Alan Prichard
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 aerial topdressing 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. Origins Previous aerial applications The first k .... References *Alexander, G. & J. S.

New Zealand Ministry Of Works
The New Zealand Ministry of Works and Development, formerly the Department of Public Works and often referred to as the Public Works Department or PWD, was founded in 1876 and disestablished and privatised in 1988. The Ministry had its own Cabinet-level responsible minister, the Minister of Works or Minister of Public Works. Historically, the state has played an important part in developing the New Zealand economy. For many years the Public Works Department (which became the Ministry of Works in 1948 and the Ministry of Works and Development in 1974) undertook most major construction work in New Zealand, including roads, railways and power stations. After the reform of the state sector, beginning in 1984, the ministry disappeared and its remnants now have to compete for government work. The Ministry of Works and Development was disestablished in 1988 and a Residual Management Unit continued to oversee the Ministry's operations and assets until formally ending in 1993. It was a ...

Miles Whitney Straight
The Miles M.11 Whitney Straight was a 1930s twin-seat cabin monoplane designed and produced by the British aircraft manufacturer Miles Aircraft. It was named after Whitney Straight, a Grand Prix motor racing driver, aviator and businessman. The aircraft was the first combine a side-by-side seating arrangement with an enclosed cockpit for the general aviation sector. The Whitney Straight was developed after F.G. Miles and Straight recognised that they had similar ambitions to develop modern aircraft suited to flying clubs and private owners alike, and thus decided to collaborate on its production. On 14 May 1936, the first prototype conducted its maiden flight at Woodley Aerodrome; quantity production commenced shortly thereafter. Whitney Straights were used in various roles within the civil market, such as air racing and aerial topdressing. Approaches were also made by Miles to introduce the Whitney Straight into the military market. While not selected as an army cooperation ai ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Fertilizer
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal from ...

Aerial Topdressing
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. Origins Previous aerial applications The first known aerial application of agricultural materials was by John Chaytor, who spread seed over a swamped valley floor in Wairoa, New Zealand, in 1906 using a hot air balloon with mobile tethers. The first known use of a heavier-than-air machine in aerial application was on 3 August 1921 when, as a result of advocacy by Dr Coad, a USAAC Curtiss JN4 Jenny piloted by John A. Macready was used to spread lead arsenate to kill catalpa sphinx caterpillars near Troy, Ohio, United States. The first commercial operations were attempted in the US in 1924 and use of insecticide and fungicide for crop dusting slowly spread in the Americas and, to a lesser extent, other nations. Crop dusting poisons enjoyed a boom in the US and Europe after World War II ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
