Fulbright-Nehru Senior Distinguished Scholar – India, 2025
I had the honor of spending the first four months of 2025 as a Fulbright Scholar in India. I was hosted by Professor Nandula Raghuram at the Guru Gobind Singh Indraprastha University in New Delhi. Following upon collaborative work at Read More ...
Nitrogen 2.0: The Next Generation of Nitrogen Management in Food Production Systems
Davidson has joined Spark Climate Solutions, a philanthropically supported non-profit organization with a mission “to accelerate progress in under-addressed, high-impact climate mitigation and adaptation approaches”. He helped launch Spark’s Agricultural Nitrogen Transformation Program, which, as its name indicates, emphasizes the Read More ...
Global N2O Budget
Most of us know nitrous oxide as “laughing gas,” used for its anesthetic effects. But nitrous oxide (N2O) is the third most important long-lived greenhouse gas, after carbon dioxide (CO2) and methane. Nitrous oxide is also one of the main Read More ...
Science for a Green New Deal
The “Green New Deal” has been buried in the political shuffle in recent years, as its opponents have labeled it “woke” and erroneously characterized it as “socialism.” Nevertheless, the ideas of integrating climate science, economics, and social justice live on. Read More ...
Avoiding Pollution Swapping while Reducing Agricultural Runoff of Nitrogen to the Chesapeake Bay
Faculty, staff, and students from the Appalachian Laboratory, the Horn Point Laboratory, and Washington College and a local farmer were featured on a Maryland Public Television segment on Maryland Farm and Harvest, describing their on-farm research on the Delmarva Peninsula. Their research shows that the water level Read More ...
Integrated Belowground Greenhouse Gas Flux Measurements and Modeling
Our main objective is to improve understanding of and modeling capacity for interactions of belowground temperature, moisture, and substrate supply that controls the net soil emissions of the three most important anthropogenic GHGs: CO2, CH4, and N2O. We have developed a novel integration of measurement and Read More ...
Dr. Davidson and his team’s research in biogeochemistry includes the exchange of plant nutrients from the land to streams and groundwater and the exchange of greenhouse gases between the soil and the atmosphere.
Areas of expertise include:
- Biogeochemical effects of land-use change and land management
- The global nitrogen cycle, including the global nitrous oxide budget
- Soil microbial processes of nutrient cycling and greenhouse gas fluxes
- Leaching of plant nutrients to streams and groundwater
- Interdisciplinary studies of nitrogen management in agriculture
- Interactions of C, N, P, and other nutrient cycles in terrestrial ecosystems
- Land-water-atmosphere exchanges of greenhouse gases and nutrients
- Temperature sensitivity of soil organic matter decomposition
- Modeling soil microbial processes
