Comment:
Applied 28% liquid nitrogen fertilizer to LTER T6 plots (reps 1, 2, 4, 3, 5, and 6) at 16.7 gallons/A which provides 50 lbs/A nitrogen. For this year there was no -N micro plot, the entire plot area was fertilized, except the bromegrass microplot.
Applied 28% liquid nitrogen fertilizer to GLBRC Switchgrass fertility study according to the following gradient.
SWF1: 0 lbs N/A = 0 gal 28%/A
SWF2: 25 lbs N/A = 8.4 gal 28%/A
SWF3: 50 lbs N/A = 16.7 gal 28%/A
SWF4: 75 lbs N/A = 25.3 gal 28%/A
SWF5: 100 lbs N/A= 33.7 gal 28%/A
SWF6: 125 lbs N/A = 42.1 gal 28%/A
SWF7: 150 lbs N/A = 50.5 gal 28%/A
SWF8: 175 lbs N/A = 58.9 gal 28%/A
All applications done with Chafer stream bars, except for SWF2, which were done with Tee Jet 015 green SJ3 nozzles.
