Comparison of a Drill-type Seeder and a Vacuum-Drum Precision Seeder in a Virginia Loblolly Pine Nursery
A 3-year study compared root collar diameter distribution and cull percentages of loblolly pine (Pinus taeda L.) sown with either a drill-type seeder (Whitfield) or a vacuum-drum precision seeder (Love). Seedbed densities were similar for each machine. Although the precision seeder distributed seed more evenly, no consistent improvement was seen in uniformity or cull percentage with its use.
