Agronomic Soil Chemistry of Deep Cores — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic soil chemistry of deep core soil samples from all BCSE treatments (G1-G10) sent to a soil analytical laboratory for nutrient recommendations and analyzed by soil interval for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and organic matter. Note that soil intervals are composited by replicate (across sampling stations) for analysis.
This datatable is part of the Deep Core Soil Surveys–Biofuel Cropping System Experiment dataset.
Deep soil cores (to 1 m) are collected roughly every 5 years from all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BSCE) since its establishment in 2008. Soil cores are taken at all sampling stations (S1-S3) in each replicate (R1-R5), sectioned into 0-10, 10-25, 25-50, and 50-100 cm soil depth intervals, and each interval analyzed for bulk density, total carbon and nitrogen content, and agronomic soil chemistry. Soil texture and soil horizons were also identified in 2008.
