Name: John Deere 7420a Tractor

2010-10-22 Harvest Baled corn stover from all reps of G1 and G3 in the GLBRC. Plots were first cut and windrowed with John Deere 4995 Discbine. Windrowed stover material was collected and baled with the JD 7420a tractor and JD 385 round baler. Bales were loaded onto a trailer and taken to the KBS Dairy to be weighed. Each bale had three moisture readings taken using a hand-held Farmex® DHT-1 Digital Hay Tester with 32” Probe.

2008-11-11 Planting Planted cereal rye on the LTER main site treatment 3 reps 6, 1, and 3 on Nov. 11, 2008. Planted T3 reps 2, 4, and 5 on Nov. 12, 2008. Planted with the JD7420(a) tractor and JD750 10 ft no-till drill. The variety of the rye was Wheeler. The desired seeding rate was 2 bushels/A. We ended up planting at 1.8 bu/A.

2008-11-12 Planting Planted c. rye in the LTER biodiversity study treatments B3, B4, and B16. Plot numbers for the biodiversity study: treatment B3: plots 111, 203, 306, and 403; Treatment B4: plots 104, 220, 307, and 404; Treatment B16: plots 101, 210, 308, and 416. Planted with the JD7420(a) tractor and JD750 10 ft no-till drill. The variety of the rye was Wheeler. The desired seeding rate was 2 bushels/A. We ended up planting at 1.8 bu/A.

2008-11-07 Planting Planted cereal rye on the LTER main site treatment 4 reps 5, 4, and 3 on Nov. 7, 2008. Planted T4 reps 2, 1, and 6 on Nov. 11, 2008.

2006-05-19 Mowing In the Biodiversity Study I flail mowed the rye in all replications of treatments B4 and B16, (B4 plots 104, 220, 307, and 404) (B16 plots 101, 210, 308 and 416). Flail mowing was completed with JD 7420(a) tractor and JD 115 flail shredder. Treatment B4 has a three year crop rotation of corn-soybeans-wheat with the use of cover crops. Treatment B4 plots where planted to corn in 2005 and had rye planted after corn harvest in the fall of 2005. Treatment B16 is annually planted to soybeans, no crop rotation, with the use of cover crops. Treatment B16 plots where planted to soybeans in 2005 and had c. rye planted after soybean harvest in the fall of 2005. The decision to flail mow the rye was based on the height and stage of development of the rye. The majority of the rye was between 18-31 inches tall and had developed the seed head. At the time of flail mowing the rye had not pollinated and therefore did not have viable seeds. I was concerned that if we had just chisel plowed some of the rye could have still matured enough to produce viable seeds. We did not want are cover crop of rye to become a weed problem in the annual crops.

2007-10-25 Planting Planted Pioneer 25R37 Soft Red Winter Wheat into LTER main site treatment 6, all reps. Planted reps 5, 3, 4, and 2 on October 25, 2007. Planted reps 1 and 6 on October 26, 2007. Planted with JD 7420a tractor and JD 750 no-till drill. Drill setting: 44. The drill meter (counter) indicated that 15.5 acres were planted. Sixty-one 50 pound bags were used (3,050 lbs). When finished 80 pounds of seed was removed from the drill. Seeding rate: 3050 pounds of seed used/15.5 acres = 197 lbs seeds/A, each pound of seed contained 10,000 seeds, therefore 197 lbs/A x 10,000 seeds/lbs = 1,967,742 seeds/A.

2007-11-08 Planting No-till planted organic cereal rye (no variety stated) into Biodiversity Study treatments B4, B5, and B16. Planted with JD 7420a tractor and JD 750 no-till drill. Drill setting: 32. The drill meter (counter) indicated that 1.0 acre was planted. A total of three 50 pound bags were used. When finished 20 pounds of seed was removed from the drill. Seeding rate: 130 pounds of seed used/1.0 acres = 130 lbs seed/A or (130 pounds of seed used/Acre)/(56 pounds/1 bu rye) (one bushel of rye equals 56 pounds) = 2.3 bu of rye/A. We did not have a count of the number of seed that each pound of the rye contained, therefore we can not say how many seeds were planted per acre. B4 plots: (104, 220, 307, and 404); B5 plots: (114, 217, 312, and 405); B16 plots: (101, 210, 308, and 416).

2011-05-04 Planting Planted Canola in the GLBRC Main Site treatment G4, all replications (reps 3, 5, 4, 2 & 1). Planted with the JD7420a tractor and the JD750 10' no-till drill. Actual seeding rate was 9.9 lbs/A (18.8 lbs in 1.8A total planted) and was planted at a depth of 1/2”-3/4”. Settings on the drill were #2 on the seeding rate and #2 on the depth. All plots seeded in 9 passes of the drill giving 90' width of planted area; planting started in the southwest corner of each plot. The variety of seed used was DeKalb Genuity Roundup Ready Canola DKL72-55. This variety is listed at 80,070 seeds/lbs which indicates we seeded at 792,693 plants per acre.

2011-05-24 Mowing Flail mowed red clover in the LTER treatment 4, all reps: 1, 2, 3, 4, 5, and 6. Flail mowed with JD 7420a tractor and JD 115 15' flail mower. We had such good growth of the red clover that we decided to mow the red clover before chiseling plowing the T4 plots. Without flail mowing we did not think the red clover would had been incorporated into the soil. Flail mowing prevented large clumps of clover on top/in the soil, preventing the clumps of clover allows for a better seedbed preparation.

2011-05-31 Mowing Flail mowed the LTER Main Site Biodiversity Study, all non-wheat treatments that still had cover crops except the fall fallow, which was not mowed. The following treatments were flail mowed: B4 (plots 104, 220, 307 and 404), B5 (plots 114, 217, 312, and 405), B7 (plots 105, 219, 305, and 417), B8 (plots 118, 214, 310, 408), B14 (plots 115, 204, 304, and 414), B15 (plots 112, 213, 301, and 415), and B16 (plots 101, 210, 308, and 416). All plots were flail mowed to approximately 6-8” height across the entire field. Mowed with the John Deere 115 flail mower on the John Deere 7420a tractor.

2011-06-15 Fertilizer Application 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

2012-11-13 Mowing Flail mowed the east 15' of the no-till Interaction plots. No herbicide is applied to the east 15' of the no-till plots allowing weeds to become very thick. Not wanting to run the combine through weeds we decided to mow strips with the John Deere 115 flail mower on the John Deere 7420a tractor.

2012-11-13 Mowing Flail mowed the LTER Main Site treatment T8's all replications (rep 1, rep2, rep3, and rep4). Mowed with the John Deere 115 flail mower on the John Deere 7420a tractor.

2012-11-20 Planting Planted winter wheat into all 16 of the interaction plots. Wheat was soft red winter wheat, Pioneer 25R39, treated seed. All plots were planted at the same time due to soil conditions and consistency of planting depth between the two types of plots. Seeding rate was roughly 1,625,000 seeds/A. Are goal was to plant 2,000,000 seeds/A. Seed was planted with the JD1590 no-till drill set on population setting (41) at a depth of 1/4” to 3/4” pulled by JD 7420a tractor. Average planting speed was 3.5mph. All plots were planted in six passes.

2012-11-14 Mowing Flail mow bait crop in GLBRC where corn was planted. Mowed with JD 15' 115 flail mower pulled by JD 7420a tractor to help decomposition of corn stalks.

2012-11-26 Planting No-till seeded red clover at 13.3 lbs/A (14.9 kg/ha) in the LTER Biodiversity study, treatments B3 (111, 203, 306, 403), B6 (107, 207, 317, 406), B15 (112, 213, 301,415). Clover was seeded slightly heavy due to late planting and soil conditions. Variety of clover was a certified organic medium red clover obtained from DKB Farms & Services LLC located out of Columbiaville MI. Product ID: 11449 stated it had 98.4% pure seed, .59% inert matter and a germination rate of 91%. Planting depth was 1/4 inch deep and seeding population on seeding box was set at 5. Planted with the JD7420a tractor and JD1590 15ft no-till drill. We did not have a count of the number of seed that each pound of the red clover contained, therefore we can not say how many seeds were planted per acre.

2012-11-26 Planting No-till planted cereal rye at 144 lbs/A (161kg/ha) in the LTER Biodiversity study, treatments B3 (111, 203, 306, 403), B5 (114, 217, 312, 405), and B16 (101, 210, 308, and 416).

Planting depth was 1/4 - 3/4 inch deep and drill population setting was #36. Planted with the JD7420a tractor and JD1590 15ft no-till drill. We did not have a count of the number of seed that each pound of the rye contained, therefore we can not say how many seeds were planted per acre. However, the 144 lbs/A (since 56 lbs seed/A = 1 bushel) works out to 2.6 bu/A.

2012-09-05 Mechanical Weed Control Flail mowed LTER Main Site Biodiversity study wheat plots; treatments B5:(114, 217, 312, 405), B8:(118, 214, 310, 408), B11:(110, 216, 309, 411), B14:(115, 204, 304, 414), B17:(116, 211, 302, 417), B20:(120, 215, 318, 420). Severe drought through the summer months inhibited establishment of clover cover crops in treatments B5:(114, 217, 312, 405), B8:(118, 214, 310, 408), B17:(116, 211, 302, 417). Weeds had established and were suppressing the growth of clover crop. Goal of flail mowing plots was to control weeds such as ragweed which allowed for late season clover growth. Wheat plots that did not have clover cover crop were mowed strictly for weed control. This was done using JD 7420a tractor and JD 115 flail mower.

2012-10-02 Mowing Flail mowed LTER Main Site treatments 1 & 2 micro plots, all replications. No herbicide is applied to these micro plots leaving weeds to thick to run through combine. Goal was to mow weeds down before main plot was harvested so the combine did not have to harvest the weeds. This was done with JD 7420a and JD 115 flail mower.

2012-10-02 Mowing Flail mowed GLBRC bait crop corn residue as well plots in rep 6 and near the brown house. Corn stalks were mowed to assist in decomposition of residue. Plots in rep 6 and near the brown house were mowed due to the crops lack of growth caused from severe drought through summer months. This was done using JD 7420a and JD 115 flail mower.

2012-11-20 Planting Planted winter wheat into the T8-NT plots. Wheat was soft red winter wheat, Pioneer 25R39, treated seed. The four plots were drilled using a JD1590 no-till drill at a depth of 1/4” to 3/4” pulled by JD 7420a tractor. Seeding rate was 1,625,000 seeds per acre (setting #41 on the drill). All plots were planted in three passes.

2012-11-21 Planting Planted winter wheat into lysimeter field. Wheat was soft red winter wheat, Pioneer 25R39, untreated seed. A total of 7.7 acres were planted using 1179 lbs of seed. Pioneer 25R39 (untreated seed) has 12,000 seeds/lbs. Seeding rate worked out to be 1,837,400 seeds/A. Population rate on planter was set at 41 and wheat was planted at a depth of 1/4” to 3/4”. Planted by JD 1590 no-till drill pulled by JD 7420a tractor. Average planting speed was 4 mph.

2012-11-21 Planting Seeded Soft Red Winter Wheat into Biodiversity treatments B4 (104, 220, 307, 404), B7 (105, 219, 305, 407), B10 (117, 209, 320, 410), B17 (116, 211, 302, 417), and B20 (120, 215, 318, 420). Plots in rep 4 were planted the day before on 11/20 to get drill depth set up. Seeding rate was roughly 1,625,000 seeds/A. Our goal was 2,000,000 seeds/A Planting depth was 1/4” to 3/4” deep with a speed of 3-3.5 mph. Seeded with JD7420a tractor and the JD1590 no-till drill. Seeding rate was calculated from planting the interaction plots, T8-NT plots and these 20 plots in the Biodiversity Study. All three studies added up to 7.5 acres. 1400 lbs of seed (28 bags) were put in the drill with 292 lbs being left over at the end of planting. This gave us a total of 1108 lbs of seed planted within 7.5A working out to equal 1,625,000 seeds/A.

2012-10-12 Planting No-till planted cereal rye at 105 lbs/A (117.89 kg/ha) in the GLBRC G4 treatment. Rye variety was not stated on the tag. Seed was obtained from the CISCO companies, Indianapolis, IN, Lot # WGB11432, by why of Battle Creek Farm Bureau, Climax location. Stated germination rate was 88%. Planting depth was 1 inch deep and drill population setting was #26. Planted with the JD7420a tractor and JD750 10ft no-till drill. We did not have a count of the number of seed that each pound of the rye contained, therefore we can not say how many seeds were planted per acre. However, the 105 lbs/A (since 56 lbs seed/A = 1 bushel) works out to 1.875 bu/A. We put 4 bags of seed in the drill (4*56=224 lbs). We removed 45 lbs of seed from the drill after planting. The drill meter indicated that we planted 1.7A. (224-45=179 lbs) (179/1.7=105 lbs/A). Drill setting: 26.

The goal was to work up and kill any weeds that had grown from previous tillage. All plots were finished to a 4-5” depth with speed of 3-4 mph.

2014-09-30 Soil Preparation Field cultivated LTER Main Site Biodiversity Study continuous wheat treatments B17, all reps: (plots 116, 211, 302, 417) and B20, all reps: (plots 120, 215, 218, 420). Plots were soil finished with the JD 7420 tractor and the Glenco field cultivator a total of two times making 4 passes each time. The goal was to work up and kill any weeds (mainly quack grass) that had grown and try to prevent further growth. All plots were finished to a 5-6” depth with speed of 4-7 mph. Because treatments B17 and B20 are continuous wheat (without crop rotation) we have problems with quack grass growing so thick in these plots that we do not have much wheat to harvest from these plots. The goal will be to preform tillage in these plots from now unit the wheat needs to be planted later this fall (October) and see if we can reduce the amount of quack grass growing in these plots next spring (a type of short term fallow treatment).

2016-04-28 Soil Preparation Chisel plowed and soil finished the tilled micro-plot areas in field M1 at Marshall Farm. Plots were chiseled and soil finished twice in the direction of north to south. Tilled micro-plots are the west side micro-plots (No-till micro-plots are on the east side). Not sure which day these micro-plots were tilled. We know that M1 was sprayed for burn-down on April 23, 2016 and was planted on April 30, 2016. These micro-plots were tilled before the field was planted. So we tilled the micro-plots the week of April 25-29, 2016.

2013-05-02 Soil Preparation Chisel plowed and soil finished the tilled micro-plot areas in field M1 at Marshall Farm. Plots were chiseled and soil finished twice in the direction of north to south. Tilled micro-plots are the west side micro-plots (No-till micro-plots are on the east side). Not sure which day these micro-plots were tilled. We know that M1 was planted on May 9, 2013 and was sprayed for burn-down and pre-herbicide application on May 11, 2013. These micro-plots were tilled before the field was planted. So we tilled the micro-plots the week before May 9, 2013. Not sure if Brandon and Justin Mezo, Terry Tilley and Justin Mezo completed these field activities or if Justin completed both chisel plowing and field cultivating. I think it was Brandon and Justin Mezo that completed these field activities.
