Abstract
A unique and improved seed and fertilizer coulter-type drill is disclosed. The drill has a plurality of coulter wheels in four rows, the front two rows of coulters cut first furrows and deposit seed. The rear two rows of coulters cover the seed in the first cut furrows and produce a second set of furrows in which fertilizer is deposited, approximately 1 inch away from the seed. The two sets of coulters are followed by a plurality of press or packer wheels which ensure good seed to soil contact and cover the *remaining fertilizer furrows.
