Flood Resources for Crops and Cropland


CropWatch is a central resource for Nebraska Extension information on crop production and pest management, including flood and storm damage information when the need arises. Articles are written by Extension educators and specialists throughout the state. Some of the stories are linked below. For additional resources, please search CropWatch or see CropWatch.unl.edu/tags/flooding (most recent articles). Also check Crop Reports for recent field reports and photos.

Information and Resources for Flooded Fields

When heavy rains lead to flooding and standing water in fields, these resources can aid in assessment of crop damage and help inform important decision-making for the remainder of the season.

Flooding and Ponding in Corn

Ponding or flooding of fields affects corn differently at different stages, depending on the duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.

Flooding and Ponding in Soybeans

Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.

Returning to the Farm after a Flood

Disaster recovery can be as dangerous as the disaster itself, especially on farms and ranches where machinery and equipment, livestock, and agricultural chemicals are displaced and co-mingled. Check out these recommendations from eXtension.org to stay safe.

Salvaging Flood-Damaged Agricultural Buildings and Farmstead Considerations

This resource describes how to assess flood damage to the interior and exterior of farm buildings, including what to look for now and what could weaken the structure or cause health concerns later. Pesticides pose a special concern during floods. Learn how to protect your farm and what to do in case of problems:

Flooding and Stored Grain

Flooding affects both the stored grain and the structures. If your stored grain becomes flooded, consider the flooded grain contaminated and remove the good grain from above. This Iowa State Univeristy Extension resource offers recommendations for salvaging as much quality grain as possible. More

Farming after the Flood Webinar: Farmer Perspectives, Agency Resources

Learn about flood recovery resources and programs available through NRCS, FSA, RMA, and the Army Corps of Engineers in a multi-state webinar recorded December 14 and now available online.

Representatives of state and federal offices joined with university extension to offer a 2 1/2-hour webinar for farmers and landowners affected by the 2011 Missouri River flood.  In addition to the government representatives, two farmers (one from Nebraska and one from Iowa) shared their experiences in repairing the physical and biological properties of their fields.  

View the topics and presenters and listen to individual webinar segments. Audio available

Following are resources which may be helpful to reference as you review information from the program.

The webinar will be posted to the Web for later viewing and will be linked from this page.
