Your seed bed should be fine firm and moist for your red (crimsom) clover (I guess thats what your planting.) . It usually broadcast at a rate of 15 to 20lbs per acre hulled or 45 to 60 unhulled (but im sure you knew that). I suspect it could be used as a green maunure. I would disc plow to to eliminate competiton from weed growth.
The growth of clover is improved by mowing the stubble and removing any grain crop immediately.
