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
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.
GLBRC088-008 Agronomic Soil Chemistry
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 .
GLBRC088-012 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
Soil texture from the GLBRC BCSE (Biofuel Cropping System Experiment) site. Soil core was collected with the deep core sampler.
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.
GLBRC088-021 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_023 Soil Texture and Soil Organic Matter at ERT Plots
Soil texture and soil organic matter data collected at ERT (electrical resistivity tomography) plots.
GLBRC088-024 Gravimetric soil moisture for BCSE rainout shelter experiment
Gravimetric soil moisture of rainout shelter experiment at the GLBRC BCSE.
