Anion samples from the Porewater samplers on the north end of the MCSE plots — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Rain exclusion experiment subplots were set up on the north end of T1 and T2 MCSE plots in 2015, allowing for plot manipulation with 5m x 5m Rainout shelters and porewater samplers installed in the centers of each subplot at 120cm depth. After the bromide tracer was applied, leachate collection and analysis were used to show rates of percolation based on tillage and rainfall manipulation (or lack thereof). Shelters were removed in 2018, but the samplers remain in place.
