My research focuses on the effects of the freeze-thaw cycles on carbon, nitrogen and phosphorus speciation dynamics across the reactive interfaces in agroecosystems. Currently, the ongoing displacement of climate zones by global warming is altering the frequency and intensity of freeze-thaw cycles experienced by soils, increasing its impact on soil physical, hydraulic and chemical properties. These effects are particularly important to agriculture soils as they relate to nutrient availability. The presence of nutrients in soil is imperative to crop growth where any changes in soil nutrient availability can affect the viability of crops in a world challenged by food security. My research helps us to understand how freezing and thawing influences the leaching of nutrients from subsoils to groundwater, and how future climate change may impact water quality in agricultural landscapes.
