Selecting the spraying nozzles for liquid fertilising

To apply the liquid fertiliser more on the roots of the plant than on the leaves, three-hole nozzles are advantageous.

With three-hole nozzles, the outlets are oriented downwards. The liquid fertiliser is distributed through 3 openings with coarse droplets and virtually without pressure. This prevents spray mist and formation of small drops.

NOTE
The coarse drops hit the plants with low energy and roll off the plant surface. Although this avoids fertiliser burn to the greatest extent possible, drag hoses should be used instead of three-hole nozzles for late top dressing.

With seven-hole nozzles and FD nozzles, the outlets are not oriented downwards, but rather they point to the side. This allows very large drops to be produced on the plants using only slight impact forces.
