We did flax this year, wasn't the greatest as you express but at least we are trying things. Canola and Wheat? Like the worst combination for disease in your soils? I personally don't even understand why we grow wheat, it costs so much and is worth so little. We are slowly gaining more oat acresYou don't want to grow flax, its terrible. There's the straw thing and seeding next year, stuff wraps. Yields are terrible and the price is so low and inputs so high.
You definitely don't want to grow flax, keep growing canola and wheat.
