Airplane-seeding of wheat has been increasing since its start in 1965 in Fulton County, Kentucky. Over 20,000 acres were seeded in the fall of 1968, with the acreage concentrated in the Purchase and Bowling Green areas.
Farmers report these advantages for aerial seedings: (1) early establishment of small grain; (2) similar seeding cost as compared to drilling; (3) labor use in normal seeding operations diverted to other farm operations.
