Applied 28% nitrogen solution (28-0-0) at 16 gals/acre (150L/ha) to all replications of treatment 3 on the LTER main site winter wheat, (reps 6, 1, 3, 2, 4, & 5). Average height of the wheat was 2-3 inches. Total amount of fertilizer applied was 239 gals on 14.82 acres (6 hectares). One gallon of 28% fertilizer weighs 10.67 lbs. 48.18 lbs N/A (54.09 kg N/ha) was applied. The goal was to apply the nitrogen fertilizer at 3/5 (0.60) rate of the total amount applied to treatments 1 and 2. The protocol was to apply a total amount of 80 lbs N/A for treatments 1 and 2. We applied 32 lbs N/A in the autumn of 2003 so we were trying to apply another 48 lbs N/A in the spring of 2004 on treatments 1 and 2. The 3/5 rate of nitrogen applied to treatment 3 was based on the total annual amount, spring and fall amounts, of nitrogen, not just 3/5 of the nitrogen applied in the spring. Therefore, treatment 3 needed to receive to same amount of nitrogen in the spring as treatments 1 and 2 received, 80 lbs N/A * 0.60 = 48 lbs N/A. Treatment 3 did not receive any nitrogen in 2003. Weather Conditions: Mostly sunny with air temperature ranging from 77-79 degrees F. Relative Humidity was ranging from 30-37%. Wind was out of the west-southwest at 0-8 mph's averaging 3 mph's.

Fertilized the LTER Main Site treatment T2, replications 1, 4, 3, 2, 5, and 6 with 28-0-0 liquid fertilizer. Urea-Ammonium Nitrate (28-0-0) was applied at a total rate of 37 gal/A. Since 28% fertilizer weighs 10.65 lbs/gal, the 37 gal/A was the same as 110 lbs N/A. Fertilizer was knifed between the rows of corn using a 15' liquid fertilizer applicator. Plot T2R1 was fertilized completely on 13 Jun 2011. Plots T2R2, T2R3, and the west 1/2 of T2R4 received approximately 1/2 of the total fertilizer on 13 Jun 2011; however, at that time it was noticed that the volume of liquid which was being applied did not match the desired rate. Exploration determined that there was an equipment error and that the metering pump was not functioning correctly. At that time, it was determined that only about 1/2 the total rate had been applied. On 15 Jun 2011, a second application was made, to provide the amount which was missing, to make the total application equal to the 37 gal/A rate. The order of application for the entire treatment was T2R1, T2R4, T2R3, T2R2, T2R5, and T2R6. It is believed that the equipment error occurred approximately toward the end of plot T2R1 (rows 13-30 from the east edge of T2R1, fertilized on 13 Jun 2011) and the beginning of T2R4, although this could not be determined precisely. Fertilizer applied using the JD7420a tractor and the 6 row fertilizer applicator equipped with a John Blue GMP6055S ground driven pump |

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) |

Fertilizer Application |
Fertilized LTER N-rate study (Irrigated and Non-irrigated fertility gradient study) Corn plots.
Fertilizer applications were with 28-0-0 which supplied 28% nitrogen in the form of Urea-Ammonium Nitrate (UAN).
A single pass of a 28% applicator was used to knife in the correct amount of fertilizer. The 28% applicator has seven coulters where the 5 inside coulters apply a full target rate and the 2 outside coulters apply half of the target rate. The applicator is controlled by a rate controller as well as inline orifices.
Fertilizer was knifed roughly 4 inches into the ground on the rainfed plots and 6-7 inches on the irrigated plots.
A reminder that 30 lbs of N/A was applied at planting so total N/A applied will include the 30 lbs N/A applied at planting time (planting date was May 13, 2023).
The amounts of nitrogen applied were as follows:
F1 (101, 203, 309, 404, 501, 603, 709, 804) 0 lbs N/A;
F2 (102, 202, 304, 406, 502, 602, 704, 806) 0 lbs N/A;
F3 (103, 205, 302, 407, 503, 605, 702, 807) 30 lbs N/A (10 gal/A);
F4 (104, 208, 305, 403, 504, 608, 705, 803) 60 lbs N/A (20 gal/A);
F5 (105, 204, 306, 401, 505, 604, 706, 801) 90 lbs N/A (30 gal/A);
F6 (106, 209, 308, 402, 506, 609, 708, 802) 130 lbs N/A (43.5 gal/A);
This was the first year we changed the F7, F8, & F9 amounts: In past years the amounts were: F7 180 lbs N/A, F8 220 lbs N/A, and F9 260 lbs N/A. In 2023 F7, F8, & F9 were changed to: F7 200 lbs N/A, F8 250 lbs N/A, and F9 300 lbs N/A. We were afraid that we were missing the top yield with the top N so the LTER Executive Committee decided to up the total amount of N applied per acre for the F7, F8, and F9 treatments.
F7 (107, 201, 307, 408, 507, 601, 707, 808) 170 lbs N/A (57 gal/A);
F8 (108, 207, 303, 405, 508, 607, 703, 805) 220 lbs N/A (73.5 gal/A);
F9 (109, 206, 301, 409, 509, 606, 701, 809) 270 lbs N/A (90 gal/A).
Equipment used: JD 7420b tractor and liquid fertilizer applicator that was built by the FSC that was equipped with a rate controller and inline orifices. Orifices were changed accordingly with the application rate and treatments.
Weather conditions at 10:10 a.m. were mostly sunny 70.6 degrees F, with 8-13 mph Northeast wind, relative humidity 58.3%.

Fertilizer Application |
Fertilized Sorghum Nitrogen Rate Experiment
Fertilizer applications were with 28-0-0 which supplied 28% nitrogen in the form of Urea-Ammonium Nitrate (UAN).
A single pass of a 28% applicator was used to knife in the correct amount of fertilizer. The 28% applicator has seven coulters where the 5 inside coulters apply a full target rate and the 2 outside coulters apply half of the target rate. The applicator is controlled by a rate controller as well as inline orifices.
Fertilizer was knifed roughly 5-6 inches into the ground.
The amounts of nitrogen applied were as follows:
T1 (101, 205, 303, 407) 0 lbs N/A;
T2 (102, 203, 307, 403) 25 lbs N/A (8.4 gal/A);
T3 (103, 201, 306, 406) 50 lbs N/A (16.7 gal/A);
T4 (104, 207, 308, 408) 75 lbs N/A (25.1 gal/A);
T5 (105, 204, 301, 402) 100 lbs N/A (33.4 gal/A);

Fertilizer Application |
Applied 28% liquid nitrogen fertilizer to GLBRC G3 sorghum plots (reps 2, 1, 3, 5, and 4) and to GLBRC Sorghum N-Rate Study (South).
G3 Sorghum plots received 75 lbs/A actual nitrogen, which equals 25 gal/A of 28% fertilizer. This was done in two passes of 12.5 gal/A. Two passes were done to band the nitrogen in 15" rows instead of 30" rows that the applicator is normally designed for.
Nitrogen application in the Sorghum N-Rate study followed the below gradient with applied amounts of liquid 28% fertilizer:
SOF1: 0 lbs/A
SOF2: 25 lbs/A = 8.4 gal/A
SOF3: 50 lbs/A = 16.7 gal/A
SOF4: 75 lbs/A = 25.1 gal/A
SOF5: 100 lbs/A = 33.5 gal/A
SOF6: 125 lbs/A = 41.8 gal/A
SOF7: 150 lbs/A = 50.2 gal/A
SOF8: 175 lbs/A = 58.6 gal/A
All treatments were done with two passes for 15" row banding, except SOF2 (102, 203, 307, 403). Due to the low rate the applicator could not reach half of the desired amount to be split applied, therefore it was applied in one pass of 8.4 gal/A.
(see attached map)

Fertilizer Application |
Fertilize wheat and canola with 15 gallons 28% UAN, 5 gallons ATS, and 9.6 oz nitrification inhibitor per acre. Except a 15' strip, opposite where gas sampling occurs, was fertilized without nitrification inhibitor. Also, the Urin derived fertilizer micro plots in ASP5 were not fertilized. UDF to be added 3/27/2026.
The 15' strip in ASP5 R4, opposite where gas sampling occurs, was mistakenly fertilized with both fertilizer blends. Meaning is has received full fertilization, instead of just the first split application, and nitrification inhibitor at half rate. |
