“primitive” farming

I was reading through a text book for one of my other classes and came across some interesting data. The author summed together the total amount of kilocalories for an input-output ratio, comparing a “grass” farmer to a corn farmer. The grass farmer produced a ration of one to eleven – that is for every kilocalorie expended, eleven were produced. The corn farmer, using modern machinery, herbicides, insecticides, fertilizers, transport and irrigation, produced a ratio of only one to 3.5!
