Abstract: A method and apparatus for improved agricultural seeding; especially useful in no-till direct seeding. In the illustrated embodiment an inclined furrow is cut with a rotating disk that is inclined with respect to the vertical and the horizontal; the furrow has a raised lip, and straw and the like stalks are cleaved during the cutting. Seed is inserted by known means, and then a packer wheel, preferentially inclined in vertical and horizontal directions opposite to those the disk is inclined, runs across the lip and closes the furrow. Advantages include substantially reduced energy required for the furrow cutting, less weight required on the furrowing disk, more even seeding depth, less hairpinning, less soil disturbance, and less weed seed burial.
