In a significant leap for precision agriculture, Dutch vegetable grower Adrie van den Einden has invested €1.4 million in a cutting-edge LaserWeeder developed by U.S.-based Carbon Robotics. Van den Einden, who manages 235 hectares of farmland in the Netherlands, including 27 hectares of organic crops, has been utilizing the LaserWeeder for nearly a season and expresses profound satisfaction with its performance. “We’ve gained confidence in it, and it’s a good investment. Better than this doesn’t exist anywhere in the world,” he states, emphasizing the machine’s unparalleled capabilities in weed management.
The LaserWeeder employs advanced technology, including computer vision and AI deep learning models, to identify and target weeds among crops. Equipped with 30 high-powered lasers and ten crop cameras, the machine operates with millimeter precision, capable of detecting weeds at their cotyledon stage—just after germination. The lasers are directed by movable mirrors, allowing the machine to scorch weeds instantly, producing visible curling plumes of smoke as they are eradicated. “The machine works with millimeter precision,” Van den Einden notes, highlighting its effectiveness.
One of the standout features of the LaserWeeder is its operational efficiency. It can eliminate up to 80 weeds per second, averaging between 3,000 and 4,000 weeds per minute. This remarkable speed is complemented by the machine’s ability to operate without disturbing the soil, a significant advantage over traditional weeding methods such as hoeing or pulling. By avoiding soil disturbance, the LaserWeeder minimizes the risk of stimulating dormant weed seeds to germinate, thereby enhancing long-term weed management.
Van den Einden’s approach with the LaserWeeder is tailored to his farming goals. The machine can be configured to either remove all weeds, even at the risk of damaging crop plants, or to avoid harming crops while leaving a few weeds behind. “Our goal is to hit every weed without harming any crop plants, and we’re almost there,” he explains, underscoring the machine’s adaptability to different farming strategies. After just two treatments spaced 14 days apart, the LaserWeeder can clear crop beds of more than 99% of weeds, allowing any remaining weeds to be outcompeted by the crops.
The investment, while substantial, is seen as a necessary step towards modernizing agricultural practices. Van den Einden acknowledges the machine’s cost, which includes an annual licensing and support fee of €60,000, escalating to €122,000 for year-round use. However, he believes the benefits far outweigh the expenses. “This machine is the future of precision farming, and for us, there’s nothing better on the market,” he asserts.
The decision to invest in the LaserWeeder was influenced by thorough research and firsthand experiences. Van den Einden’s visit to Carbon Robotics’ factory in Seattle and discussions with a fellow grower in Arizona, who had ordered a second machine, played crucial roles in solidifying his confidence in the technology.
As the agricultural sector increasingly seeks sustainable and efficient solutions to combat weed management, innovations like the LaserWeeder represent a transformative shift. By harnessing the power of AI and laser technology, farmers like Van den Einden are not only improving their operational efficiency but also paving the way for a more sustainable approach to farming. The implications of such advancements extend beyond individual farms, potentially reshaping agricultural practices on a global scale and addressing the pressing challenges of food production in an environmentally conscious manner.
