Had to harvest corn in the mud. I am trying to no-till wheat with a Sunflower no-till drill, with new disc and all the down-pressure I can put on it, however I can't get penetration in the combine and grain cart tracks. It is still too wet to disc ahead of the drill, plus past experience has been that the drill won't shed the residue after disking. How much stand loss can I expect from seed on top of ground but under the residue?
