All soybean plots were row cultivated at 3.5-4.0 mph, corn plots were cultivated at 4.0-4.5 mph, both with the rear shovels all the way back. Cultivated with the JD 7420a tractor and a six-row S-tine row cultivator.

2011-12-13 Harvest Harvested Corn Stover from all reps of G1 and G2. Harvested - Eastern 75 feet (30 rows) of each plot, expect for G2R1 the western 75 feet (30 rows) was harvested. The remaining 15' (6 rows) area unharvested is the stover non-removal microplot, located on the western 15' of each plot.

2011-11-21 Mowing Flail moved corn stubble in three studies: both N-rate studies, irrigated and non-irrigated, and the corn treatments iin the LTER CE Biofuel Study. Treatments and plots harvested in the LTER CE Biofuel Study were treatments CE1 plots: 108, 202, 304, 401; and CE3 plots: 105, 207, 301, 403. Corn stubble was mowed to assist in stubble decomposition. Flail mowing was completed using the JD 7420b tractor and JD 115 flail mower.

2011-12-17 Mowing Flail moved corn stubble in T2 and T1, all reps: T2 reps: 2, 3, 4, 5, 1, and 6; T1 reps: 6, 3, 2, 4, 1, and 5. Corn stubble was flail mowed to assist in stubble decomposition. Flail mowing was completed using the JD 7420b tractor and JD 115 flail mower.

2012-05-14 Mowing Flail mowed c. rye in the LTER main site treatments T3 and T4 plots, all reps: T3 (reps: 6, 3, 1, 2, 4, and 5), T4 (reps: 6, 1, 2, 3, 5, and 4). Flail mowed with JD 7420b tractor and JD 115 flail mower. We had such good growth of the c. rye that we decided to mow the c. rye before chiseling plowing the T3 and T4 plots. Without flail mowing we did not think the c. rye would had been incorporated into the soil. Flail mowing prevented large clumps of rye on top/in the soil, preventing the clumps of rye allows for a better seedbed preparation. The rye started to put a seed head on so we wanted to prevent any of the rye from producing seed before chisel plowing.

2012-05-15 Mowing Justin Mezo flail mowed cover crops, red clover and/or c. rye, in the LTER Biodiversity treatments B3 (111, 203, 306, 403), B4 (104, 220, 307, 404), B6 (107, 207, 317, 406), B7 (105, 219, 305, 407), B15 (112, 213, 301, 415), and B16 (101, 210, 308, 416). Flail mowed all corn and soybeans treatments that had cover crops growing in them. Flail mowed with JD 7420b tractor and JD 115 flail mower. Flail mowed with JD 7420b tractor and JD 115 flail mower. We had such good growth of the red clover and c. rye that we decided to mow the cover crops before chiseling plowing the treatments. Without flail mowing we did not think the cover crops would have been incorporated into the soil which would have caused large clumps of biomass creating a poor seedbed. Flail mowing prevents large clumps of red clover and rye on top/in the soil. Preventing the clumps of biomass (i.e. red clover and rye clumps) allows for a better seedbed preparation and better seed to soil contact.

2012-05-19 Soil Preparation Cultimulched the LTER Main Site Treatment T1, all reps, reps: 1, 2, 3, 4, 5, and 6. Because of cloddy soil conditions we thought the cultimulcher would remove the soil clods better than the rolling baskets on the soil finisher.

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.

2013-06-05 Mowing Flail mowed rye cover crop in Main Site GLBRC G2,G3,G4 micro-plots all replications. Because the rye was so tall and already headed out it was decided to flail mow the plots instead of spray them due to coverage issues.

2013-07-13 Fertilizer Application Fertilized the LTER Main Site treatment T6 alfalfa, all replications (reps 1, 2, 3, 4, 5, and 6) with potash. A total of 270 pounds /A of product (0-0-60) which supplied 162 lbs/A of K2O. Applied in a single application of using the John Deere 7420b tractor traveling 2.2 mph and a Gandy Orbit-Air fertilizer applicator controlled by a Raven 6000 which monitored the application and automatically adjusted the metering rate for changes in ground speed. For the Gandy/Raven set-up, the following were used: Density 68 lbs/cu ft; metering wheel 1 1/4” diameter (yellow); deflector spacing 22”; meter cal number 204; air pressure was 11 p.s.i.; Boom length 30 ft, nozzles 16-24 inches above the ground level. Replications 1 and 2 were done on Friday 7-16, reps 3,4,5, and 6 were done on Saturday. Rep 6 last 45 feet to the East had to be finished on Monday. LTER Main Site treatment T6 only got partial application of potash and that was 270 lbs/A potash (0-0-60) on July 13, 2013. Due to time restraints we were unable to get the remaining 230 lbs/A of potash on the alfalfa. Protocol was to apply 288 lbs/A K2O, however the 270 lbs/A of potash (0-0-60) put on in July supplied 162 lbs/A K2O out of the 300 lbs/A K2O that the protocol called for. Also (NO boron was added in 2013). Protocol had Boron being applied at 2 lbs/A.

2013-07-25 Harvest Baled straw from the LTER Main Site Treatments T1 and T2, all replications. Straw from the wheat harvest was cut one day before it was baled except for rep 6.

2017-04-19 Planting Replanted roundup ready alfalfa (Pioneer 55VR06) in the LTER Main Site T6 plots, all replications: 5, 4, 3, 2, 1, and 6. Fall seeded alfalfa had poor stand due to excessive amounts of biomass from the previous wheat crop. There were areas that came up great and then there were scattered bare spots. It was decided not to kill off original fall seeding but to replant in between the rows with a lower rate. Seeding Rate: Alfalfa was planted at 13.2 lbs/A pure live seed (alfalfa was planted at 16.2 lbs/A to achieve 13.1 lbs/A pure live seed given the seed coating material and germination percent). Tillage: No-till. Variety: Pioneer 55VR06-N221 P14F10 Roundup Ready Alfalfa Seed. Planting Depth: Alfalfa was planted 3/4 inch into the ground. While planting rep 6 it started raining with 5 passes to go. Finished planting the plot but the water caused the drill to become plugged. This was not known until the drill was cleaned out. After looking at alfalfa seedlings as they came up there was a difference in stand from where it had started raining. It was decided to replant that area again so 8 passes were planted in rep 6 on April 26, 2017 from the east side of the plot going west. This came out to be exactly 1 acre and seeding population was the same as the initial replant.
