Comment:
Applied UAN 28% Nitrogen fertilizer to G2 Sorghum plots (reps 1, 2, 3, 5, and 4). Applied a total of 25 gal/A, this was done in two passes of 12.5 gal/A each. 25 gal/A of 28% equals 75 lbs/A Nitrogen. Split applying in two passes makes the rows 15" wide instead of 30". This lines up better with the Sorghum planter. The no-nitrogen plot in G2R2 mistakenly had a partial pass of 12.5 gal/A applied, approx 60 feet long from the North end of the plot extending South.
