Arsenic in Turfgrass Systems

Arsenic is commonly added to turfgrass via pesticide and fertilizer applications. We are currently in our second year of field trials investigating arsenic mobility in turfgrass systems.

Here Audrey preps some porewater samplers and Ethan gets them installed.

The field site is set up to examine arsenic dynamics with and without turfgrass.

Matt J. gets the experiments initiated.

At select times, we'll sample porewater, and then begin analyses in our makeshift lab in the research station shed.

We also collect soil samples to measure arsenic profiles.

Then it's back to NC State for analysis!
