Objective:
To determine the effects of climate change on corn production in the Midwest.

Approach:
NAEW will reinstrument one set of lysimeters, and collect runoff and water quality data from several watersheds under a corn-soybean-cover crop-buffer system. The data will be part of a large midwestern monitoring system that will evaluate novel production systems and climate change impacts. The NAEW provide runoff, erosion, water quality, ground-water recharge, and evapotranspiration data unavailable anywhere else among midwest project locations.
