Fertilizer Applications by Year and Treatment
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.
