The majority of farm production in the US is from factory farms
. Most small farms
now would hvae been considered factory farms
not that long ago. Farm production due to actual small farmers is minuscule and is not profitable. Probably the largest small farms
around would be Amish or Hutterite or Old Order Mennonite. We could see what they are doing.
In Germany there used to be many small farms
through the 80's. Agriculture in Germany was based on the small farmer. I have no idea how many have survived. Through the 80's they primarily used manure as fertilizer. So agriculture that can feed 80 million people can be based on small farms
and not use environmentally hazardous techniques. Organic farmers are however a minority in Germany as elsewhere. Organic farming probably can't feed the world now.
