Fair enough, but the phosphorus has to be delivered to a farm (either before or after being combined into a fertilizer), and that's done with a truck, right? Are you arguing that the total transportation cost of the phosphorus that eventually gets it to the farm where its used is going to be much less $100/ton? Separately, what term other than tractor trailer should I use to sound cool?
