Aerial seeding helicopter Aerial seeding from a Hughes 500 helicopter. 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. [1]
The first known aerial application of agricultural materials was by John Chaytor, who in 1906 spread seed over a swamped valley floor in Wairoa, New Zealand, using a hot air balloon with mobile tethers. [3] Aerial sowing of seed still continues to this day with cover crop applications and rice planting.
The aerial spread of fertilizer has also raised concerns, for example in New Zealand fertilizer entering streams has been found to disproportionately promote growth of species that are more able to exploit the nutrients, in a process known as eutrophication, which has led to restrictions on topdressing near waterways.
The primary types include soil seed banks, which are found in terrestrial environments; wetland seed banks, located in aquatic habitats; and canopy seed banks, present in the upper layers of forest ecosystems. [2] [3] Each type of seed contributes uniquely to plant biodiversity, ecosystem resilience and human well-being. Also, they are unique ...
In 1964 the first aerial seeding was carried out in logged areas of Alpine Ash using a small Cessna 180 fitted with two wing pods which each carried about 100 kg of seed. Because the seed was so fine it needed to be bulked up into a small seed ball about 2 mm across by coating with kaolin clay and using mucilage as adhesive. Sometimes small ...
Aerial topdressing is the aerial application of fertilisers over farmland using agricultural aircraft. It was developed in New Zealand in the 1940s and rapidly adopted elsewhere in the 1950s. The Auster Agricola , a specialist aerial topdressing plane A PAC Cresco plane with the fertiliser emerging from between the wings.
Alan Marcus Prichard (15 November 1907 – 2 November 1986) was a pilot for the New Zealand Public Works Department from the late 1930s to mid-1950s. Using a Miles Whitney Straight from 1939 on his own initiative and sometimes forging aircraft log books to conceal his work, Prichard conducted trials of aerial seed sowing and spreading fertilizer which ultimately led to the development of ...
Planetary engineering encompasses a variety of methods such as terraforming, seeding, and geoengineering. Widely discussed in the scientific community, terraforming refers to the alteration of other planets to create a habitable environment for terrestrial life. Seeding refers to the introduction of life from Earth to habitable planets.
