Aerial Top Dressing c.f. Crop Dusting. As there has been some debate about this my understanding is Topdressing concerns the delivery of fertilisers, (usually superphosphate and lime), where as Crop dusting initially referred to the use of insecticides and fungicides; it seems disputed whether it now includes topdressing as a catergory.

All material to date suggests top dressing was invented in New Zealand some twenty years after crop dusting began, it is quite possible the parochial pride allowed previous researchers to overlook prior foreign invention, which for some reason did not widely catch on.

People with local histories, please add them, and we'll take the "New Zealand" out of the title. Winstonwolfe
