Sustainable agriculture depends on the promotion and management of healthy soils. Healthy soils support root growth and beneficial microbes, such as mycorrhizal fungi, to enhance soil quality, nutrient uptake and crop production. A student working on this project will investigate root and fungal interactions and how they relate to root and soil health.
Forests can be major sinks for carbon in a changing climate. One of the greatest uncertainties in terrestrial carbon fluxes is that occurring belowground. A student on this project will work on questions of how does soil moisture and nutrients affect root production and turnover and soil CO2 in a changing climate.
