In the ever-evolving landscape of precision agriculture, spot spraying has emerged as a hot topic, promising to revolutionize how farmers apply chemicals. Traditionally, spot sprayers are envisioned as small, precise machines that apply chemicals in narrow sections. However, a French innovator, Carbon Bee, has disrupted this notion with a retrofit kit that can transform existing boom sprayers into highly precise application machines.
Carbon Bee’s SmartStriker X is a camera retrofit kit designed to be plug-and-play, compatible with both new and existing boom sprayers. Unlike traditional spot sprayers, the SmartStriker X operates with theoretical sections of at least 25 centimeters in width, making it suitable for wide machines. The system has been available for some time, previously through spray technology manufacturer BBLeap, and is now distributed by mechanisation company Hogervorst in Noordwijkerhout, South Holland.
The SmartStriker X’s camera housing contains a built-in 3D and RGB camera, collectively known as the Sensor X. This compact and lightweight system has a field of view of 3 meters in width and 3 meters ahead. For spot spraying, the 3D camera continuously generates a 3D map, which is sent to a central computer. The software then analyzes this 3D model to determine whether the detected plant is a weed that needs to be sprayed. This process is a blend of complex AI algorithms and human input, ensuring accurate decision-making.
The nozzles open or remain closed based on the software’s analysis, with communication handled directly via internet cables rather than the Isobus. This direct linkage allows the system to accurately spray at speeds of up to 25 km/h, a speed more common in countries like Australia than in the Netherlands.
The SmartStriker X’s data is transmitted directly to the controller via a data cable, ensuring that the system has enough time to identify plants, make a decision, and open the correct nozzles. The system’s compatibility with most Isobus consoles and its regular software updates make it a versatile tool for modern farming.
Beyond spot spraying, the Carbon Bee system can also perform dual-dose spraying and modulation. When paired with a suitable Pulse-Width Modulation (PWM) pulsing nozzle system, the system can apply a low herbicide dose across the entire field for small emerging weeds while giving larger plants a full dose. This reduces chemical usage without underdosing stronger weeds, which could lead to resistance and continued growth. Additionally, the system supports modulation, adjusting chemical dosage based on plant biomass density.
The Carbon Bee camera system costs €2,800 per meter, including installation and support. While this may seem like a significant investment, Hogervorst claims that an arable farm of approximately 200 hectares can recoup the cost within one to two years through reduced chemical usage and increased crop yields. However, it’s important to note that this system requires careful preparation and operation. The cameras are not designed to handle swaying, unstable booms, and operators must still estimate the required chemical volume in advance.
As more crop protection products become restricted, systems like the Carbon Bee SmartStriker X offer a promising solution. However, it’s crucial to approach this technology with a realistic mindset. It’s not a plug-and-play solution that works effortlessly. Instead, it’s a powerful tool that, when used correctly, can significantly improve the efficiency and sustainability of farming practices. As the agricultural industry continues to evolve, so too will the technologies that support it, and spot spraying is just one piece of this complex puzzle.
