Aerial seeding is a technique of sowing seeds by spraying them through aerial mechanical means such as a drone, plane or helicopter. When the purpose is reforestation, it is known as aerial reforestation. Aerial seeding is considered a broadcast method of seeding. It is often used to spread different grasses and legumes to large areas of land that are in need of vegetative cover after fires. Large wildfires can destroy large areas of plant life resulting in erosion hazards. Aerial seeding may quickly and effectively reduce erosion hazards and suppress growth of invasive plant species. Aerial seeding is an alternative to other seeding methods where terrain is extremely rocky or at high elevations or otherwise inaccessible. Problems with direct broadcast include germination, pests and seed predation by rodents or other wild animals. Transplanting seedlings from a plant nursery to the field is a more effective sowing technique. Aerial seeding has a low yield and require 25% to 50% more seeds than drilled seeding to achieve the same results. Aerial seeding is also often used to plant cover crops. Some plants often seeded by this method are perennial rye (Timothy, Red Fescue, Red Top, Bluegrass), Sudan grass, soy beans, buckwheat, hairy vetch, corn, cereal rye, winter wheat, oats, mammoth or medium red clover, sweet clover, berseem clover and crimson clover (Timothy). History According to the National Agricultural Aviation Association, the birthplace of aerial seeding in America happened 1921 in Ohio. Lt. John A. Macready, a U.S. Army pilot, used a modified Curtis JN-6 to dust a field of catapla trees with arsenate to kill sphinx moth larvae. This early crop dusting led to aerial seeding. Aerial reforestation, a type of aerial seeding, specifically to repopulate forest land after some type of disaster was being used as early as the 1930s. Planes were used to seed mountain areas in Honolulu that were inaccessible to traditional methods after forest fires. These experiments were largely unsuccessful, because of poor seed dispersal: seeds failed to obtain enough kinetic energy to enter the soil and as a result were massively predated. This in turn generated an infestation of rodents in Hawaii. By 1946 aerial seeding was being used in Oregon to seed more than 500 acres of Douglas fir, and Port Orford cedar as well as 100 acres of grassland and other trees that were burned by fire. In 1947 the Crown Zellerbach Corporation seeded over
