Switchgrass is a native prairie grass. It grew back in the days when the buffalo roamed. It's drought resistant, sends its roots down six feet, grows six feet tall, and is really thick and really dense. If you were looking at straw yields of a tonne an acre, you'd be looking at switchgrass yields of anywhere between three tonnes and six tonnes an acre. Because it's drought resistant, farmers like it because, hey, you don't have to worry about irrigation.
We have a plot of 100 acres of switchgrass growing up here in Renfrew County. We decided that we would like to grow some ourselves and run it through our demo plant and test it. Yes, it grows great in Renfrew County too. It doesn't have to just be a prairie grass. It's a wild grass with a very high yield.
