For one, big barley is more powerful than big alfalfa
I don't know the numbers, but I do think a lot of barley/wheat crops in Utah and Idaho are dry farmed. The yield sucks, but it's cheaper for obvious reasons.
Also, we seem to be the only culture actively trying to make it uncool to grow more fruits and vegetables with less. Give me the most GMO ****ing orange you can. I want the orange the size of a canteloup. I want my lime the size of an orange. Not this shitty organic lime that is hard as a rock and looks like it has a diaper rash.
Also, GMO cows. We need bigger, steakier, more drought tolerant cows. Like a bovine matrix is what I'm picturing here.
I've seen a bunch of articles about those grass grow-houses (not that kind of grass you hippies) that are able to produce a ton of feed for livestock, year round, from a really small foot print with only a fraction of the water. This has to be the future...maybe the government should subsidize that technology and those builds instead of just paying farmers to fallow their crops?
