Comment:
Fertilized the GLBRC Main Site Treatments G6, Miscanthus, all replications (replications 5, 4, 1, 2, and 3). All plots were fertilized with 50 lbs N/A applied as 28% N fertilizer (CAS #57-13-6 Urea, #6484-52-5 Ammonium Nitrate). 28% fertilizer weighs 10.67 lbs /gallon so the 50 lbs N/A worked out to 16.7 gal 28%/A. Each treatment plot was divided into two areas, an unfertilized microplot area 15' wide located on the west side of all the plots and the fertilized area which was the remaining 76.86' on the east side of the plot. The unfertilized 15' microplot received NO fertilizer. The fertilized 76.86' was fertilized at 50 lbs N/A applied in 3 passes of the sprayer. In all plots, for the first pass of the sprayer, only half the boom width (15') was used and a pass was made S to N along the W side of the fertilized area. The second and third passes were made with the full boom width (30'), with the second pass being S to N along the E side of the fertilized area and the third pass being N to S in the middle of that area. Conditions: Cloudy with air temperature 53 degrees F (11.7 degrees C). Relative Humidity was 93%. Wind was out of the east at 5 - 7 mphs. Time of application was between 9:00 a.m. and 11:30 a.m. Equipment Used: JD 5220 tractor traveling 3.4 - 3.7 mph (gear B3, 1450 - 1600 rpm) with a pull type Top Air sprayer equipped with a hydraulic centrifugal sprayer pump and a Raven 440 automatic carrier control unit. Turbo TeeJet 11003 nozzles were used, spaced 30 inches apart with a total boom length of 30 feet. 20 psi were used. Purpose of Application: Supply nitrogen to the treatment plots.
