Note: I am not affiliated with this site nor it's owner, but I found the information in his video very helpful.
It's starts out a bit slow, but goes into actual dollars and cents detail about how he earns his income, how much he makes per plot of land, how much he grows and where he sells it. I have been looking for examples like this to model my farm after in order to produce a consistent product selection at a marketable price. He is farming on relatively small plots of land (comparable to a normal suburban backyard) and producing a respectable income doing so. Well worth the 42 mins to watch.
I'm not growing for market, but it sounds like this might have applications for figuring production in a home garden also. I'll try to watch later today, but I'm commenting now in the hopes that prospective market gardeners who missed this the first time will have time to see it on the weekend. Thank you for sharing.
