I only fertilize what I'm going to cut for hay. I do try to move my hay fields around. If there was enough hay here for me to buy, I wouldn't even fool with hay. I've got some crab grass, that I hit with a little N along the way, as long as we're getting rain. I hadn't fertilized my fescue pastures in a long while. I'm stocked at about a cow calf pair per acre and a half of pasture. If it's a wet year, I seem to have enough grass. If it's a dry year, I'm usually glad I didn't fertilize.
