Aerial application

In some regions, large areas of farmed land are classified as hill country and traditional ground spreading vehicles are unsuitable when spreading soil conditioners like crushed limestone. Since the 1950's in New Zealand, farmers have been applying crushed limestone via fixed wing aircraft or via helicopter to nurture and cultivate difficult to reach terrain.

Trials conducted in New Zealand over a three year period showed that the main pasture response to the limestone occurred after the initial application and then increased over time. Other pasture and soil related responses recorded included improved legume content, decreased pasture litter and an increase in earth worm numbers. Find out more about these lime trials in our additional resources below.

In response to customer demand and after two years of product development, Graymont developed a specific product for the aerial topdressing market known as AeroLime®. AeroLime® has been configured to meet agronomic expectations and to meet the guidelines laid out by the New Zealand Civil Aviation Authority.

AeroLime® is currently only available in New Zealand.  Please refer to our related product page to view more information about AeroLime® or contact our sales team.

After processing, products derived from limestone can eventually revert to their original chemical form by reacting with carbon dioxide in the atmosphere or from industrial processes.
