Soybean ground pile?!

Got Storage ?! Stored Grain Management Sanitation Bin Loading practices Aeration Safe Monitoring Web sites for other information

Sanitation Equipment Combine(s) Carts/truck beds Handling equipment Dryers Bins

Sanitation Outside the bins Remove spilled grain Mow weeds to reduce rodent activity

Sanitation Inspect bins Look for daylight shining through holes in roof and walls Seal bottom ring to prevent air leaks Repair as needed

S.L.A.M. Stored Grain Management Sanitation Bin Loading practices Aeration Safe Monitoring Web sites for other information

Bin Loading Don’t overfill the bin

BAE Bin Loading  Manage trash and fines  Control grain damage by combine  Run augers full and ASAP  Clean grain before storage  Use a spreader to fill the bin  Core the bin to remove fines/trash from the center

BAE Manage Trash and Fines

BAE Core after Filling to Remove BCFM

BAE Moisture Migration in Winter 65 O F 45 O F

BAE Grain Spoilage from Moisture Migration  Uniform Temperature Prevents moisture migration Preserves product quality

Questions? Thanks for your attention…

What is REAP / GOAP? The Rural Energy for America Program (REAP) is offered through the USDA Rural Development The Kentucky Ag Development Fund provided money for state projects Provides assistance to agricultural and rural small businesses for energy efficiency improvements or renewable energy installations

Past Projects—Example 1 Grain Dryer  Controller upgrade – $3,078 per year savings – 14.0 year payback Controller upgrades typically yield better paybacks due to lower initial cost and high price of over drying grain

Past Projects—Example 2 Grain Dryer  Replacement of old dryer with new energy efficiency model – $1,431 per year savings – 20.2 year payback Old Dryer New Dryer
