Potato Farmers Grapple With Climate Change’s Impact On Nitrogen Management

PotatoesFrom Wisconsin Public Radio, March 2, 2020.

The light, sandy soil of Wisconsin’s Central Sands region is well-suited for growing potatoes — a root crop that needs an ample supply of water, but is prone to rot and disease. Yet that sandy soil and potato’s high nutrient demand also exposes the region’s groundwater to nitrate contamination. Effects of climate change like increased extreme rainfalls and a longer growing season are expected to make nitrate pollution more difficult to manage. In this series, WPR is exploring how the state can adapt to and mitigate the affect climate change is having on some of Wisconsin’s most iconic foods.
