4. Objective Demonstrate the process of ammoniating forages to producers
Evaluate the application of different application rates of anhydrous ammonia under field conditions
1.5% of forage DM (30 lbs/ton)
3.0% of forage DM (60 lbs/ton)

5. Locations River Valley District- Robin Slattery
Meadowlark District-Jody Holthaus
Pottawatomie County-Austin Sexten
Kingman County- Matt Clark
Walnut Creek District-Jared Petersilie
KSU Stocker Unit

6. Procedures Bales were stacked in a 3,2 arrangement
Covered with 6 mil black plastic
Same plastic used at all sites
Forage samples were obtained
Prior to treatment
Approximately 14 days following anhydrous application

7. Observations
Demonstrations were well attended at all sites persons
Condensation under plastic at some sites
Lack of an improvement in ADF/TDN
Some sites ADF increased, decreased TDN content

8. Anhydrous Application Rates

9. Nutrient Values Crude protein Energy content
Consider ½ the increase in CP available
1.5% = 6.1 % CP
3.0% = 7.2 % CP
Energy content
Brands currently (50% TDN, 0.43 Mcal/lb NEm)
Traditional equations from ADF may not fit
Based off of IVDMD data

10. Estimated Cost of Ammoniation/ton
Application Rate
Item 1.5% 3.0%
Straw $60.00 $60.00
Stacking and handling $2.00 $2.00
Plastic ($236, 40 x 100, 6 mil) $6.75 $6.75
Anhydrous Ammonia ($700/ton) $10.50 $21.00
Total Cost $
Ammoniation cost less hay $19.25 $29.75
