I've done a good bit of research in the past year on sustainable farming and permaculture and I really believe that it has, not only the benefit of being good for the earth but can also provide a good income or at least a very good second income to anyone with a couple acres and some ambition. A few years ago I would have been satisfied with $5000-6000/acre of off a market garden but I really think now that there is a lot more potential. If your not familiar with permaculture it involves putting all of the waste back into improving the soil for the future. One of the setbacks that I've experienced in the past couple years has been to have enough compost to make a difference in the soil for a 2 acre market garden. I use everything that I can compost around here and get some extra from a nrighbor with a landscape business but so far it's been a pretty small amount. About a year and a half ago I added a few chickens and recently increased the flock to 20. In my opinion, chickens are the ultimate composting machine along with providing eggs to eat. Now 20 chickens are still only going to add about 600lbs of fertilizer/year but I really think 2 acres can support a much bigger and still healthy flock of chickens especially if it includes broiler chickens a couple times/year. And that is what permaculture is all about, having a plan to use the land in the most efficient and sustainable way. Stay tuned for more thoughts on this and see where this project is headed.
