Soil Texture and Soil Organic Matter at ERT Plots — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 texture and soil organic matter data collected at ERT (electrical resistivity tomography) plots.
This datatable is part of the Soil moisture determinations by Electrical Resistivity (ERT) Experiment dataset.
Large-scale conversion of croplands to perennial biofuel crops could substantially impact regional water, nutrient, and C cycles due to the longer growing seasons and differences in rooting systems compared with most annual crops. However, these differences in crop water use are not well known due to the limited tools available to nondestructively study the spatiotemporal patterns of root water uptake in situ at field scales. Geophysical imaging tools such as electrical resistivity (ER) reveal changes in water content in the soil profile.
