I planted flax for the first time this fall and I'm trying to think of what to do with the residue. My normal tillage it to mow, disc, plow then harrow twice. I'm not thinking that will work for flax straw. Perhaps I could chop it then no-till (disc type openers) if I could find one to rent or borrow. Burning is not an option due to proximity to houses. The field man says to expect about 45 bu/a on the flax. It will be going into wheat or grass hay within a couple months of harvest.
