Agronomic Soil Chemistry — GLBRC Biofuel Cropping System Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Surface soil samples (0-25 cm) are collected annually (usually in the Fall) from the main plot and alternative treatment subplots (most years) of all BCSE treatments (G1-G10), then dried and sent to an analytical laboratory for fertilizer recommendations and analysis of pH, lime index, phosphorus, potassium, calcium, magnesium, and cation exchange capacity. Beginning in 2018, samples from annual treatments are analyzed every year and those from perennial crops are analyzed every three years.
This datatable is part of the GLBRC Soil Properties — Biofuel Cropping System Experiment dataset.
This dataset contains the chemical and physical properties of surface (0-25 cm) and deep (0-1 m) core soils of the GLBRC Biofuel Cropping System Experiment (BCSE).
