Figure 2 (Boom Height) : This figure shows
a series of water-sensitive papers set up at 1.5 metre intervals from 1.5 metres
downwind from the point of spray release to 7.5 m, inclusive. The papers demonstrate
differences in spray coverage comparing a nozzle spraying from 50 cm from the
ground, to one spraying 100 cm from the ground. The resultant coverage is graphed
to show spray drifts further when booms are held higher off the ground.
