A seeding apparatus having a distribution manifold with selectively openable outlet ports thereon, to permit or stop delivery of seed or fertilizer to soil A meter device, responsive to both the number of selected open ports and the speed of the apparatus over the ground, is provided to regulate supply of seed/fertilizer to a distribution manifold. The distribution manifold has a plurality of outlet ports spaced about a periphery of such manifold, each outlet port having a valve to allow opening and closing of individual outlet ports. Soil engaging members on such apparatus are individually raisable from an lowered operative position to a raised inoperative position, and when moved to such inoperative position, valve associated with an outlet port for providing seed and/or fertilizer to such soil engaging member is closed to prevent supply to the associated soil engaging member.
