Slide1: 

Manure Side-Dress Nitrogen Corn and Wheat Plots Glen Arnold, OSU Extension Educator Jon Rausch, OSUE State Extension Associate

Slide2: 

Manure No Manure

Animal Manure Applied to Growing Crops : 

Animal Manure Applied to Growing Crops Swine manure was applied as top dress nitrogen on wheat in late winter of 2006 & 2007 in replicated plots and yields compared to UREA. Swine manure was applied as side dress nitrogen to corn in June of 2005 & 2006 in replicated plots and yields compared to 28% UAN.

Slide5: 

Estimating the Value of Animal Manure Swine Manure Value per lbs/1000 gallon 1000 gal. Nitrogen 42¢/lb 19 lbs $ 7.98 P2O5 32¢/lb 8 lbs $ 2.56 K2O 20¢/lb 15 lbs $ 3.00 Total $13.54

Corn Plot Objectives: 

Corn Plot Objectives Determine if manure applied as side dress nitrogen during the growing season provides adequate nutrients to maintain yield Determine if application equipment is available to accurately side dress corn with liquid manure.

Corn Treatments Using an Aeroway Toolbar: 

Corn Treatments Using an Aeroway Toolbar Treatment 1 – incorporation of liquid swine nursery manure Treatment 2 – 99% liquid swine manure plus 1% 28% UAN (17 gallons of 28% UAN added to the 2400 gallon tank of swine nursery manure) Treatment 3 – 28% UAN injection of liquid nitrogen

Summary: 

Summary Swine manure has matched or exceeded wheat and corn yields compared to traditional inorganic fertilizers Equipment is available to accurately apply manure to growing crops More research is needed to find more efficient manure application methods and also seek to reduce potential compaction
