Earlier quoted context omitted.
The number is high, but farming in generally is a high risk bet. I often say to people, I need to spend (i.e risk) $100,000 for the chance to make $20,000-$30,000 if everything goes correctly. One major event and you just lost 100K. Scale up or down depending on the size of the farm.
Sustainable farming is a terrible business as long as giant unsustainable factory farms are a thing. If you want to make money farming, you need to either go the vertical integration or agro-tourism route.
Not trying to refute what you are saying because I honestly don't know, but this seems to contradict the original article. Of course sustainable/organic farming is going to struggle to compete in the normal international commodities market, but in the article it mentioned that organic grain could be sold directly for 2-3x the base commodity price. Seems like that kind of progressive price scale might make it not such a "terrible business".
