Narrative Agronomic Field Log

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.

2018-05-29 Fertilized LTER Cellulsic Biofuels Experiment (CE Study) treatment CE4 and CE6, all replications. Treatments CE4: (plots 110, 203, 302, 404); and CE6: (plots 111, 204, 310, 406). Plots received 50 lbs N/A with 17 gallons/A 28% N liquid fertilizer. 28% fertilizer weighs 10.67 lbs /gallon so the 50 lbs N/A worked out to 17 gal 28%/A. Weather conditions: 64 F cloudy and humid. Equipment Used: JD 5220 tractor with a pull type Top Air sprayer equipped with a hydraulic centrifugal sprayer pump and John Deere Rate Controller. Chafer stream bars were used, spaced 15 inches apart with a total boom length of 30 feet. 20 psi was used. Joe Simmons
2018-05-26 Planted soybeans in the LTER Main Site. Planted the N-rate (irrigated and non-irrigated studies), T8nt plots (all 4 reps), and CE study trt CE3 (plots 105, 207, 301, and 403). Equipment Used: Planted with the JD 7330 tractor and JD 1730 planter. Variety: Planted Pioneer P22T69R Roundup Ready soybeans. Planting depth: 1.25 inches. Row spacing: 15 inches. Joe Simmons
2018-05-26 Sprayed LTER N-Rate, T8nt plots, CE 3 with Valor. Valor was applied at 3.5 oz/A. Weather conditions: At the start 7:53 p.m. sunny 83 degrees F, humidity was 44 % with 3-6 mph west. End of application 9:40 p.m. sunny, 75 degrees F, humidity 59 %, with 1-4 mph north west winds. Justin Mezo
2018-05-08 Sprayed LTER T2, T8nt plots, CE 3 and pesticide pad with Roundup Powermax, 2,4-D est Lv4 and AMS. Roundup Powermax applied at 22oz/A, 2,4-D lv4 ester at 1 pint/A and Ammonium Sulfate (sprayable, CAS #7783-20-2) was applied at 17 lbs/100 gallons of carrier. Weather conditions: At the start 8:50 a.m. sunny 59 degrees F, humidity was 58.4 % with 5-9 mph south west. End of application 11:40 p.m. sunny, 68 degrees F, humidity 39.6 %, with 5-9 mph south west winds. Justin Mezo
2018-05-01 Planted corn in the GLBRC treatments G1, all reps (reps: 5, 4, 3, 2, 1), inside 30 ft on the south and east side of the bait crop, very west plot in rep 6, and CE1 and CE2 plots in LTER CE study. Equipment Used: JD 7330 tractor and JD 1730 planter. Brand and Variety Planted: Dekalb DKC51-38RIB seed corn at 32,000 seeds/acre (avg pop from monitor ). Planting depth: 1.5 inches. Row Spacing: 30 inches. Dekalb DKC51-38 RIB has a relative maturity of 101 days (2525 growing degree units to black layer). DKC51-38 is Roundup Ready Genuity Smartstax RIB (refuge in a bag) corn blend. Fertilizer Applied at Planting: 19-17-0 liquid fertilizer at 14.0 gallons/acre. The fertilizer was placed two inches to the side and two inches below the seed at planting. 14 gals/A of 19-17-0 supplies 29.22 lbs N/A and 26.14 lbs P205/A Justin Mezo
