Planted Pioneer 35Y55 corn at 30K seeds/A (74K seeds/ha). 35Y55 is a Bt variety for protection against corn borer. Row spacing: 30 inches (76.2 cm). Planting depth was 2 inches (5 cm). Soil temperature at planting was 60 degrees F. Previous crop in 2003: corn. Lorsban 15G (chlorpyrifos) insecticide was applied at 8 oz/1,000 foot of row (8.7 lbs/A or 9.77 kg/ha). The six border rows on each side of both studies and plot area for both studies were planted with 35Y55. However, as part of an insect resistance management plan the area between the irrigated and non-irrigated studies was planted to Pioneer 35Y54 corn variety. 35Y54 is a non Bt variety. A total of twelve rows were planted to 35Y54. Lorsban was applied to the entire study area and the twelve rows between studies. The first six border rows on the west side of the non-irrigated study did not have any Lorsban applied to them. Leaving six rows without the Lorsban provides an area to set up the corn planter and check planting depth without the insecticide being present.

All East-West alleys were worked first on 3/31 and 4/1 and seeded at 660 lbs grass / acre (15 lbs/1000 sq ft). Following East-West alley seeding, North-South alleys were worked as described and seeded, starting on 4/1 and finishing on 4/2. Seeding was again conducted using two passes of the Brillion seeder but the seeding rate was lowered to 310 lbs grass / acre (7.1 lbs/1000 sq ft). A higher seeding rate on the E/W alleys were thought to help promote quick establishment to allow plot planting, without damage to the alleys, later this spring. Seed was obtained through Winfield Solutions LLc, St. Paul MN and was Tradename EARTHCARPET GREEN RESISTOR TURFGRASS BLEND, which is a mixture of Oregon Certified Seed of SR8650 Tall Fescue (49.89%), Grande II Tall Fescue (24.91%) and SR8550 Tall Fescue (24.83%) [inert matter 0.37%]. Approximately 8,500 lbs of seed was used to plant the approximately 15.25 acres of alleys. Weather conditions were mostly sunny, temperatures varying from 60s to 80°F, winds varying from calm to gusts of 20+ mph. Following planting on 4/2, 0.25 inch of rain was received on the night of 4/2-4/3.

2008-06-04 Planting Hand planted miscanthus in the GLBRC. We had extra miscanthus rhizomes so we planted what would have been the G6R6 plot area (the southwest corner of intensive field site). The rep 6 area would have been the south part of the field but we decided to have that area for other studies, not 6 reps of the main site treatments. We planted the miscanthus for two reasons: 1. we will have a nursery of miscanthus if we need replacement plants for the intensive plots. 2. we will have an area to conduct other experiments on miscanthus that we can not conduct in the intensive plots without interfering with the integrity of the plots. Row spacing: 30 inches. Spacing within row: 30 inches. Total rows within each plot: 36. Total rootstock within each row: 52. Planting depth: 4”. Before planting Jim Stoneburner soil finished this plot area with JD 7520 tractor and JD 726 soil finisher.

Before this date we would plant a crop next to 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.

2004-10-15 Soil Preparation Chisel plowed the LTER east - west alleyways around the T4 plots. Because T4 plots are organic we could not spray them on September 30, 2004. I think that we sprayed half of the alleyway and chisel plow the other half of the alleyway or chisel plowed 1/3 of the alleyway and sprayed 2/3 of the alleyway. We only chisel plowed around T4 plots, all other plots had the grass and weeds sprayed.

2014-08-25 Soil Preparation Chisel Plowed 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 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).

The fertilizer 19-17-0 was made by mixing 50% 28% UAN fertilizer and 50% 10-34-0 fertilizer. Planting depth for the corn was 2-2.25 inches. The corn was planted in 30 inch rows.

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.

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.
