I often wonder on small acreage of these niche crops , what you do if it’s not a lorry load or you’re left with 2-3 tons that won’t go on a lorry .Linseed is an up and down crop here. One year a ton to the acre and the next year 5 cwt.
Lupins did well though late harvest, wet. Good break for wheat, but limited market and expensive seed. They don’t like chalk.
