Rotational grazing and perennial pastures

"...one of which is sorghum sudan grass, and if you don't mow that, it gets to be like ten feet tall. And so we had pigs that were  running through there, that reminded us of the velociraptors in Jurassic Park–you know, you can't see the animal, you just see the top of  the plant waving back and forth. And so we were always on safari when we had to go out and do pig chores."This week on the show, we visit Nightfall Farm, a livestock farm in Southern Indiana focused on sustainable agriculture.We talk about perennial pastures, rotational grazing and what farmers can learn when they listen to their animals.
