Abstract
Abstract A seeder foot is shaped to open a furrow and to facilitate immediate initial filling thereof as soon as the foot has passed. A plurality of feed tubes are situated immediately behind the foot, one above the other, with the lowermost one extending rearwardly more than the next succeeding one and the next succeeding tube extending rearwardly further than the tube thereabove. These tubes are vertically spaced apart thus enabling a layer of soil to cover the material discharging from the tubes so that the layers of soil separate the materials one from the other. The lowermost tube may discharge granular or liquid fertilizer, the next tube may discharge seed grain and the uppermost tube may discharge a granular herbicide.
