Name: John Deere 4400 Tractor

2010-06-01 Fertilizer Application Fertilized the GLBRC Main Site Treatment G8 Poplar trees, all replications (reps. 2, 1, 4, 5, and 3). Trees fertilized with ammonium nitrate at 140 lbs N/A (412 lbs NH4NO3/A). Fertilizer was applied in 2 passes using a three-point mounted Gandy Orbit-Air fertilizer applicator with a 6.5' boom length on which were mounted 8 nozzles; however, the nozzles were set to apply the fertilizer over the entire 8' distance between tree rows. Calibration rates were determined based on an 8' boom length. The Gandy was pulled by a John Deere 4400 compact tractor. The Gandy was calibrated to apply 1.125 lbs /min/nozzle when traveling in drive setting A at maximim velocity with 2500 engine RPMs. For each treatment plot, a 15' unfertilized microplot area was left on the southern side of the plot. Because of the staggered planting arrangement, either 3 or 4 trees in each row were in the microplot. Weather conditions: initially partly cloudy to sunny at end. Temperatures 68-80 degrees F. Initial relative humidity was 92%. No wind.

2011-06-07 Fertilizer Application Fertilized LTER Main Site treatment T5 replication 4 only with 27% ammonium nitrate (YaraBela CAN-27 granular). Trees were fertilized with ammonium nitrate at 140 lbs N/A (518 lbs CAN-27/A). Fertilizer was applied in 2 passes using a three-point mounted Gandy Orbit-Air fertilizer applicator with a 6.5' boom length on which were mounted 8 nozzles; however, the nozzles were set to apply the fertilizer over the entire 8' distance between tree rows. Calibration rates were determined based on an 8' boom length. The Gandy was pulled by a John Deere 4400 compact tractor. The Gandy was calibrated to apply 0.784 lbs/min/nozzle when travelling 3.0 mph in drive setting A at maximum velocity with 2800 engine RPMs. For each treatment plot, a 50' unfertilized microplot area was left as the north 50' of the plot. Because of the staggered planting arrangement of the trees, either 10 or 11 trees in each row were in the microplot. Weather conditions: Sunny, temperatures up to 92 degrees F. No wind.

2011-07-29 Fertilizer Application Fertilized the LTER Main Site Treatment T5 fertilizer microplots (all replications: 5, 1, 2, 3, 4, and 6) located as the north 50 feet of the T5 main plots. Only the microplots corresponding to treatments N2 (50 lbs N/acre, single application in 2011), N3 (100 lbs N/acre, single application in 2011), N4 (50 lbs N/acre, annual applications starting in 2011), N5 (100 lbs N/acre, annual applications starting in 2011) were fertilized. Fertilizer was applied as granular CAN27 which is a 27% ammonium nitrate + calcium fertilizer. For the 50 lbs N/acre microplots, the fertilizer was applied in a single pass of the applicator. For the 100 lbs N/acre microplots, the fertilizer was applied in two passes of the applicator. Applied using the JohnDeere 4400 garden tractor and the small Gandy air-seeder. The Gandy was calibrated to apply the equivalent of 8' of width of fertilizer, but into a 6' wide pass. All microplots were 6 rows of trees wide (approximately 47.8'). The five alleys inside the microplots received the full amount of fertilizer. The two outside alleys received only 1/2 rate of the fertilizer and then only on the 1/2 of the width of the alley corresponding to that microplot.

Only the microplots corresponding to treatments N4 (50 lbs N/acre, annual applications starting in 2011), and N5 (100 lbs N/acre, annual applications starting in 2011) were fertilized. Fertilizer was applied as granular CAN27 which is a 27% ammonium nitrate + calcium fertilizer. For the 50 lbs N/acre microplots, the fertilizer was applied in a single pass of the applicator.

The Gandy was calibrated to apply the equivalent of 8' of width of fertilizer, but into a 6' wide pass (122.7 g/nozzle/15 seconds). Application speed was 2.9 mph. Weather was mostly sunny, 63 degrees F, approximately 52% relative humidity. Inside the tree canopy, wind was calm. All microplots were 6 rows of trees wide (approximately 47.8'). The five alleys inside the microplots received the full amount of fertilizer. The two outside alleys received the fertilizer only on the 1/2 of the width of the alley corresponding to that microplot and the applied amount corresponded to only a 4' width.
