Sprayed fertilizer in the GLBRC Main Site Treatments G4, 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 17 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 2 passes of the sprayer. Treatment G10 was fertilized on only 15' on west side of plot. Conditions: see application record. Equipment Used: John Deere 6140R tractor with a three point mounted Top Air sprayer equipped with a hydraulic centrifugal sprayer pump and Ag Leader Rate Controller.
