Fertiliser spread pattern

Fertiliser spread pattern

When fertiliser is dropped from an aircraft, it moves sideways in both directions as a result of the air turbulence. The application rate is much greater in the centre of the flight path than the sides, so the pilot overlaps successive flights to even out the overall application. The amount of fertiliser on any part of the farm should be the same as the peak amount in the centre of each run.
