GLBRC Sustainability Data Catalog

MLE rainfall manipulation experiment soil moisture (automated)

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

GLBRC soil water content under rainout shelters in adjacent areas. This dataset is used to confirm that the rainout shelters are producing enough of a drought to stress the switchgrass

This datatable is part of the MLE – Rainfall Exclusion Experiment dataset. This dataset contains data from Rainfall Exclusion Experiment at Marginal Land Sites. The purpose of the experiment is to learn the drought effects on switchgrass. Data in this dataset can also be found in the dataset of Marginal Land Experiment.
