Dr. Naughton’s group studies how soil chemical and physical attributes affect microbial activity, particularly the turnover of key nutrients like carbon and nitrogen. Soil varies in key qualities such as nutrition or moisture over very short spatial scales, like within a forest stand or agricultural plot. Our group studies the extent of this variation, how it changes the environmental living conditions experienced by soil microbes, and how microorganisms respond through their community composition and metabolisms. This work relates to terrestrial nutrient cycles, (greenhouse) gas fluxes from soils, and healthy soils and ecosystems.
Our current research foci include:
- Forest disturbance effects on carbon inputs to and gas emissions from soils
- Soil health outcomes from drought-tolerant dual purpose summer cover crops
- Drivers of anoxic microsites within upland soils, and impact on predicting soil gas fluxes
Courses taught:
- Agricultural Chemistry (STOCKSCH 117)
- Introduction to Soil Science (STOCKSCH 105)
