Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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.

| 2026-06-16 | KBS | G1 | G1R3 | Fertilizer UAN 28% | Applied UAN 28% fertilizer to LTER T2 (rep 6, 3, 2, 4, 5, and, 1), T1 (1, 5, 4, 2, 3, and 6), T8nt (all reps) and to GLBRC G1 (reps 5, 4, 3, 2, and 1). Fertilizer applied at 50 gallons per acre, supplying 150 lbs of Nitrogen. This combined with the 30 lbs of Nitrogen from the starter fertilizer provide a total of 180 lbs of Nitrogen. Fertilizer applied to T2 plots on 6/15/26, except for 36 rows on the East side of T2R1. Which were finished on 6/16/26. Orifice size used was 91/63. | ||||
