Laser versus weeds: LZH shows Farming 4.0 at the Agritechnica

08.11.2019

Lasers instead of pesticides - the Laser Zentrum Hannover e.V. (LZH) will be showing this Farming 4.0 vision for the first time during the AGRITECHNICA in Hannover from November 10th to 16th, 2019, at the Pavilion of the state of Niedersachsen (hall 21, stand A05).

The new approach of the LZH is based on the non-contact, optical interaction of light with biological material: cameras can be used to distinguish weeds from crops.


Vision of an agriculture of the future, by means of autonomously driving or flying systems, weeds can be removed from the field in a sustainable and environmentally friendly way.

With a laser beam, the growth center of weeds can be damaged, thus giving the crop plants growing right next to it the decisive growth advantage - without any herbicides and resistance formation.

This is the basis for using laser radiation to precisely damage weeds and thus help crops to gain a decisive growth advantage.

The use of herbicides can be drastically reduced with such a process. Since laser radiation acts purely physically, no resistances are formed, the soil can be preserved and beneficials are protected.

In addition, the laser-based approach can easily be integrated in Digital Farming.

Removing weeds from carrots, sugar beets and onions

The first application areas are crops with a high added value in organic farming, such as carrots, sugar beet and onions.

The operation of such a laser-based system is possible on different platforms: autonomous, self-driving, front-mounted or rear-mounted.
