    Abstract: A furrow opening point 40 is described for attachment directly to the seed boot of a hoe type seed drill between the split packer wheels. The furrow opening point 40 has an elongated body 50 that extends from an upper fertilizer receiving portion 56 to a bottom edge 54 of the soil engaging portion 52. The soil engaging portion has an upper section 61 and a lower section 62 for forming a two-tier furrow. A liquid fertilizer passageway 90 extends downward through the elongated body to the bottom edge 54 for dispensing liquid fertilizer at the base of the furrow. A dry granular fertilizer passageway 96 extends downward through the elongated body to a bottom surface 84 for dispensing dry granular fertilizer down a vertical channel formed along the trailing face 80 to the base of the furrow. A leveling section 100 forward of the seed opening 30 levels and firms the soil in the upper portion of the two-tier furrow to form a good seed bed.
