Today, the department teaches crop sciences and breeding, soil sciences, meteorology, agroecology, and biotechnology.

Abstract
August is the time for estimating corn yields. By the end of September some of those estimates are being validated by yield monitors in combines harvesting this year's bounty. What will you do with your yield maps? Yield monitors have been in use since the early 1990s. In today's era of "big data" technology, yield maps are providing information to feed into the big data black box.
