The Intelligent Gardener by Steve Solomon & Erica Reinheimer is the best single volume reference on soil minerals for the home gardener. If you want to learn why and how to balance your own soil, this is the place to start.
Weedless Gardening by Lee Reich covers intelligent irrigation systems, as well as mulching and raised beds.
Advancing Biological Farming: Practicing Mineralized, Balanced Agriculture to Improve Soils & Crops by Gary Zimmer is geared to farmers, but has much excellent information in it.
The Farm as Ecosystem, by Jerry Brunetti is also aimed at farmers, but if you really want to understand how all the pieces work together, this is the book to learn it from.
