Fertilizer Applications by Year and Treatment — GLBRC Biofuel Cropping System Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
This is a description of the fertilizer applied to all replicates at the GLBRC Intensive Site.
This datatable is part of the Agronomic Log Queries - GLBRC Biofuel Cropping System Experiment dataset.
It dataset contains specific queries of agronomic activities carried out on the GLBRC Switchgrass Nitrogen-rate/Harvest 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.

| 2023-07-03 | KBS | G1 | G1R3 | Ammonium sulfate (AMS) | 4.0 | 1.0 | Herbicide application to GLBRC G1 all reps(1, 2, 4, 5, 3), Bait Crop area (corn and soybean), LTER T8nt plots, LTER CE Study corn (CE1 and CE3), and planted area of the Lysimeter field. RoundUp Power Max 3 at 30 oz per acre and Ammonium Sulfate at 3.4 lbs per acre were applied post-emergence to control grass weeds. Application in the GLBRC began at 10:15 am and concluded in LTER at 12:45 pm. Rate of spray was 20gal/acre on JD rate controller. John Deere 7420b tractor was used instead of 5220 due to concerns over the current height of the corn. REI is 4 hours, safe re-entry on Monday July 3 at 4:45 pm. Weather at 10:15 am: Temperature: 70.8°F Wind Direction: Northeast Wind Speed: 5.98 mph Relative Humidity: 90.6% Weather at 12:45 pm: Temperature: 76.5°F Wind Direction: Northwest Wind Speed: 3.83 mph Relative Humidity: 73.0% | ||
