Soil Leachate via Suction Lysimeters - Inorganic Nitrogen — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Inorganic nitrogen in soil leachate collected from the Main Cropping System Experiment using suction lysimeters.
This datatable is part of the Nitrogen in Soil Water Chemistry on the Main Cropping System Experiment dataset.
Soil water samples are collected every other week during the growing season from mainsite 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 sometimes are grouped. In this dataset nitrate and ammonium were analyzed. See also the dataset entitled Comprehensive Soil Water Chemistry on the Main Cropping System Experiment which covers a larger set of chemical variables from 1999-2003. Total dissolved nitrogen (TDN)and dissolved organic nitrogen (DON) measurements were also made on on the soil water samplers in 1995 & 1996- database manager for TDN and DON data.
