  2. (Previous K-State studies) Anhydrous Application Rates Application Rate Item, % Dry Matter 0% 1.5% 3.0% Straw, (Laytimi et al., 1984, KSU) Crude Protein 3.9 7.7 8.8 IVDMD 47.2 57.3 56.7 ADF 55.6 56.5 56.3 DM Digestibility 45.6 53.8 52.7 CRP Hay (Clark County KS, 2011) Crude Protein 5.1 9.3 9.9 TDN 44.4 46.2 48.0 ADF 52.2 50.3 48.4

  3. 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)

  4. 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

  5. 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

  6. Observations • Demonstrations were well attended at all sites 30-45 persons • Condensation under plastic at some sites • Lack of an improvement in ADF/TDN • Some sites ADF increased, decreased TDN content

  7. Anhydrous Application Rates Application Rate Item, % Dry Matter 0% 1.5% 3.0% Crude Protein 3.50 8.60 10.83 ADF 51.38 52.33 52.10 IVDMD Laytimi et al., 1984 Crude Protein 3.9 7.7 8.8 ADF 55.6 56.5 56.3 IVDMD 47.2 57.3 56.7 ----In Progress---

  8. Nutrient Values • Crude protein • 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

  9. 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 $79.25 89.75 Ammoniation cost less hay $19.25 $29.75 Kuhl, 1981 as cited in OSU Publication #PSS-2243
