Abstract: A helicopter mounts special dispensing containers, the dispensing containers supporting racks for stacking planting device transport and dispensing trays within which a series of planting devices are nested for discharge at an open end thereof. The planting devices constitute composite multi-section molded hollow cone bodies of powder molded urea-formaldehyde resin including one nutrient enriched section or band at the seedling side root area, the bodies carrying internally, a compacted growing medium within which is positioned a seedling either grown therein or transplanted therein. The bodies may bear a molded nose cone and may also bear by way of a collar, a propelling wing to increase the drive velocity of the body for forced penetration of the earth formation being planted. The individual planting devices are pushed from the planting device transport and dispensing trays at a rate depending upon the helicopter speed, altitude and planting density desired.
