GLBRC soil properties

GLBRC088:GLBRC soil properties

Soil measurements from GLBRC experiments.


GLBRC088-001 Soil pH
Soil pH from the surface soils of the GLBRC Intensive Sites.
GLBRC088-002 Soil Moisture
Soil moisture measurements from the GLBRC Biofuel Cropping System Experiment.
GLBRC088-003 Soil Bulk Density - GLBRC Intensive Sites
Soil bulk density data from the GLBRC Biofuel Cropping System Experiments at Kellogg Biological Station and Arlington ; data include the deep core samples (collected every 5 years) and surface soil samples.
GLBRC088-005 Arlington Baseline Surface Soil Survey
Soil analyses collected 30 June-2 July 2008, serve as a baseline soil survey for the Arlington GLBRC Intensive Site. - Only 1 bulk density core was taken per plot. This value is applied to all subsamples in the plot. - All are from horizon "act". The 0-10 cm samples were collected with 6 cm height cores and the 10-25cm samples were collected with 15 cm height cores. - Core diameter for all - 3.7 cm.
GLBRC088-006 Soil Bulk Density - GLBRC Scale-up sites
Bulk density measured on the GLBRC scale-up sites. FieldID: M1=Marshall corn, M2=Marshall prairie, M3=Marshall switchgrass, L1=Lux Arbor corn, L2=Lux Arbor switchgrass, L3=Lux Arbor prairie
GLBRC088-007 Soil Carbon and Nitrogen Content- GLBRC Scale-up sites
Surface soil carbon and nitrogen data from soil samples taken at each station on the GLBRC Scale-up fields.
GLBRC088-008 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 and University of Wisconsin Soils Laboratory .
GLBRC088-011 Soil Inorganic Nitrogen- Switchgrass Nitrogen/Harvest Experiment
Soil extractable nitrogen from the Switchgrass Nitrogen/Harvest Experiment.
GLBRC088-012 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.
GLBRC088-013 Soil Inorganic Nitrogen- Resin Strip Method
Soil nitrate and ammonium data determined using the resin strip method. This method was only used in 2009. See Related Tables below for additional inorganic N data.
GLBRC088-016 Soil Texture- Deep Core - GLBRC Intensive Site
Soil texture from the GLBRC intensive site. Soil core was collected with the deep core sampler.
GLBRC088-017 Soil Texture - Deep Core - GLBRC Scale-up sites
Soil texture (sand, clay and silt) from the GLBRC Scale-up sites.
GLBRC088-018 Soil Temperature
Soil temperature measurements from the Arlington GLBRC Biofuel Cropping System Experiment. KBS does not measure temperature when soil sampling.
GLBRC088-019 Nitrogen mineralization
During 2013, nitrogen mineralization and nitrification rates were measured at the GLBRC Intensive sites. Each main plot and microplot was measured 3 times (early growing season, mid-growing season, and post-harvest) using 28-day lab incubations at constant soil moisture and temperature. This table contains the change in soil nitrate (plus nitrite) and ammonium over the incubation period, which is used to calculate potential mineralization and nitrification rates.
GLBRC088-020 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.
GLBRC088-021 Soil Carbon and Nitrogen- Baseline Prior to GLBRC Intensive Site
One hundred soil samples were collected prior to setting up the GLBRC Biofuel Cropping System Experiment on the KBS GLBRC Intensive site. Samples were taken on a regular grid (20 x 100 meters) and sample coordinate locations were recorded with GPS. The sample grid included the area that soon after became the the GLBRC Biofuel Cropping System Experiment and Switchgrass Nitrogen/Harvest Experiment.
GLBRC088-022 Soil pH - GLBRC Scaleup sites
Soil pH from the GLBRC scaleup fields.
GLBRC088_023 Soil Texture and Soil Organic Matter at ERT Plots
Soil texture and soil organic matter data collected at ERT (electrical resistivity tomography) plots.
GLBRC088-023 Field Moist Soil pH
Field moist soil pH from the Switchgrass N gradient taken to evaluate the need for liming.
