Farmers get a ridiculously small percentage of the retail price on food. The price per pound in a store is usually comparable (same order of magnitude) to the wholesale price per ton.
The production cost for this tech is probably at least 10X traditional farming. It makes no sense because we have too much food. The biggest nutritional problem in society is obesity and we burn 1/3 of our corn crop on ethanol and feed a good part of the rest (and soy) to cattle and pigs because there is nothing else to do with it.
