Comment:
Sprayed fertilizer in the GLBRC Main Site Treatments G5, G6, G7, and G9, all replications. All treatments were fertilized with 50 lbs N/A applied as 28% N fertilizer. 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 unfertilzed 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; the first pass was centered 15' from the west edge of the main plot, but half the boom (over the microplot area) was shut off. Conditions: Cloudy with air temperature 68 degrees F. Relative Humidity was 83%. Wind was calm, but out of the south at 0 mphs. Time of application was between 11:30 a.m. and 4:15 p.m. Equipment Used: JD 5220 tractor traveling 3.5 mph (gear B2, 1650 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 11002 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.
