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.
