Flow Rate Additional calculation If measured
flow rate differs from pre-calculated flow rate
Adapt the pressure-setting. Always stay within
the nozzles optimal pressure range.

Adjustments to the Orchard

• Stationary air-flow-test
• Prepare two poles, at least 50 cm higher than the
  canopy.
• Fix flagging tape to poles at the four levels
  above canopy top end of canopy, lower-end of
  canopy and below canopy.
• Place poles in tree row adjust the air-flow
  with baffles.

Above canopy Should not move
Canopy-top Movement
Canopy-low Movement
Below canopy Should not move

Dynamic spray-pattern and distribution
monitoring

• Use of Water Sensitive Paper (WSP)
• Fix WSP to leaves (diverse positions)
• Spray while driving through arrangement
• Check droplet-patterns
• on WSP
