2018-06-01 Fertilizer Application The switchgrass was fertilized with 50 lbs/A nitrogen, at 16.67 gal/acre 28% UAN using the tractors Auto Trac and the sprayers rate controller. John Deere 6140R tractor with a Top-Air 3 point sprayer equipped with a hydraulic centrifugal sprayer pump. The sprayer was controlled by a Ag Leader/Raven Rate Controller. StreamJet SJ7 Fertilizer Spray Nozzles(0.3 gpm) are spaced 20 inches apart along the 45 foot boom. Weather conditions: sunny, mid 70's, with light winds(<4mph)
2018-05-30 Fertilizer Application Fertilized GLBRC Main Site Switchgrass Fertility Study (SWF: N-rate), all treatments and all replications. Fertilizer applied as 28-0-0 which supplied 28% nitrogen in the form of Urea-Ammonium Nitrate (UAN) (CAS #57-13-6 Urea, #6484-52-5 Ammonium Nitrate). The amounts of nitrogen applied were as follows: SWF1 = 0 lbs/A (108, 201, 307, 408); SWF2 = 25 lbs N/A (8.4 gal/A) (104, 206, 308, 407); SWF3 = 50 lbs N/A (16.7 gal/A) (102, 202, 302, 406); SWF4 = 75 lbs N/A (25.1 gal/A) (105, 208, 305, 405); SWF5 = 100 lbs N/A (33.5 gal/A) (101, 205, 304, 404); SWF6 = 125 lbs N/A (41.8 gal/A) (107, 207, 301, 403); SWF7 = 150 lbs N/A (50.2 gal/A) (106, 204, 306, 402); SWF8 = 175 lbs N/A (58.6 gal/A) (103, 203, 303, 401). Weather Conditions: mid 80's, 5-6 mph winds, sunny. Equipment used: John Deere 6140R tractor with a Top-Air 3 point sprayer equipped with a hydraulic centrifugal sprayer pump. A single pass of a boom type sprayer was used to broadcast apply the correct amount of fertilizer. The sprayer was controlled by a Ag Leader/Raven Rate Controller. StreamJet SJ7 Fertilizer Spray Nozzles(0.3 gpm) were spaced 20 inches apart along the 13.3 foot section of boom length in the center of each plot. The tractor was driven down between each plot to avoid running over yield area, and the sprayer extended off to the right side of the sprayer; 8 nozzles were used on the boom. The Ag Leader Rate controller was used to apply the different rates. The Ag Leader rate controller was set up for a 13.3 foot boom, and application rates entered for each treatment. speed was changed so that output of gallons per minute were within the range of the spray tips. Ground speed was manually entered into the rate controller, then the tractor was set to drive that speed. SWF2(8.4gpa - 6mph), SWF3(16.7gpa - 4mph), SWF4(25.1gpa - 3mph), SWF5(33.5gpa - 2.5mph), SWF6(41.8gpa - 2.0mph), SWF7(50.2gpa - 1.8mph), SWF8(58.6gpa - 1.5mph) SWF4 was set to incorrect higher speed, so a second pass was made to make up difference (6.2gpa - 6mph)
2018-05-23 Fertilizer Application 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 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: 2:30 p.m. sunny 76 degrees F, 41% humidity, 2-6 mph north wind. Conditions at 4:00 p.m. sunny 79 degrees F 28 % humidity, 0-5 mph north wind.
