FARMS!!!!!!! :)

Farming and Food Production

•Subsistence- variety of mixed crops, extensive use of human labor, low input for fossil fuels, chemicals and capital.
•Commercial- single crop, maximum yield, high levels of technology.

There are different classifications of farming:

Energy budget farming

•Examine inputs, outputs, flows and storages in order to determine this.
•Consider marketable product, which is only % of total output
