I found this really great blog post by a guest writer on Jeff Fowle's blog. This writer recounts her time growing up on a farm and how she and her husband bought a farm to raise their children on.
She also talks about the importance of teaching children about agriculture. She refers to a book that has 100 ways to help kids get involved in ag. This book is written by a child advocacy expert who examines the current separation of kids from the outdoors, and concludes that it has caused a lot of childhood problems. This is a book I'd be interested in reading!
