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. |

Fertilized LTER Main Site Interaction Plots (field B3) with ammonium nitrate at 130 lbs N/A. Dry ammonium nitrate (34% N) was applied in two passes using a Gandy with a 15' boom. The 130 lbs N/A was equivalent to 382.4 lbs/A of total ammonium nitrate. Care was taken to not fertilize inside the lysimeter area. |

Fertilizer Application |
Fertilized LTER N-rate study (Irrigated and Non-irrigated fertility gradient study). Fertilizer applications were with 34-0-0 ammonium nitrate (granular) which supplied 34% nitrogen [purchased from Green Valley Agricultural Inc, Bangor, MI). A single pass of a Orbit-Air Gandy fertilizer applicator was used to broadcast and apply the correct amount of fertilizer. The amounts of nitrogen applied were as follows:
F1 (101, 203, 209, 404, 501, 603, 709, 804) 0 lbs N/A (0 lbs product/A);
F2 (102, 202, 304, 406, 502, 602, 704, 806) 15 lbs N/A (44.1 lbs product/A);
F3 (103, 205, 302, 407, 503, 605, 702, 807) 30 lbs N/A (88.2 lbs product/A);
F4 (104, 208, 305, 403, 504, 608, 705, 803) 45 lbs N/A (132.4 lbs product/A);
F5 (105, 204, 306, 401, 505, 604, 706, 801) 60 lbs N/A (176.5 lbs product/A);
F6 (106, 209, 308, 402, 506, 609, 708, 802) 75 lbs N/A (220.6 lbs product/A);
F7 (107, 201, 307, 408, 507, 601, 707, 808) 90 lbs N/A (264.7 lbs product/A);
F8 (108, 207, 303, 405, 508, 607, 703, 805) 110 lbs N/A (323.5 lbs product/A);
F9 (109, 206, 301, 409, 509, 606, 701, 809) 130 lbs N/A (382.4 lbs product/A). Guard plots were not fertilized. Time of application was between 10:00 and 12:15 p.m. Temperature at start was 72F, 47% relative humidity, skies were clear. Wind was calm between 1-3 mph at start from ESE. Equipment used: John Deere 7420b tractor pulling a Gandy Orbit Air applicator. The applicator was controlled by a Raven 660 automatic carrier control unit. Deflector were spaced 22.5 inches apart along the 15 foot boom length extending from the center of the drive-line off to the right side of the boom. For the Gandy/Raven set-up, the following were used: Density 60 lbs/cu ft; metering wheel 1 1/4” diameter (yellow); deflector spacing 22.5”; meter cal number 219; air pressure was 12 p.s.i. The Raven monitor automatically adjusted the application to maintain it at the set point regardless of ground speed; because of this, ground speed was adjusted to maintain a desired application rate of 2-2.5 lbs/minute/nozzle resulting in some treatments being fertilized at 1.2 up to 5.5 mph.

Fertilizer Application |
Applied nitrogen to both N-rate studies.
Applied ammonium-nitrate to the corn in the studies.
Row cultivated (twice) after the application of the ammonium-nitrate was applied. The reason we cultivated twice was to make sure we incorporated all the fertilizer into the soil. The second time we cultivated we went in the opposite direction of the first cultivation. |
