Air monitoring helps anticipate possible ecosystem changes
Date:6/25/2008

position of inorganic nitrogen ammonia plus nitrate is between 3.5 or 4.5 pounds of nitrogen per acre per year.

"Compared to how much nitrogen we put on irrigated grain crops, it's not much, obviously," he said. "But on nutrient-poor rangeland, who knows?

"We don't know what an undisturbed background level would be in this region of the state," Auvermann said. "We can't really say without more information if a certain amount of deposition is good or bad. Right now we are getting the baseline and looking at how it relates to the surrounding sites that have been monitoring deposition for a lot longer than we have."

Auvermann is especially excited about using the Canonceta site as a living laboratory for science students from middle school to college.

"This kind of environmental monitoring is where it all comes together: meteorology, chemistry, physics, biology and ecology," he said. "It's all here."
