Soil organic matter dynamics: a cross-ecosystem approach – support for a cross-LTER workshop
LTER Network Office,
Co-Principal Investigator (PI: Kate Lajtha, Oregon State University)
Organized a 2-day meeting in 2010 bring together scientists from several LTER sites interested in comparative SOM analysis. Our goal was to discuss the various tools and techniques that could and should be used in experimental SOM studies as well as to plan additional cross-site comparisons. The goal was to have scientists conducting quite different experiments, such as N fertilization studies, harvest or biodiversity studies, alien plant invasion measurements, or even DIRT studies, but who all wanted to examine soil organic matter as a response variable, could agree on some standard analytical techniques so that data set could be used in synthetic studies. We also wanted a time when the PIs of the different DIRT experiments could meet for a few hours to plan joint publication of existing data as well as to standardize other measurements to allow for future comparative analysis and publication. Thus participants included faculty and students involved in the Harvard Forest chronic N analysis, all the DIRT site lead scientists, an emerging scientist studying shrub invasions in grasslands, and forest clearing experiments.
