RESEARCH INTERESTS

Dr. Dijkstra studies effects of global climate change on soil processes such as organic matter decomposition, nutrient cycling, and exchange of greenhouse gasses in semi-arid grasslands. Currently he is involved in the Prairie Heating And CO2 Enrichment (PHACE) experiment studying the effects of elevated CO2 and warming on carbon and nutrient cycling.
