RSD – Row-specific nozzle positioning

Flexible boom and sensors allow the nozzle line to be moved above the row.

Row-specific nozzle positioning

As little as possible, as much as necessary: With the “row-specific nozzle positioning RSD”. For this purpose we offer our customers a further innovation for the environmentally friendly and economical consumption of crop protection agents, this time specifically in band spraying. With row-specific nozzle positioning, the nozzle is guided precisely over the row by active control using a camera. The pesticide is only applied to a part of the area, the amount of drift is automatically reduced – and legal requirements are complied with due to the precise distribution.

The system is suitable for cultivation in row crops, such as vegetable cultivation. The first adjustment is made manually before application: The nozzles are simply positioned above the rows. During application, a flexibly movable boom and sensors take over this task and ensure precise distribution of the crop protection agents. RDS can also be used with a GPS device via an ISOBUS operating terminal and software.

The system enables band treatment in row crops with large working widths and offers an ideal complement to mechanical weed control between rows.
The new process was presented for the first time at Agritechnica 2019 in Hanover. It is currently undergoing final testing.


  • How does Dammann basically implement the topic technically?
    Nozzles are actively controlled above the row. Sensors and movable booms ensure precise application.
  • Is a second line used, if so, where exactly is this mounted?
    A second line is not required for this.
  • Is the row spacing specified in a certain grid or are different row spacings possible (45, 50, 75 cm)?
    Different row spacings are possible and are manually aligned in advance.
  • How can the system be adjusted to different row spacings?
    The boom is manually adjusted to different row spacings before application.
  • How is it ensured that the band spray nozzles operate exactly above the row? Is there active steering?
    Yes, there is active steering. A technology developed by us can detect via sensors where and at what intervals liquid is to be applied.
  • Which nozzles do you use? How do the band spraying nozzles differ from the conventional nozzles?
    Special nozzles are used for band spraying. They differ in their spray cone, which, unlike other nozzles, reduces liquid through an acute angle and applies it precisely. This makes it possible to work in a particularly environmentally friendly and low-loss manner.
  • Do you need other fittings/pumps or is the use in the conventional liquid system possible?
    The use is possible in the conventional liquid system. The aim is also to retrofit on other equipment, for example on existing machines that are already in use.
  • How high do you estimate the saving of funds? Where do you see the main areas of application? Is there a demand for these solutions in practice?
    There will be a considerable savings potential. The envisaged trial runs will show how high the percentage effect will be.
    Main areas of application: Strip spraying in row crops.
    The process is already in demand: customers are being “put off” until the trial has been completely run.
