Targeted irrigation with savings potential
Working with the North Rhine-Westphalia Chamber of Agriculture, a new irrigation boom was developed as part of the Water Framework Directive. The Exaktgießwagen for outdoor pot plant production is now ready for practical use. It delivers water precisely to the centre of each pot, saving water and reducing nutrient input into groundwater. This technology can save up to 50% of irrigation water for smaller pots and up to 75% for larger pots. The Exaktgießwagen is a registered utility model of Rathmakers Gartenbautechnik GmbH.
A short TASPO article about the Exaktgießwagen is available at this link.

Standard widths: 13.20 m / 21.20 m / 25.20 m / 29.20 m / 33.20 m; all widths up to 51.0 m are available on request. We also offer solutions for non-rectangular growing areas. Where the short sides have different lengths, special long-range nozzles ensure adequate irrigation of the outer areas along the long sides (maximum reach: 5 m).
Improvements in the second version
- The larger, more stable triangular lattice structure has through-openings that also make it suitable for roller tracks or conveyor belts.
- Liquids are no longer carried through the structure itself but through PE pipes, minimising frost damage and corrosion.

Both types of irrigation boom can run with their support wheels on woven ground cover, soil or concrete.
