A seeder to sow progeny test tree seeds in nurseries was developed by the USDA Forest Service's Missoula Technology and Development Center. The four- wheel, pedal-driven vehicle punches 96 dibble holes into the soil. A shutter- type tray then sows seeds simultaneously into each dibble hole. The seed trays are filled before field sowing. Because covering the seeds was not incorporated into the design, seeds must be covered with dirt or grit using a spreader or by hand. The seeder was developed as an alternative to the current labor-intensive plywood board sowing method.
