Project type

Large-Scale EMSL Research

The association of organic nitrogen (N) compounds with soil minerals is an important mechanism for determining the long-term persistence of N in soils and N bioavailability. Mounting evidence points…

Absolute quantification of components of the algal photosynthetic apparatus in response to environment and modification of chlorophyll biosynthesis

Lead Institution

University of California, Berkeley

Principal Investigator

Sabeeha Merchant

Project type

Large-Scale EMSL Research

The operation of the photosynthetic apparatus is influenced by environment, particularly stress situations like poor iron nutrition, carbon or light limitation, and excess excitation energy, which…

Project type

Large-Scale EMSL Research

This project develops a physics-informed machine learning (PIML) methodology to upscale soil structural information (e.g., X-ray and microscopy images) to continuum-scale process models (e.g., DOE…

Baggs MONet Request: The effects of agricultural nitrogen fertilization regimes on soil geochemistry

Lead Institution

Sound Agriculture

Principal Investigator

Erin Baggs

Project type

MONet

Agriculture impacts the environment through several biogeochemical cycles that are relevant at local to global scales. To efficiently obtain high yielding harvests farmers are required to use…

Ward Jones MONet Request

Lead Institution

University of Alaska Fairbanks

Principal Investigator

Melissa Ward Jones

Project type

MONet

Climate warming is benefitting high latitude agriculture by increasing air temperatures and the growing season length. However, permafrost (perennially frozen ground) thaw is accelerating and causing…

Becklin MONet Request

Lead Institution

Syracuse University

Principal Investigator

Katie Becklin

Project type

MONet

Climate change is altering the timing of important developmental events, such as when plants emerge, flower, and senesce during the growing season. These phenological events determine the timing of…

PI Goemann MONet Request

Lead Institution

Montana State University

Principal Investigator

Hannah Goemann

Project type

MONet

Just as humans rely on a healthy gut microbiome for resilience to illness, plants rely on a healthy root microbiome for resilience to environmental abiotic stress (heat, drought). To achieve a…

Ricketts MONet Request

Lead Institution

Argonne National Laboratory

Principal Investigator

Michael Ricketts

Project type

MONet

Switchgrass is a potential bioenergy feedstock and has adapted to a wide range of environments by exhibiting a variety of trait combinations that has resulted in multiple ecotypes across its range…

Characterization of soil functions following forest conversion

Lead Institution

United States Department of Agriculture - Forest Service

Principal Investigator

Carl Trettin

Project type

MONet

The objective of this proposal is to characterize changes in soil functions associated conversion of the forest cover type from loblolly pine (Pinus taeda) to longleaf pine (Pinus palustris). This…

Soil mineralogy control on SOC stability in soils

Lead Institution

United States Department of Agriculture - Agricultural Research Service

Principal Investigator

Zamir Libohova

Project type

MONet

Soil Organic Carbon (SOC) pools and stability are influenced by interactions between climate, management, and soil properties. Numerous studies have determined the size and stability of SOC pools by…

Grazing Impacts on Soil Organic Carbon Chemistry and Microbial Community Structure and Functions in a Mixed-Grass Ecosystem

Lead Institution

University of Wyoming

Principal Investigator

Mengqiang Zhu

Project type

MONet

Grasslands cover approximately 40% of the Earth's land surface and represent about 70% of the agricultural area. They contain about 10% of terrestrial biomass and contribute about 20–30% of the…

Waldbauer MONet Request

Lead Institution

University of Chicago

Principal Investigator

Jacob Waldbauer

Project type

MONet

The Arctic is warming twice as fast as the rest of the planet, and Arctic soils currently store twice as much carbon as the entire atmosphere. These two facts make understanding how Arctic soil…
