Abstract
A furrow opener shank for use with seeders has seed outlets and fertilizer outlets at the lower end thereof, and includes a sealer plate which will permit the depositing of anhydrous ammonia or liquid fertilizer in a deep furrow and which positively seals the furrow prior to depositing the seeds in the furrow. The sealer plate has wedges that form a pair of grooves or small furrows spaced laterally of the center line of the furrow to provide pockets for the seeds being deposited. The shank has dual outlets for seed at the lower end so that seed is deposited in each of the furrows that are being formed by the sealer plate to keep the seed separated from the fertilizer to insure good germination and rapid growth as well as insuring placement of the seed in regions that are most likely to have moist soil.
