A narrative of agronomic activities on the Cellulosic Biofuels Biodiversity Experiment.

This datatable is part of the Cellulosic Biofuels Diversity Experiment dataset. The Cellulosic Biofuels Diversity Experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 12 different cropping systems vary in species makeup and nitrogen input. Treatments include continuous corn, corn-soybean, two variations of switchgrass fertilized differently, a C3 – C4 grass mix, and prairie grasses native to Michigan with different numbers of species. Switchgrass varieties are Cave-in rock (commercial non-native) and Southlow commercial native). Prairie grasses include switchgrass (Panicum virgatum), big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), and Indian grass (Sorghastrum nutans),

Treatment plots are 9.1 by 27m (30 × 40 feet) replicated in each of 4 randomized blocks. The study site was established in 2008. Click on the image for a printable map of the study area.

2019-11-07 Flail mowed KBS LTER Cellulosic Biofuel Diversity Treatments CE1: 108, 202, 304, 401/ CE3: 105, 207, 301, 403. Ryan Anthony
2019-10-29 Harvested corn in the LTER CE study treatments CE1 and CE3 all replications. Harvested with the Kincaid plot combine. Plot weight and moisture were obtained from the on-board Mirus Harvest Master computer/software weighing system. Justin Mezo
2019-10-19 Harvested soybeans from the LTER, CE2 plots (112, 210, 312, 402). Four rows of soybeans were harvested from the middle of the east side of the plots. Plot weight and moisture content were obtained from the on-board computer/software weighing system, (Mirus software by Harvest Master, Juniper Systems). Justin Mezo
2019-10-17 Harvested LTER Cellulsic Biofuels Experiment (CE Study), all replications. Harvested the biomass crops i.e. switchgrass, C3 and C4 mix, and prairie grasses mixes. Harvested with JD 7330 tractor using the 7.5 ft wide Kemper head and Wintersteiger biomass harvester weighing system. The middle 7.5 ft was harvested out of the east side of each plot. Plot weight were obtained from the on-board Mirus computer weighing system, by Juniper Systems. Cutting height of plant stubble was 5 inches. Grab samples from each rep was placed in paper bags weighed for wet weight and placed in plant dryer and reweighed to determine percent moisture for each treatment and replication. Harvested treatments CE4: (plots 110, 203, 302, 404), CE5: (plots 106, 205, 303, 405), CE6: (plots 111, 204, 310, 406), CE7: (plots 107, 208, 309, 407), CE8: (plots 103, 211, 307, 408), CE9: (plots 102, 201, 308, 409), CE10: (plots 104, 206, 306, 410), CE11: (plots 101, 209, 311, 411), and CE12: (plots 109, 212, 305, 412). Started harvest in south west corner (C11:plot 101) and harvested in a serpentine pattern working to the east. Justin Mezo
2019-06-28 Sprayed Corn in GLBRC Main Site G1 all replications, Inner 30' on north perimeter and outer 30' on South and East perimeter bait crop, North half of productivity study, CE1 & CE3 all replications with Roundup Powermax at 1 qt/a and Ams at 3.4 lbs/A. Weather conditions at the start 2:30 p.m. were mostly sunny 84.1 degrees F, 62.1% humidity with 5-6 mph south west wind. Conditions at the end 4:17 p.m. were partly cloudy, 85.9 degrees F, 54.9% humidity, and 7-8 mph winds out of the south West. Justin Mezo
