Kravchenko Lab

05/06/2022

Welcome James O'Sullivan a new postdoctoral researcher in the Kravchenko lab at Michigan State University. Using enzyme zymography, X-ray computed tomography and elemental mapping, James will unravel the mechanism of improved soil C storage under cover cropping. James recently completed his PhD where he examined how phosphorus acquisition and symbiotic N2 fixation is impacted by rising atmospheric CO2 concentrations.

Decomposing in-situ grown switchgrass roots as hotspots of microbial activity and N2O emission: the combination of dual-isotope labeling and zymography
https://meetingorganizer.copernicus.org/EGU21/EGU21-13272.html

▶Sasha Kravchenko
Whether enzyme activity is the same in different soil pores
https://meetingorganizer.copernicus.org/EGU21/EGU21-9009.html

▶Jinho Lee
Pore architecture and soil carbon accrual in soils under monoculture switchgrass vs. prairie soils
https://meetingorganizer.copernicus.org/EGU21/EGU21-14035.html

▶Maik Lukas
The effect of cover crops on soil structure is mainly driven by root architecture
https://meetingorganizer.copernicus.org/EGU21/EGU21-13448.html

An understanding of the drivers of hotspot/hot moments of N2O production is required to better constrain the global N2O budget and to plan the mitigation strategies. Hot spots are areas with very high N2O emission rates relative to the surrounding area, while hot moments are short periods of time wi...

Great news from Kravchenko Lab!
A study led by PhD candidate Alyssa Kim and Dr. Turgut Kutlu has been published in journal Plant and Soil with title “Dynamics of N2O in vicinity of plant residues: a microsensor approach”!

Link to publication 👉🏻 http://link.springer.com/article/10.1007/s11104-021-04871-7

We are planning to use microsensor techniques more actively, starting from taking the workshop from Unisense A/S in coming March.

Challenges with in situ visualizations of nonparticulate organics in porous materials limit understanding of organic compounds.
We tested a recently proposed method of staining soil organics by OsO4 vapors with subsequent dual-energy X-ray computed microtomography scanning (μCT). It offers new opportunities to visualize soil organic matter within an intact soil matrix. Please check the publication below!

The study was led by our visiting scholar Dr. Hongbing Zheng.

Congratulations to Alyssa Kim for receiving a Certificate in Computational Modeling from the College of Engineering! Alyssa also recently received the travel grant award from the Environmental Science and Policy program. She will use the funds to present her research at the European Geosciences Union, General Assembly, this May.
