This past week was tough at times yet also incredible to see people pull together, rally around each other, and donate so much. All of this is so hard to put into words…praying for those impacted and grateful for the many heart-warming stories amidst all the loss! I realize not everyone reading this is directly affected by the flooding. However, we all most likely know others affected and there’s several resources and information Nebraska Extension wishes to share. Please help us in sharing this information!

Flood Website: http://flood.unl.edu Information for Rural/Urban, Families, Business, Crop and Livestock Producers, Home Damage, and English/Spanish resources all in this one spot. Grateful for all my colleagues working really hard to redo/update this site! Also, all flood-related questions can be directed to: floodresponse@unl.edu

Volunteers: https://flood.unl.edu/how-can-i-help Individuals and organizations should never self-deploy. Support relief organizations that are already established in the area by contacting local organizations to see what support they need. You can also check with your county Emergency Manager. It’s also recommended to get a tetanus shot if you’re cleaning up in flood affected areas.

Homeowners: https://flood.unl.edu/cleaning-after-flood

Livestock: https://flood.unl.edu/livestock Our livestock producers care so greatly for their animals and work so hard to keep them safe and healthy. Prayers for all affected.

  • Options for Disposal of Animal Carcasses including rendering and landfill locations, burial and composting considerations. EQIP assistance for disposal costs may be available; apply for waiver through local NRCS office before disposal: https://beef.unl.edu/beefwatch/options-disposal-animal-carcasses
  • Contact local Farm Service Agency regarding losses. Phone call starts the process and only have 30 days to report for Livestock Indemnity Program. Can report losses from severe winter prior to flooding in addition to flood and blizzard events: https://beef.unl.edu/beefwatch/extreme-weather-events-and-livestock-indemnity-program
  • Article I’ve promised for a few weeks regarding the extreme winter before the flood/blizzard event: https://beef.unl.edu/beefwatch/considerations-attributing-livestock-losses
  • Flood damaged grain and hay is considered adulterated and cannot be used as a food or feed source; it must be properly disposed: http://deq.ne.gov/publica.nsf/pages/11-023
  • Post bomb-cyclone recovery
  • Wet hay has the potential to combust so remove hay from building structures if impacted by flooding. Best practice for flooded hay and silage is to dispose of by spreading on fields as a fertilizer. Most practical way may be just unrolling bales for now. Hay bales that are at 30 to 40 percent moisture content pose the greatest risk of fire. Check hay storage often for pungent odors, hot damp areas on the stack, emission of water vapors and other signs of heating. To check a stack’s temperature for fire risk, drive a sharp pointed pipe into the hay, lower a thermometer inside the pipe and leave it there for about 20 minutes. At 150 degrees F, the hay is approaching the danger zone. At 170 degrees F, hot spots or fire pockets are possible. Have the fire department on standby.

Flooded Grain Bins: Flooded grain is considered adulterated and needs to be disposed. Grain above that can be salvaged by removing it from the top or side of bin with a tool like a grain vacuum.

I don’t have room to mention all the resources! Please check out: https://flood.unl.edu/

Please keep talking to each other, share your stories, and don’t isolate! Eat a good meal, drink plenty of water, get some rest and be mindful of your personal well-being. Recovery is a marathon, not a sprint. We’re all being impacted by this. #NebraskaStrong is so true. It also takes strength to ask for help when we need it; help is always available!

Well, it’s been an interesting fall and I wish I had something more encouraging for our farmers this week…there have been some beautiful days/sunsets when the sun shone! Difficult with soybeans germinating in pods, popping pods, and the snow with so much harvest to go…hang in there and be safe when harvest resumes!

Regarding grain drying questions, Dr. Ken Hellevang at North Dakota State University has written several CropWatch articles at http://cropwatch.unl.edu to help us. Here’s a few excerpts.

For those with questions about drying soybeans when harvesting at high moisture to get them out of the field: “Soybeans at 11% moisture have storage characteristics similar to wheat or corn at about 13.5% moisture, so 16% moisture soybeans might be expected to store similarly to about 19% moisture corn. It is important to be able to aerate the soybeans to keep them cool.

The amount of natural air drying that will occur in late October and early November is limited. The equilibrium moisture content of soybeans for air at 40°F and 70% relative humidity is about 12%. With this air condition drying should occur with soybeans above 12% moisture. However, the drying rate will be slow at typical in-bin drying airflow rates. An airflow rate of 1 cubic foot per minute per bushel (cfm/bu) is expected to dry 18% moisture soybeans in about 60 days. With an airflow rate of 1.5 cfm/bu the drying time is reduced to about 40 days. The drying time for 16% moisture soybean is slightly less. The drying time of 16% moisture soybeans is about 50 days. Adding supplemental heat to raise the air temperature by 3 to 5 degrees will permit drying the soybeans to about 11% moisture in about 40 to 45 days. Increasing the airflow rate proportionally reduces the drying time.

The moisture-holding capacity of air is reduced at lower air temperatures. As average air temperatures approach 35°F, natural air drying becomes inefficient and is not economical. Adding heat would cause the beans on the bottom of the bin to be dried to a lower moisture content and it would increase drying speed only slightly. Cool the soybeans to between 20°F and 30°F for winter storage and complete drying in the spring. Start drying in the spring when outdoor temperatures are averaging about 40°F.”-Ken Hellevang NDSU. See more about drying soybeans with heat including considerations for fire risk at http://cropwatch.unl.edu.

Cooling Grain: “Cool grain with aeration to extend the allowable storage time and reduce the potential for insect infestation. Temperatures below about 60°F reduce insect reproduction. Insects are dormant below about 50°F, and extended exposure to temperatures below about 30°F can kill insects. Cooling grain as outdoor temperatures cool will reduce moisture migration and the condensation potential near the top of the grain pile. Also, the grain should be cooled because moisture content and temperature affect the rate of mold growth and grain deterioration. The allowable storage time approximately doubles with each 10-degree reduction in grain temperature.

Grain should be cooled whenever the average outdoor temperature is 10 to 15 degrees cooler than the grain. Cool it to near or below 30°F for winter storage in northern states and near or below 40°F in southern states. Aeration ducts need to have perforations sized and spaced correctly for air to enter and exit the ducts uniformly and to obtain the desired airflow through the grain. The maximum spacing for aeration ducts is equal to the grain depth to achieve acceptable airflow uniformity.”-Ken Hellevang NDSU. You can view Ken’s website at: https://www.ag.ndsu.edu/graindrying.

Weed Science School Oct. 31 near Mead will address current weed science issues and recommendations for improving herbicide applications. The school will be held at the Eastern Nebraska Research and Extension Center near Mead, starting at 8:45 a.m. and ending at 4 p.m. Topics include: overview of weed control in Nebraska, NDA procedure to investigate off-target dicamba injury, industry perspective on herbicide discovery, 15 years of researching waterhemp, forensic analysis for dicamba injury, ultra micro rates of dicamba on soybean, weed ID, cover crops and weed suppression, and what does/doesn’t work in managing herbicide drift. The school is free and CCA credits will be available. Please register here: https://agronomy.unl.edu/weedscienceschool.
