Nah, it's still the cows. No citation of a livestock emissions figure is made by the author. They took an excellent study which didn't mention cows at all and repackaged it as clickbait for this company's blog...
29 gigagrams of methane per year from fertilizer plants, says the study. (The 28 gigagrams figure in the article is misquoted, Ctrl+F for "29 (±18) Gigagram per year" here https://www.elementascience.org/article/10.1525/elementa.358/ https://www.elementascience.org/article/10.1525/elementa.358... )
6.2 teragrams of methane per year from livestock emissions, says this other study https://extension.psu.edu/livestock-methane-emissions-in-the-united-states https://extension.psu.edu/livestock-methane-emissions-in-the...
Last I checked 6.2 teragrams is a lot more than 29 gigagrams.
On another note... I highly recommend looking at the original paper. Awesome visual of emissions data captured by Cornell University sensors onboard a Google Street View vehicle!

It's unfortunate that so much methane is released by fertilizer plants through incomplete chemical reactions, improper combustion, and leaks. 100x more than was previously estimated, in fact.
Also a bit curious - how did Cornell researchers get their sensors onboard a Google Street View car? Did Cornell approach Google for this study or vice versa?

It’s not unfortunate. It’s not luck. It’s design. And since it’s technology, not fortune, it can be redesigned and reworked.
