Great question John.
I dont have any links persay, but books.
Gene Logsdon Small-Scale Grain Raising: An Organic Guide to Growing, Processing, and Using Nutritious Whole Grains for Home Gardeners and Local Farmers, 2nd Edition is really good for growing small plots of gain for a family.
The Back to Basics books are pretty good.
I think a lot of it has to do with the soil you have, how much compost you can add, your growing seasons. What naturally can grow in your climate? What container plants can you do?
