For flat to rolling farmland we typically use ground spread trucks with on board cranes, specialised enclosed mixing tanks to mix fertiliser into a thick slurry and encapsulated spinners to apply the fertiliser with a very even spread pattern.
For larger scale blocks where a suitable local airstrip is available we use planes to apply fertiliser. Fertiliser is mixed on site, pumped into the plane and spread through boom spray nozzles.
For patchwork paddocks, such as crops or where the farm does not have local access to a suitable airstrip we use helicopters to ensure fertiliser is accurately applied where it is meant to go. Fertiliser is mixed on site and applied through a specialised helicopter bucket.
