Study: Climate Effects On Ag Yields Vary By Location, Crop

LINCOLN – The global emergence of climate change should get farmers thinking and acting locally, according to nearly a half-century of data analyzed at the University of Nebraska-Lincoln.

The new Nebraska study suggests that climate shifts between 1968 and 2013 drove about 25 percent of the collective fluctuations in corn, soybean and sorghum yields across the Great Plains.

“Both temperature and precipitation had their fingerprints on that quarter of the variability, which (itself) varied with location and crop,” said study co-author Meetpal Kukal, doctoral student in biological systems engine...
