GLBRC Scale-up Soil Properties

GLBRC124:GLBRC Scale-up Soil Properties

Soil properties of fields at Lux Arbor Reserve (L1-L3) and Marshall Farm (M1-M4) planted to corn (L1, M1), switchgrass (L2, M3), and restored prairie (L3, M2) in 2010 after a 2009 no-till soybean crop in all fields to convert tilled corn-soybean-wheat rotations (AGR) at Lux Arbor and fields in the Conservation Reserve Program (CRP) at Marshall Farm to no-till bioenergy crops. One field at Marshall Farm (M4) remained as CRP brome grass to serve as a reference. Each field has 10 sampling stations (S1-S10) around which most soil sampling occurs.


GLBRC088-006 Soil Bulk Density

Soil bulk density of surface and deep core samples taken from fields of the GLBRC Scale-up Experiment.

GLBRC088-007 Soil Total Carbon and Nitrogen

Total carbon and nitrogen content of surface and deep core samples from fields of the GLBRC Scale-up Experiment. A dried subsample is ground and analyzed for carbon and nitrogen content, reported as a percentage.

GLBRC088-009 Agronomic Soil Chemistry

Soil samples are taken on a near annual basis (usually after harvest in the fall) for fertilizer recommendations and analysis of pH, lime index, phosphorus, potassium, calcium, magnesium, and cation exchange capacity by an analytical service lab (Michigan State University Soil and Plant Nutrient Laboratory through 2022). Ten surface cores (0-25 cm) are collected at each sampling station, composited by station, then sieved and air dried before sending out for analysis. Note that these samples may also be analyzed for soil moisture and inorganic N.

GLBRC088-014 Soil Inorganic Nitrogen

Soil extractable nitrogen (ammonium and nitrate plus nitrite) concentrations, corrected for soil moisture, in surface soils of the GLBRC Scale-up Experiment, reported as mg N per kg dry soil.

GLBRC088-017 Soil Texture of Deep Cores

Soil texture (percentage sand, silt, and clay) of deep core samples from fields of the GLBRC Scale-up Experiment. Deep core samples are divided into four depth intervals (0-10, 10-25, 25-50, and 50-100 cm).

GLBRC088-020 Soil Moisture (Gravimetric)

Gravimetric soil moisture of surface cores from fields of the GLBRC Scale-up Experiment. These data are used to adjust the soil inorganic nitrogen measurements for moisture.

GLBRC088-022 Soil pH

Soil pH of surface cores (0-25 cm) from fields of the GLBRC Scale-up Experiment taken periodically in the fall to monitor the need for soil liming.

GLBRC124-001 Delta T Soil Moisture

Soil moisture measurements were made with a Delta T soil moisture probe at multiple sample stations in fields at Marshall Farm in 2016.
