University of Illinois emeritus professor Emerson Nafziger tells the Crop Management Conference that Illinois corn and soybean yields have trended upward for more than 60 years. Over the past 40 years, corn yields have risen about 2.2 bushels per acre per year.
He argues that climate change is unlikely to halt that trend.
This is a long-range yield outlook with no near-term supply effect. It counters pessimistic climate-driven yield forecasts that could otherwise weigh on long-term price expectations.
