Agronomic Soil Chemistry — GLBRC Switchgrass Variety Experiment I
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic soil chemistry of surface soils (0-25 cm) from fertilized and unfertilized (starting in 2019) subplots of the GLBRC Switchgrass Variety Experiment I, as analyzed by the MSU Soil and Plant Nutrient Laboratory.
replicateThis datatable is part of the GLBRC Switchgrass Variety Experiment I dataset. This dataset contains data for the Switchgrass Variety Experiment I located on west side of the KBS GLBRC Intensive Field Site. Eight upland and four lowland varieties were planted in 2009-2010 in a complete randomized block design with 12 varieties (Treatments 1 -12) in 4 replicate blocks (R1-R4) for a total of 48 plots. From 2009-2018, plots were periodically fertilized following standard agronomic practices. In 2019, a 10 ft unfertilized subplot was established at the east end of each plot; the remaining 30 ft on the west end of the plot was fertilized at a rate of 56.0 kg N/ha/yr. The experiment was decommissioned in 2021 in favor of the Switchgrass Variety Experiment II.
