Crop Management Information
for Flood-Damaged Field Crops

xcessive rainfall occasionally causes widespread severe flooding or ponding of major agronomic crops in the U.S. Midwest, most recently in 1993 and 2008. However, more limited flooding or ponding damage occurs somewhere almost every year. Because of the infrequent occurrence of such crop damage from flooding, ponding, or saturated soils; growers and their consultants often have little experience in assessing crop recovery or identifying economically viable crop management decisions in the aftermath of the damage.

This Web site offers a compilation of flood-related crop management information written by crop experts from throughout the Corn Belt. The articles are organized by subject area. You can either scroll down the page to locate an area of interest or click on the list below.

When in doubt about the applicability of the information to your geographic area of the country, please contact the author(s) of the articles or consult with your own university Extension specialists.
