As someone who spent quite a bit of his youth farming: these people are doing it wrong.<p>Hoeing weeds in a field that hasn't even been disced or planted yet? Sorting beans by hand? Planting wheat by hand? Fertilizing by hand? Digging ditches by hand?<p>That's some seriously medieval stuff. I'm sure it's traditional, etc, but it's not efficient, and it doesn't scale to large populations. I don't even want to think about what they aren't doing regarding soil chemistry, pest control, etc.
