In 1948, New Zealand pilots began experimenting with aerial topdressing, using ex-WW2 aircraft to spread fertilizer and lime onto farmland. This practice revolutionized agriculture, allowing for the rapid development of pasture and increasing agricultural productivity. It was a major innovation for a country heavily reliant on farming and became a model for aerial agriculture worldwide.

While a practical agricultural development, this event represents the peaceful and transformative use of flight technology. It shows the transition of military aviation to peacetime pursuits and inspired many writers to explore the relationship between technology, the land, and national identity. It was often featured in regional poetry and literature that celebrated the pragmatic use of technology for the nation's economic prosperity.
