The IBLA (Institute for Biological Agriculture and Agro-Ecology) is pleased with the results of its work so far, with some techniques showing very positive outcomes.

To protect the quality of drinking water, local agricultural businesses are on a path to reduce their use of plant production agents and pesticides. In a trial field in Luxembourg, the town has been assessing various methods to avoid chemical products. The results from this pilot project were presented on Tuesday evening.

In a field in Lorentzweiler, diverse crops of corn and runner beans are being harvested. These mixed patches aim to optimise vegetable yields in both quality and quantity without relying on conventional fertilisers. Instead of using pesticides, weeds growing alongside the crops are now managed using a mechanical weed control method.

This method employs a so-called curry comb or corn-harvesting machine, which is much less harmful to our drinking water, explains Alexander Schlimm, the drinking water coordinator for Luxembourg City’s waterworks. The IBLA reports promising results from the experiments conducted in Lorentzweiler.

"Overall, we are very satisfied. We have received confirmation of our trials and expectations. I believe the corn we have harvested mechanically is just as good as conventionally grown corn," said a spokesperson.

Currently, seven protected drinking water zones have been established in Luxembourg. Agricultural businesses operating in these areas can contribute to the protection of drinking water by supporting local agricultural initiatives. Additionally, they can request to use the corn-harvesting machine for free through the committee for drinking water suppliers, further aiding in the protection of safe water consumption.
