Buffalo Bird Woman was a Hidatsa Indian born in 1839. This book is her reminiscences about the gardening of her and her tribe. She describe their gardening practices and the tools they used but also shares her memories of her youth and the traditional tools used by her elders. This is an excellent resource to understand traditional Native American agriculture.
This is an excellent book, especially because of how it is transferable to forest gardens as opposed to traditional gardens. Her methods are no-till and focus on the use of mulch. I found her methods made a significant difference in forest gardening, especially because it requires much less water.
The full title includes the phrase, "an introduction to natural farming." This man revolutionized farming when he started to question the modern farming methods. He created a whole, natural and no-till form of farming. He started with rice, but went on to try other crops and orchards. This is excellent information for non-traditional farming.
Carol Deppe builds on her "wake-up call" during Y2K and climate change to look at how to garden staples reliably. She pulls together a lot of things that could make or break a garden in the future: soil quality, water, fertility, labor, etc...and also has a great approach to nutrition, seed-saving, and food storage.
The book starts with general information about seed selection, soil temperatures, use of compost and mulch and other helpful information on growing were the growing seasons are shorter. He includes chart for plant spacing, which plants to partner and when to plant and harvest. The last half of the book speak to individual vegetables so you can get more specifics on the plants you want to grow. A well done book, written from the authors practical experience.
