Plant CN content in T7

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Total carbon and nitrogen content on the T7 treatment. This table is a compilation of the harvested biomass (http://lter.kbs.msu.edu/datatables/40) and the CN Tissue Chemistry (http://lter.kbs.msu.edu/datatables/73).

This datatable is part of the Plant Carbon and Nitrogen Content dataset. This dataset includes total carbon and total nitrogen measured for plants from the LTER Main Site and the Successional and Forested sites. Total C and N are analyzed at peak biomass for a given treatment. In some systems with multiple harvests or complex communities that have peaks occurring at different times of the year, measurements are taken at multiple times per year. Samples are combusted and measured on a CHN analyzer.
