Introduction:
In a bid to enhance agricultural productivity while ensuring environmental sustainability, robotics and automation technologies are being adopted. Precision agriculture using robots can significantly reduce the risk of chemical runoff and promote eco-friendly farming practices. The Center for Precision & Automated Agricultural Systems (CPAAS) at Washington State University is developing a machine-vision solution to accurately apply nitrogen in apple orchards, optimizing fruit yield and quality while minimizing environmental impact. This system aims to address the challenge of determining the optimal application rate of nitrogen fertilizer and help farmers implement precise farming practices. The robot platform chosen for this project is the Warthog, which offers the necessary capabilities and payload capacity. Using various sensors and cameras, the system can accurately assess the nitrogen state of individual trees and apply the required amount of nitrogen at the right time and location, enabling efficient orchard operations. Beyond nitrogen management, the Warthog platform is also being utilized for other robotic projects in orchards, including harvesting, pruning, pollination, and thinning.

Robotics and Automation Revolutionize Precision Agriculture
A Solution to Reduce Nitrogen Pollution in Agriculture
Over-fertilization in agriculture poses significant risks to the environment, leading to pollution and negative economic impacts. Farmers often struggle to determine the optimal application rate of nitrogen fertilizer, resulting in excess amounts being used to ensure productivity. However, excessive nitrogen can harm plants and contribute to environmental problems. To address this challenge, the Center for Precision & Automated Agricultural Systems (CPAAS) at Washington State University is developing a machine-vision solution for precise nitrogen application in apple orchards, aiming to improve both productivity and sustainability.
Balancing Nutrient Needs and Environmental Impact
Traditional agricultural practices often lead to excess nitrogen entering groundwater and causing pollution, particularly when more than 50 kg of nitrogen per hectare is applied. The CPAAS is working to optimize nitrogen application by monitoring individual trees in apple orchards. By assessing the nitrogen levels of each tree and applying the precise amount at the right time and location, the system aims to enhance fruit yield and quality while minimizing environmental impact.
Integrating Robotics for Precision Nitrogen Application
Developing a machine-vision system to monitor tree growth and optimize nitrogen requirements is a complex task. The CPAAS chose the Warthog, a versatile autonomous platform, as the base for their system. The integration of multiple sensors, including NVIDIA Jetson devices and GPS positioning modules, allows for accurate tree mapping and precise nitrogen application. Cameras such as Stereolabs ZED2 and Intel Realsense provide crucial data on fruit tree canopies, enabling the efficient spraying of nitrogen in the root zone of each tree.
Efficiency and Convenience of the Warthog Platform
The decision to utilize the Warthog platform was driven by its superior payload capacity, robustness, and the extensive support and documentation available. The Warthog’s widespread use among collaborators also contributed to its selection. Without the Warthog, the team would have faced significant challenges building their own platform or developing autonomy for a conventional tractor. The Warthog’s off-the-shelf availability streamlined the project and reduced potential risks.
Expanding the Applications of Warthog in Orchard Operations
The CPAAS team’s work with the Warthog extends beyond nitrogen management. They are using the platform for various orchard-related projects, including harvesting, pruning, pollination, and flower and fruitlet thinning. The success of the system in monitoring tree growth and applying nitrogen accurately has encouraged the team to further develop its autonomy, creating more automated solutions for agricultural operations.
“We chose the Warthog robot due to its higher payload. It is a robust, well-supported and documented system. The robot has been around for a long time and some of our collaborators use it, so we knew what we were getting.” – Achyut Paudal, PhD Student, Center for Precision & Automated Agricultural Systems, Washington State University
The team’s ongoing efforts involve mapping information on each tree and integrating data from multiple field passes into a decision support system. This system will generate prescription maps for nitrogen application at the individual tree level, further optimizing orchard operations.
