What do you think is a more productive method of agriculture, 40 acres and a mule or 12 hectares and a burro?
In ag the word "productive" is quite expansive in definition. For ex; I raise tomatoes but store bought are cheaper in price but then add in the intangibles such as taste, safety, self satisifaction of raising one's own and the equation jumps in size. But then again I tend to side with the "hippie farmers" versus the agribusiness types anyway.
