Soil moisture profiles in replicate 1 of the BCSE — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Soil moisture is measured with Campbell CS650 soil moisture probes (https://www.campbellsci.com/cs650) in Replicate 1 of the BCSE. The Soil moisture probes were installed vertically at 3 depth: 0, 30 and 60 centimeters. The probes are slighly offset to avoid disturbance from the upper probe affecting the lower one.
This datatable is part of the Profile Soil Moistures dataset. Soil moisture profiles were meaured at the BCSE with several techniques. Initially we installed a TDR array at 7 depths. In 2019 we installed a set of campbell CS650 probes at 3 depth in a subset of the plots.
