2 Grain Storage & Management Practices It is estimated by 2008, Iowa will need 115% of it’s present corn production to meet the continued increase in Ethanol Plant production. The ethanol industry has on average 7 to 14 days of corn storage capacity.
3 Grain Storage & Management Practices Does Iowa have adequate grain storage on the farm and at the elevator to meet the requirements of the ethanol industry? Does grain storage management on the farm meet the need for ethanol production? Does grain storage management in the elevator meet the needs for ethanol production?
4 Grain Storage & Management Practices What evaluation tools are needed to answer the questions for grain storage and management practices? Does existing storage meet the needs of the delivery cycle required by the ethanol plant? A flow model will help answer questions of storage needs.

7 Production and Corn Usage Summary Statistics n Ethanol Produced mil gal/yr Corn Used mil bu/yr DGS 000 tons/yr Current Dry-grind Plants * Plants, expansions under construction Wet Mills Nearby, Iowa Draw** Subtotal Announced Total *Operating at actual capacity, approximately 5-10% over rated capacity. **Plants in bordering counties of other states with 50% use assigned to Iowa corn.
8 Corn consumption and storage Distillers Grains storage 2.62%
9 Corn sources for ethanol plants 62% of corn is purchased directly from farmers 16 plants purchase >50% of corn from farmers 5 plants tied to local elevators; 60-95% of corn comes from elevator

11 Farm and Commercial Storage Iowa has 1.65 billion bushels of on-farm storage (NASS, 2005) Iowa has 1.08 billion bushels of commercial storage (IDALS – Grain Warehouse Division, 2006) Total – 2.73 billion bushels –Plant managers encourage on-farm storage; premiums structured for future delivery (2) –On-farm storage less likely to be built where cash rented land is prevalent –Plan to include questions about on-farm storage in Iowa Rural Life Poll in
12 Corn Quality US Grade #2 Yellow Corn - no premium for better quality or special traits Moisture limit: 17% (a few take 18%) Test Weight low limit: 54 lb/bu Damage limit: 10% (discount from 5%) Broken Corn: 12% max Producers must meet #2YC quality spec to sell to ethanol plants. Otherwise, corn is rejected.
