Tables

KBS078-001 Soil pH
Soil pH from the surface soils of the GLBRC Intensive Sites.
KBS078-002 Soil Moisture - Gravimetric
Soil moisture measurements from the GLBRC Intensive site.
KBS078-003 Soil Bulk Density - Surface and Deep Cores
Soil bulk density of surface and deep core soil samples from the GLBRC Biofuel Intensive site.
KBS078-005 Soil Bulk Density - Surface and Deep Cores
Soil bulk density on surface and deep core soil samples from the GLBRC Biofuel Scale-up sites.
KBS078-006 Soil Inorganic Nitrogen
Soil extractable nitrogen from soils of the Switchgrass Nitrogen/Harvest Experiment at the GLBRC Biofuel Intensive site. Plants are grown under 8 treatments of nitrogen fertilizer and two harvest strategies.
KBS078-007 Soil Inorganic Nitrogen
Soil extractable nitrogen from the GLBRC Biofuel Cropping System Experiment. Soil nitrate and ammonium are sampled routinely during the growing season. Note that in 2009 inorganic N was determined using the resin strip method; see related tables below.
KBS078-008 Soil Inorganic Nitrogen via Resin Strips
Soil nitrate and ammonium data for the GLRBC Biofuel Intensive site determined using the resin strip method. This method was only used in 2009. See Related Tables below for additional inorganic N data.
KBS078-009 Soil Total Carbon and Nitrogen - Surface and Deep Core
Carbon and nitrogen measurements of surface soil samples taken from each station on the GLBRC Biofuel Scale-up sites.
KBS078-010 Soil Inorganic Nitrogen
Soil extractable nitrogen from the GLBRC Biofuel Scale-up Experiment.
KBS078-011 Soil Moisture via TDR - Daily
Automatically cleaned daily median volumetic soil moisture from the TDR array on the GLBRC Biofuel Intensive site. The hourly data is passed through a 13 point median filter, then the daily median is retrieved and the result is passed through a 3 point filter that passes the middle point if the vwc is within 0.03 % of the mean of the surrounding points if it did not rain in the last 2 days. If it did rain it middle point is accepted if it is higher than the mean of the outside points. There are still some points that should be deleted.
KBS078-012 Agronomic Soil Chemistry - GLBRC Intensive Sites
Soil samples are taken annually (usually in the Fall) for fertilizer recommendations and analyzed for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and organic matter. KBS samples are analyzed by the Michigan State University Soil and Plant Nutrient Laboratory .
KBS078-013 Soil Texture by Depth - Deep Cores
Soil texture from the GLBRC Intensive site.
KBS078-014 Soil Texture by Depth - Deep Cores
Soil texture of deep core soil samples from the GLBRC Biofuel Scale-up sites.
KBS078-015 Agronomic Soil Chemistry - KBS GLBRC Scaleup sites
Soil samples are taken annually (usually in the Fall) for fertilizer recommendations and analyzed for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and organic matter. KBS samples are analyzed by the Michigan State University Soil and Plant Nutrient Laboratory .
KBS078-016 Soil Moisture GLBRC Scale-up
Gravimetric soil moisture at the GLBRC Scale-up sites. This data is used to adjust the inorganic soil nitrogen data for moisture.
KBS078-017 Carbon and Nitrogen- Baseline Prior to GLBRC Intensive Site
KBS078-018 Soil pH - GLBRC Scaleup sites
Soil pH from the GLBRC scaleup fields.
KBS078-019 Soil Texture and Soil Organic Matter at ERT Plots
Soil texture and soil organic matter data collected at ERT (electrical resistivity tomography) plots.
KBS078-020 Field Moist Soil pH
Field moist soil pH from the Switchgrass N gradient taken to evaluate the need for liming.
