Log of the agronomic activities on the GLBRC sites. See here for an interactive version

This datatable is part of the Agronomic Log Queries - GLBRC Biofuel Cropping System Experiment dataset.

It contains specific queries of agronomic activities carried out on the Biofuel Cropping System Experiment, prepared from the Agronomic Log. The Agronomic Log contains all agromonic activities for multiple experiments. Contact the GLBRC Sustainability Information Manager if you need additional information from the aglog.

2025-11-24 KBS Corn Stover Harvest: Jarrod Rhoades mowed corn stover in G1 main plots: Reps 3, 2, 5, 4, & 1. Corn stover was mowed into windrows so that they could be bailed. The 6 rows (15 ft) in the west micro-plots of each rep were not mowed. Equipment Used: JD 7420a tractor and Loftness 15 ft Draper Windrower Shredder. Joe Simmons bailed corn stover with Krone 1270 square baler. Reps 2, 3, 4, 5, & 1. Equipment Used: JD 7520 tractor with Krone 1270 square baler. Ethan Rocklin removed bales from plots: Equipment Used: JD 7420(b) tractor (with loader) was used to move/load bales. Equipment Used: Dodge truck and gooseneck trailer were used to move and weigh bales. Portable scale was put on the rear of gooseneck and bales were place on scale to obtain weight. Bales were used as hunting blinds in the BCSE site.
2025-11-04 KBS Apply herbicide to weeds in barley, rye, and wheat. Wind 5.8 mph from SW, 56.8 F.
2025-10-31 KBS Harvest GLBRC main site treatment G3 (sorghum) and G6 (miscanthus) main plots. Equipment Used: All plots were harvested with the JD 7350 self-propelled forage harvester equipped with a JD 676 cutting head. Plant material was chopped into a Gnuse forage wagon that is fitted with load cells to determine weight of harvested biomass. Cutting height of remaining plant stubble was 4-6 inches in all reps. 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 replication.
2025-10-30 KBS Harvested biomass in G4, G5, G7, G9, and G10 plots, all reps. Harvested the main-plot area. Wet grab samples were collected and placed in the Grieve plant drier to determine percent moisture in the biomass. 2023 and 2024 were the first two years that all the biomass was mowed with the JD discbine and chopped with the JD self-propelled chopper equipped with a 'hay (biomass) pick-up head'. In past years the biomass was 'direct' cut with the JD selp-propelled chopper equipped with 'kemper' direct harvesting head. See notes relating to the harvesting equipment heads under the JD 7350 sel-propelled harvester 'chopper'. In 2025 the 7350 self-propelled forage harvester/chopper was equipped with a JD 630B Windrow Pickup Head with Finger Auger, 3.0 Meter (9.8 ft) Wide. Biomass was chopped in to the GNUSE 12 ton forage wagon. The GNUSE wagon is equipped with load cells so that it can weigh biomass in the field directly on the wagon. G7R3 was mowed west to east to determine if mowing the plot perpendicular would pick up more lodged biomass than mowing it North to South. Mowing west to east did not help pick-up more of the lodged biomass so the remaining replications were all mowed going north to south.
2025-10-29 KBS Harvested GLBRC BCSE G3, G4, G5, G6, G7, G9, and G10 micro-plots (fertilized and non-fertilized plots). Harvested with JD 6140 tractor using the 7.5 ft wide Kemper head and custom biomass weighing system with 3 Rice Lake load cells, RL32018 4k. The middle 7.5' of each micro-plot were harvested. Plot weights were obtained from the on-board Rice lake scale. Cutting height of plant stubble was 4-6 inches. Grab samples from each rep was placed in burlap bags, weighed for wet weight and placed in plant dryer and will be reweighed to determine percent moisture for each treatment and replication.
