At a nitrogen management class in the small town of Creighton, Nebraska, Tanner Jenkins shows a chart of groundwater data to a group of about 40 farmers. He points to a red line, which shows the level of chemical nitrates in groundwater over time.
“You can see we’re on a pretty steady upward click,” Jenkins, who works for a local groundwater district, tells the farmers.
Decades of intensive farming have contaminated the groundwater across many parts of Nebraska. A new plan may help farmers in the northeastern part of the state address the problem.
