> Pigeon Towers: A Low-Tech Alternative to Synthetic Fertilizers This only works if you like perpetual motion machines. They feed off the grain in the fields so they are not going to give back more from the fields than they take. But they do turn grain into meat, eat pests, sold for status symbols and racing, and most of all are a important part of a nation identity. I'd like to see a proper study but 100% doubt they could be used to increase yields in itself and while we destroy native lands for farming we must use it at as high a levels as possible. I suspect even when land was less intensively farmed 1000 years ago their status (Google for pics, they are impressive and not just Iran) and liking meat was still what made them viable, not crop yields. I also suspect they are just a sneaky way to steal from you neighbours, this is what is more interesting.
