/ePubs/ They're in Willits CA and have done a lot of research using bio-intensive methods. The booklet is from 2005 but should still be relevant.
I'm sure this book will help us all shift our mindsets more in the direction of working with nature and stewarding the land we have influence over!
