CropProphet provides weather-based corn yield (and soybean) and production forecasts.  Our crop yield and production forecast model is based on county-level data and analysis but we focus on providing the most accurate possible national-level forecast of corn and soybean production.

In other words, we help grain traders, grain merchandisers, and discretionary and systematic commodity traders manage weather risk by quantifying the impact of weather on grain crops.  A wide range of grain commodity traders seize grain market trading opportunities using CropProphet by knowing the differences between market perceptions of corn production and our accurate forecast.  As the market perception corrects towards the CropProphet forecasts corn prices change. Our customers have an information advantage in the grain market.

Knowing the impact of weather on national grain yield is hard.  We make it easy.

The information below provides the top corn-producing counties for each year from 2000-2022.  You can also view corn production rankings by state or ask “What state produces the most corn?

What county produces the most corn?

As shown in the table below, the US county that produced the most corn in 2022 was McLean County, Il. It has been the top corn producing US county since 2013.  The drought of 2012 knocked McLean county off it’s perch, when it was the second most corn producing state in the United States.
