Snowfall timing and duration is predicted to change over approximately 58% of the northern hemisphere. We are interested in how snow cover affects freeze-thaw cycling, and how the freeze-thaw cycling influences soil biophysical (soil detachment) and soil biogeochemical (nutrient migration) cycles.
Soil Aggregate Stability and Freeze Thaw Cycles
This research focuses on snow cover changes, freeze-thaw cycles, soil organic carbon and aggregate dynamics, and soil erosion.
Nutrient Dynamics and Soil Freeze Thaw Cycles
This project focuses on understanding thermal diffusion and matric potential induced soil nutrient (nitrogen and phosphorus) movement as a result of freeze-thaw cycles in agricultural fields.
SOIL MATRIX TEMPERATURE GRADIENT INFLUENCE ON MIGRATION OF PLANT NUTRIENTS IN SOIL
We are collaborating with researchers in India and Alaska to understand the influence of non-isothermal temperature gradients on soil nutrients migration in different climates.
