Soil Leachate via Suction Lysimeters - Major Ions — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Water chemistry of soil leachate collected from the Main System Cropping Experiment using suction lysimeters.
This datatable is part of the Comprehensive Soil Water Chemistry dataset.
Soil water samples are collected every other week during the growing season from treatments 1-7 (replicates 2-4) and the successional and forest sites using Prenart soil water samplers (sometimes referred to as lysimeters). Three sampling stations are located in each treatment and are grouped in this analysis. In this dataset, the following chemical variables were measured from 1999-2005: Ca, Mg, Na, K, NO3, total alkalinity, Cl, SO4, NH4,PO4, DOC, specific conductance, total dissolved phosphorus and Si. See also the dataset entitled Soil Water Nitrate on the Main Cropping System Experiment which covers a longer time period.
