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.

| 2024-10-29 | KBS | Harvest GLBRC main site treatment G2 (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. |
| 2024-10-28 | 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'. The 7350 self-propelled forage harvester/chopper is equipped with a JD 676 Rotary Rowless Header, (Kemper Harvesting Head), 15 ft (4.57 meter) wide, or 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. |
| 2024-10-28 | KBS | Harvested GLBRC BCSE G2 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. The middle 7.5' of each micro-plot were harvested. Plot weights were obtained from the on-board Mettler Toledo 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. |
| 2024-10-28 | KBS | Harvested GLBRC BCSE 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. 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. |
| 2024-10-28 | KBS | Soil finish fields and plant MCIA 357 wheat at 100 lbs. per acre (1.4m). Seeding depth was 1 inch. |
