That isn't too far off inland prices, being in BC that should mean you get 2 crops a year while in AB you get one heavy one or 2 light ones.
The price isn't enough as the missing data is how many bales per field size is missing. Foreign owned has never been a good deal for the locals be it hay or anything else that you would find on plantations in Central America. Just because the customers are the US you can bet it is done on the cheap.
Hay and grazing animals is the best and cheapest way to upgrade marginal soil into something more productive, especially if that area sees a slight increase in moisture in the summer months, if not then winter rains have to be diverted into aquifers to be used in the drier times.
It seems the land is determined to be for hay export that goes to the owners of the land, good luck in trying to break that cycle.
