However, the demand for baled wheat straw (usually in rounds) is still quite good because cattle farmers and dairy operators use wheat straw with the addition of other grains in their tub grinders to make feed. Tub grinders aren't just for shredding old tires... Wheat straw in rounds is easily introduced into a tub grinder. Like I said previously, one guy down the road does nothing but round bale wheat straw in net and sells it to local cattle ops and dairy ops. He's especially busy in the winter months delivering it by the semi load. He contract bales everything, owns very little ground himself.
