A topic that has been on many crop farmers minds is the derecho that took place in much of Iowa on 10 August. Steve Johnson, Iowa State University Farm Management Field Specialist, recently reviewed what is known and unknown about the damage done by the derecho. Initial reports indicated 10 million acres damaged in 57 Iowa counties. USDA’s Risk Management Agency estimated 8.2 million acres of corn and 5.6 million acres of soybeans were damaged. Later satellite imagery used by the Iowa Department of Agriculture estimated that 36 counties had serious damage on 3.57 million acres of corn and 2.5 million acres of soybeans. Initial estimates indicate a possible 150 million bushel corn production decline. Heat and drought in part of the area have added to the probable crop reduction.
Farmers now have more price uncertainty than we thought likely 3 weeks ago. Some of the damaged acres will produce some crop but no one knows how much. Some of the pictures of the Iowa derecho damage lead one to suspect some cornfields will only be able to be harvested in one direction. Some die back is evident from the satellite images released. Moreover, there is a question about whether soybeans will be more or less resilient to the derecho damage that occurred. Another issue though is the loss of millions of bushels of crop storage. Iowa coops estimate replacement will cost $300 million.
One piece of information we do have is corn crop ratings. These are lower in Iowa, Chart 1, than any year since 2012. But that isn’t the full story as Chart 2 shows. US corn crop ratings are still above 2017 and 2019. It may be possible that much of the Iowa damage will be offset by very good yields in Il, NE and MN.

Additional information will come to the market slowly. Producers should watch for solid information to plan post-harvest sales, which could put Nebraska farmers in a better financial place than we thought at the beginning of August.
