Balance
Grain likely outside for a short time
Usage = 200 – 240 MM Bu/month

11. Corn Quality –Scenarios for 2015
Warm and Wet
Large kernels, medium/low test weight, wet corn
Fair to poor storage properties
Maybe vomitoxin?
Cool and Wet
Large kernels, medium/low test weight, 20%+MC
Poor storage properties
Vomitoxin more likely
Warm and Dry?!:
Large kernels, medium/low test weight

12. Corn Quality Trends - Example
Plots are usually ~ 2 lbs/bu heavier than field run, ~ 2 % pts drier
4 strip trial tests, hybrids/location; Adair, Black Hawk, Bremer, Palo Alto counties in Iowa

13. Soybean Quality –Scenarios for 2015
Warm and Wet
Large beans, slow drying plants, good protein
Probably wetter beans/mixed beans at first.
Cool and Wet:
Large beans, wetter beans, composition?
Beans rewet to 14-15%, slow to dry after that.
Warm and Dry:
Large beans, high protein, normal moisture
Some later harvest fields.
More harvest beans this year?

14. Soybean Quality Trends - Example
4 strip trial tests, varieties/location
Adair, Black Hawk, Bremer, Palo Alto counties in Iowa

15. Harvest 2015 – preparations
Clean bins, aeration, dryers.
Scout/evaluate before harvest.
Mold (especially if storm damage)
Lodging (Lots of disease pressure)
Variability; breakage and FM if low TW.
Corn – soybean balance may be hard to estimate.
More soybeans will complicate end of harvest rush .

16. Harvest Basics Uniform drying and cooling (as best possible)
Adequate aeration (0.1 + cfm/bu)
Cooling cycle every degree change
Get below 40F as fast as possible
Take out the center core of fines immediately
Regular inspection, temperature monitoring
Temperature change is important (3 degrees)
Stay within temperature-moisture guidelines

18. Corn Harvest 2015 - complexities
2014 carryover corn in fair condition
Do not mix 2015 and 2014 in the same bin
Neither mixing nor layering will work
Rotate with 2015 crop or keep separate
First 2 weeks +/- : Submit daily composite samples. Can be out of dryer.
Check grading accuracy
Mycotoxin issue?
Check Test Weight increase

19. Web-Based Training on Grain Storage

20. And Now There is FSMA! Animal Food to publish 9/17/2015
Feed mills, ethanol plants, etc. must have:
CGMP
Hazard Analysis/Qualified Person
Verified Preventive Control Plan
Handling and Storage: Exempt - above only
Supplier verification required – you are a risk for users.
Lots of materials will be available.

27. Consider having someone take this training when it is offered (next 1-2 yrs.)
ISU and others will have certified instructors.

28. Summary
Wet grain; lower and more variable test weight possible. Other risks depend on weather from here on. Watch out for harvest on warm days.
Carryover 2014 will create complexities. Do not mix years. Separate by high-low test weight if you can. Composite samples!
Some grain will be outside. Mix of corn and soybeans at harvest may shift somewhat.
Basic grain science principles still apply.
