Volumetric Soil Moisture -- with Trace Gas Sampling — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Volumetric soil moisture measurements were taken along with the static trace gas sampling campaign. A Hydrosense probe with the 12 cm probe head was used to measure the soil moisture on the same day as the gas sample. Measurements below 6% soil moisture are set to 6% since that is the detection limit of the Hydrosense probe.
This datatable is part of the Trace Gas Fluxes on the Main Cropping System Experiment dataset.
Trace gases (nitrous oxide, methane, and carbon dioxide) have been measured on the LTER Main Site since 1991 and on Successional and Forest sites since 1993. Trace gas fluxes are measured twice monthly or monthly until the ground freezes using permanently-installed, in-situ static chambers. CH4 and N2O are analyzed with gas-chromatography and CO2 with an infrared gas analyzer. Soil moisture and temperature are measured during sampling.
