Researchers Track Agricultural Sulfur Runoff

Researchers from the University of Colorado Boulder are studying the environmental fate of sulfur that is applied as a fungicide by California winegrowers. Research published in Environmental Research Letters tracked the unique fingerprint of the agricultural sulfur as runoff through downstream waterways. Sulfur is the top pesticide used in California agriculture, mostly in vineyards. “This work could help inform the development of technologies that help farmers to choose when and how much they apply, rather than just applying the same amount preventatively all the time,” explained the study’s senior author Eve-Lyn Hinckley. “My objective as a scientist is to always work in partnership with the landowners and with the farmers. My hope is that we can reach a place where they’re able to continue in a very sustainable way that also protects the surrounding environment.”
