A furrow opener and press wheel for an agricultural implement to place fertilizer and seed at different depths in soil has replaceable abrasive resistant plastic side plates and a press plate to avoid soil build up and plugging of fertilizer discharge openings. The lateral distance between the side plates is adjustable so that seeding width can be changed. A seed divider attached to the furrow opener separates the seed into lateral rows on opposite sides of a band of fertilizer placed in the soil below the press plate.
