Controlling weeds within the crop row in vegetable production remains challenging and often requires a high level of manual labour. In the I-ROWeed project, we investigated two novel techniques to address this issue: GPS-guided intra-row hoeing and abrasive weeding using fine particles. With GPS-guided intra-row hoeing, the machine knows the exact position of each plant and can hoe within the row using moving blades, retracting them precisely at the plant positions. This technique operates reliably but still leaves weeds close to the plant base. Abrasive weeding targets weeds with fine particles propelled at high air pressure and can completely destroy them. However, this method is only effective within a very narrow time window, when weeds are young and the crop is sufficiently robust. Applying abrasive weeding too early can even cause crop damage. Therefore, neither technique proves to be a standalone solution. The best results are achieved by intelligently combining different techniques. The project demonstrates that precision technology is valuable, but human expertise and timing remain decisive.
