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 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.
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.
