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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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

| 2020-05-23 | KBS | G1 | G1R3 | Ammonium sulfate (AMS) | 4.0 | 1.0 | Sprayed LTER CE1, CE2 plots, T8nt plots, Irrigated and non irrigated fertility study, lysimeter field, GLBRC perimeter bait crop ( outside 30' on north edge, inside 30' on south and east edge) far east plot in rep 6, and G1 all replications (5, 4, 3, 2, 1) for pre-emergence weed control where corn was planted. Sprayed with Roundup Powermax at a rate of 1 qt/A , ammonium sulfate at 3.4 lbs/A and Acuron at 3 qts/A. Weather conditions at the start 8:50 a.m. were cloudy/ fog, 59.4degrees F, 98.9% humidity with 1-2 mph south east winds. Conditions at the end 11:45 a.m. were partly cloudy, 70.2 degrees F, 68.9 % humidity, and 6-7 mph winds out of the south east. | ||
