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.

A shank for a seeder having furrow opening means at the lower end thereof for penetrating the ground to a desired level to form a main furrow, a sealer plate mounted on said shank above the bottom of the main furrow and trailing the leading portion of the furrow opening means, said sealer plate being below ground level with the shank at working depth and having wedge shaped side portions along opposite sides thereof with each side portion having surfaces that converge downwardly and which define edges that are to the exterior of the furrow opened by the shank, the edges also tapering downwardly in rearward direction, the side portions having facing surfaces on each of the opposite wedge shaped portions that taper toward each other in rearward direction, the side portions forming small auxiliary furrows laterally of the shank below the ground by packing the earth to provide a firm seed bed, said means defining spaced seed outlets on the shank for depositing seed in each of the auxiliary furrows.
