Principal Investigator

Sarah Leichty

Soil organic matter (SOM) provides ecosystem services such as soil fertility and climate mitigation, holding the key to agricultural sustainability in a rapidly changing world. Despite the important…

The Influence of Crop Selection and Soil Properties on the Accumulation and Stabilization of Microbial Residues in Soil

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Kirsten Hofmockel

EMSL Staff Proposal: The proposed research confronts the emerging paradigm that dead microbial cells, or necromass, are a major source of organic carbon in soil. Microbial necromass accumulation may…

Elucidating unifying principles of soil C-N coupling using a continental scale grassland experimental network

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Kirsten Hofmockel

EMSL capabilities will be utilized for analysis of samples acquired from a continental-scale network of replicated, long-term grassland nutrient addition experiments, the Nutrient Network, to enhance…

Feedbacks between microbial community dynamics and the persistence of soil organic carbon

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Kirsten Hofmockel

Project type

Exploratory Research

Soil organic matter (SOM) is the largest active carbon reservoir in the terrestrial environment and significantly influences soil fertility, water quality, global C cycling and associated feedbacks…

Controls on the Composition of Persistent Microbial-derived Organic Matter in Soil

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Kirsten Hofmockel

Project type

Exploratory Research

Current estimates suggest that soils contain 1.5 x 10^12 tons of carbon, or roughly three times more carbon than the atmosphere, and represent a giant reservoir for potential greenhouse gas emission…

Tracing rhizosphere carbon exchange processes and nutrient interactions

Lead Institution

Michigan State University

Principal Investigator

James Moran

Rhizodeposition represents the largest flux of photosynthetically derived organic matter into soil for most terrestrial systems and, in so doing, serves as a major point of connection between…
