A method and apparatus for discharging material at spaced intervals each provide a conveying tube and a conveying mechanism for moving material from a first end of the tube toward a second opposite end. Discharge openings are provided spaced along the tube at different heights thereon. Openings near the first end are at a higher elevation on the tube than those near the second end, corresponding to downward slope of material upon initial entry and conveyance within the tube. The decreasing elevation of discharge openings and corresponding slope of material act to delay discharge near the first end, by requiring a build up of material height to reach the opening, and hasten discharge near the second end, by eliminating the need to fill drop tubes or metering devices before conveying material further along the tube. This reduces lag time between progressive discharge openings thereby providing more even material distribution therefrom.
