2007-10-31 Soil Preparation Chisel plowed around the LTER weather station. Chisel plowed to plant a permanent grass area around the weather station.

The data collected at the weather station was based (influenced) on the crop that was planted in the lysimeter field which was normally the same crop planted around the weather station. Because we will be planting grass around the weather station we will have the same crop (turf grass) influencing the data at the weather station.

2014-05-22 Soil Preparation Chisel Plowed the LTER Main Site T4 Reps: 1, 2, 3, 4, 5, 6 in that order. Chisel plow was power washed prior to entering organic plots. Plots were chisel plowed N-S and finished with 2 headland passes going E-W on both north and south side of each plot. Chisel plowed with JD 7520 tractor and JD 714 chisel plow at a speed of 4.5-5 mph. The tractor and chisel were both washed prior to entering the field to comply with the organic regulations.

2014-05-22 Soil Preparation Chisel Plowed the LTER Biodiversity Study treatments B4 (104, 220, 307, 404), B5 (114, 217, 312, 405), B7 (105, 219, 305, 407), B8 (118, 214, 310, 408), B15 (112, 213, 301, 415), B16 (101, 210, 308, 416).

Plots were chiseled with the JD 7520 tractor and the JD 714 chisel plow a total of two times. 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 3-4.5 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).

Reps 1 and 6 were chisel plowed on October 6, 2015 by Ryan Anthony and Justin Mezo. Field conditions allowed chisel plowing because the soil was dry enough to chisel plow. Some years we only soil finish after soybean harvest and plant wheat however this year we had time and field conditions allowed for the chisel plowing after soybean harvest before planting wheat. Chisel plowed with JD 7330 tractor and JD 714 chisel plow. Chisel plowed to a depth of 7-8 inches (17.8-20.3 cm). Plots were chisel plowed N-S across the field.

Replication 3 was soil finished once on October 2, 2015 with the JD 7520 tractor and JD 726 soil finisher. After soil finishing rep 3 we decided to chisel plot the remaining replications of treatment 1. We decided to chisel plow the remaining replication because the T1 plots had so much soybean stover remaining in the plots.

2016-04-29 Soil Preparation Chisel Plowed the LTER Biodiversity Study treatments: B2: (102, 206, 316, 402), B6: (107, 207, 317, 406), B9: (119, 205, 314, 409), B11: (110, 216, 309, 411), B12: (109, 202, 313, 412), B13: (113, 212, 319, 413), B15: (112, 213, 301, 415), B18: (108, 208, 311, 418), B19: (103, 218, 315, 419), B21: (100, 200, 300, 421). Chisel plowed all corn and soybeans treatments that had no cover crops growing in them. B6 and B15 were supposed to be corn stubble with clover cover crop however clover did not get planted in 2015 so these plots were also chisel plowed on April 29, 2016. Chisel plowed with JD 7520 tractor and JD 714 chisel plow.

B6: (107, 207, 317, 406), and B15 (112, 213, 301, 415) should have had cover crop but clover never was seeded in corn in 2015 so B6 and B15 plots were chisel plowed on April 29, 2016.

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.
