Efficient irrigation is one of the most important factors in crop production.A uniform water application within the wetted pattern, combined with proper overlap of the individual sprinkler patterns, distributes the water evenly across the crop area, giving the water the best opportunity to infiltrate intothe root zone. In addition, a uniform water distribution over the entire wetted diameter of the sprinkler keeps the instantaneous application rate low, which reduces the chance of ponding and runoff.
For the best irrigation performance two factors are crucial, reducing the kinetic energy of the water impact onto the soil and controlling wind drift. Delivering a consistent droplet size greatly reduces the loss from wind drift of the fine droplets/mist. In addition, a controlled consistent droplet size and uniform distribution of the droplets within the sprinkler pattern reduces the impact force typical of larger droplets on the soil. These kinds of droplets can cause soil sealing which in turn reduce the soil's water intake rate, increasing the possibility of runoff and thus keeping the water from reaching the target root zone.
