2024 MN On-farm Precision Agriculture Research Network Meeting

On February 15, 2024, the UMN Precision Agriculture Center organized the 2024 On-farm Precision Agriculture Research Network Meeting to share and discuss the results of 2023 on-farm precision agriculture trials and plan for 2024 on-farm trials.  The participants included collaborative growers, crop consultants, university researchers, graduate students, an USDA ARS scientist, Minnesota Department of Agriculture scientists and industry collaborators. In addition to the in-person meeting, an on-line option was also provided to those who could not join in person. 

Precision Agriculture Center Seminar Series

Thanks to everyone that attended and participated in today's seminar! A special thanks to Brian Bohman for presenting his work on remote sensing for predicting the nitrogen nutrition index in potato.

We encourage everyone to draft a blog-style post about any aspect of your research so we can get more content up on the PAC website. Remember - include a summary, keep it short and simple, and include plenty of photos and figures. Send your draft to Yuxin or Tyler to get it published on the website.

Artificial intelligence and hyperspectral imaging for high-throughput plant phenotyping

Aerial hyperspectral imagery and deep neural network for yield phenotyping in wheat.

Artificial intelligence (AI) is becoming an increasingly imperative tool for sustainable crop production in the era of digital agriculture. In this talk, I present my Ph.D. research work in which I utilized AI to leverage the unique advantages of hyperspectral imaging for investigating desired phenotyping traits in wheat with both indoor and field setups.

For our indoor setup, we developed a sensor-based framework for analysis of hyperspectral images to assess the difference between the salt tolerance of four wheat lines. We were able to attain a quantitative ranking as early as one day after applying salt treatment. In addition, we developed an ensemble feature selection pipeline to identify the most informative spectral bands associated with the desired trait in plant phenotyping. I present the results of testing the developed feature selection pipeline in finding the most prominent bands for salt stress assessment and Fusarium head blight detection in wheat.

For our field setup, we mounted the hyperspectral camera on an unmanned aerial vehicle to collect aerial imagery in two consecutive growing seasons from three experimental yield fields composed of hundreds of experimental wheat lines. We trained a deep neural network with fully connected layers for yield prediction. While conventional harvesting of plots for yield measurement relies on demanding, extremely laborious, and time-consuming tasks, our automated framework could predict the yield of wheat plots in a fast, cost-effective manner. In addition, our framework offers a unique insight for breeders to investigate the yield variation at sub-plot scale - a valuable new index in breeding programs to nominate high-yielding cultivars that are capable of producing a uniform yield across the plot. The results revealed that the proposed framework can also serve as a valuable tool for remote visual inspection of the plots and optimizing the plot size to investigate more lines in a dedicated field each year.



Dr. Ali Moghimi | Biological and Agricultural Engineering | Digital Agriculture Lab | University of California - Davis

Presenter biography:

Ali is currently a postdoctoral research associate working in the Digital Agriculture lab at the University of California, Davis. He is passionate about conducting interdisciplinary research centered at the food-water-energy nexus. Ali's current research focuses on applying innovative technologies (LiDAR and multispectral/hyperspectral imaging), automation (UAVs), and artificial intelligence (machine learning and deep learning algorithms) in agriculture to facilitate the digital revolution in agriculture. He completed his Ph.D. at the University of Minnesota in February 2019. His Ph.D. research focused on developing sensor-based, automated frameworks for high-throughput phenotyping in wheat.

Ali is currently working on the following projects at the University of California, Davis:
Project 1: prediction of nitrogen status in table grape using aerial multispectral imagery
Project 2: developing a canopy profile mapping technique using UAV-based LiDAR data for almond orchards
Project 3: developing a low-maintenance system to reduce spray drift without limiting the spray and air delivery

Seminar hosted by the Precision Agriculture Center

8 March 2019 - Precision Agriculture Center hosts leading researchers as part of the Production Agriculture Symposium

Several students affiliated with the Precision Agriculture Center served on the organizing committee for the 2019 Production Agriculture Symposium. This year's topic was Dialing in: Precision Agriculture in Action, and included three keynote addresses, student oral presentations, expert panel discussions, and a student poster session/competition throughout the day. Overall, it was a great turnout with around 240 attendees - thank-you to all who participated!

A special thanks to Corteva Agrisciences, the Minnesota Soybean Growers, and the Minnesota Corn Growers for sponsoring the event!
