Higher Fertilizer Use Reduces Pollinators by Half and Plants Suffer in Response, Study Finds [Video]

While scientists have long known that pesticide use could impact pollinators, a new study reveals how fertilizer could negatively impact these important organisms. Not only that, but the research, which was conducted at the site of the longest ecological experiment in global history, revealed that high fertilizer use could also lead to a decline in flowering plants.

A team led by researchers at the University of Sussex and Rothamsted Research examined fertilizer use over a two-year period at the Park Grass Experiment, Rothamsted. The site is home to the longest-running ecological experiment in the world, which was originally established in 1856 to determine how inorganic fertilizers versus organic manure impacted hay yields, but researchers in the 1850s found that these fertilizers and manures were negatively affecting local species. Following that discovery, the site has become an ongoing experiment to test impacts of varying factors on ecology and soil health.
