Fake AI video invents University of Minnesota cover crop…

On May 6, 2024, a YouTube channel named Soil & Centuries published a 49-minute video titled "Scientists Tested 41 Cover Crop Mixes for 6 Years," which falsely claimed that a University of Minnesota research team conducted an extensive six-season trial. The video alleged that one specific three-species cover crop mix outperformed all others by 210%, citing detailed data points on nitrogen transfer and mycorrhizal network density. The University of Minnesota Extension confirmed that the study is completely fabricated and the content is AI-generated "slop" designed to drive clicks and advertising revenue.

What happened

The video utilized several techniques characteristic of AI-generated misinformation. It featured a narrator with an unnaturally perfect, stumbling-free delivery, stock imagery, and citations that led to non-existent data. The video explicitly named a University of Minnesota faculty member to lend the false claims credibility. Liz Stahl, a University of Minnesota Extension educator, first discovered the video after receiving an inquiry from a soil and water conservation district employee. After verifying with the cited faculty member that the research did not exist, Stahl and her colleagues reported the video to YouTube. Despite these reports and public comments identifying the content as fake, the video remained online as of mid-July, with its viewership climbing from 11,000 to over 36,000. The channel, Soil & Centuries, hosts dozens of other videos featuring AI-generated cover images. Extension educators warn that such pseudoscience exploits the trust placed in land-grant university research and advise the public to verify agricultural information directly through official university channels, such as verified blogs, webinars, and field programs.
