Investigating mechanisms for negative priming of soil organic carbon by pyrogenic carbon using NanoSIMS and LA-AMS

Lead Institution

Cornell University

Principal Investigator

Johannes Lehmann

Project type

Large-Scale EMSL Research

Reduced turnover rate (often referred to as “negative priming”) of soil organic carbon (SOC) by pyrogenic black carbon (pyC) has the potential to have dramatic long-term effects on soil carbon stocks…

The effect of C decomposition environment on plant detritus in soil organic matter

Lead Institution

University of Wisconsin, Madison

Principal Investigator

Randy Jackson

Project type

Exploratory Research

While it is established that increasing temperature and moisture increases the rate of soil C mineralization, we do not know whether these factors change the chemical quality or physical protection…

Investigating interactions between soil microbial communities and soil organic matter dynamics along climate and vegetation gradients

Lead Institution

Michigan State University

Principal Investigator

Jessica Miesel

Project type

FICUS Research

Soils hold globally-important stocks of organic matter, with critical relevance for nutrient cycling and climate change. As the primary agents of decomposition, soil microbes play a key role in soil…
