Location: Sustainable Agricultural Systems Laboratory
Project Number: 8042-22000-167-106-A
Project Type: Cooperative Agreement
Start Date: Jan 1, 2024
End Date: Nov 30, 2024
Objective:
The research will be carried out at two scales: in small-plots using a hand-held camera system, and on-farm using tractor-mounted cameras. This work will include drones in years two and three. The research network has developed two systems that are both inexpensive and efficient in collecting weed density and biomass. The first system uses a 3-D reconstruction technique (monocular camera and structure from motion analysis of digital videos) using a hand-held pole-mounted GoPro camera. The second system is a tractor-mounted sensor box consisting of multi-spectral, LiDAR, and ultrasonic sensors. Coupled with the data flow systems already developed by our network, both systems are expected to accelerate efficient data collection throughout the growing season and across locations. A mobile app has also been developed for collecting pertinent meta-data that accompanies the collected video data. These technologies have already been beta-tested at select locations in the US. This project will greatly expand the coverage across important US soybean production regions and calibration for more weed species. Further, a web-based user interface will be developed that automates data analysis, visualization, and recommendation systems.
Approach:
The Agency Location is engaged in research addressing cover crops and weed management. Under the authority of 7 USC 3319a, ARS desires to acquire goods and services from the Cooperator to further agricultural research supporting the independent interests of both parties.
