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, 20-40 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, 20-40 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. page 15

16. Harvest Basics –Uniform drying and cooling (as best possible) –Adequate aeration (0.1 + cfm/bu) –Cooling cycle every 10-15 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 page 16

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 page 18

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. page 20

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.
