The College of Michigan used a $3 million Pure Science Basis grant to develop a urine-based fertilizer that has since been utilized to peony vegetation on the faculty’s Nichols Arboretum, with researchers reporting that the fertilizer decreased greenhouse gasoline emissions, in keeping with ABC 13.

“We now have used the time period, ‘pee on the peonies,'” UMich Environmental Engineer Nancy Love mentioned. “After which it grabs individuals’s consideration, after which we will speak to them about nutrient flows and nutrient effectivity in our communities and methods to be extra sustainable.”


Some individuals assumed it was OK to “drop their drawers” and urinate on the flowers. Consequently, the college will use the time period “pee for the peonies” as a substitute.

The Nichols Arboretum’s peony backyard has over 800 peonies and as much as 10,000 flowers at peak bloom.
