Pneumatic metering of hardwood tree seeds


, : Pneumatic metering of hardwood tree seeds. Applied Engineering in Agriculture 6(2): 239-243

A commercial, no-till row drill was extensively modified for use in direct sowing of hardwood tree species in surface mine reclamation. A pneumatic seed metering system was designed, fabricated, and mounted on the drill. The metering device was tested under laboratory conditions which simulated varying terrain slope and field speed with seeds of various hardwood tree species. Metering efficiencies of 97% were achieved for pin oak seeds at 3.2 km/h and 50% slope.
