Kate Congreves

Dr. Congreves’ research program is focused on understanding nitrogen (N) flows, cycling, and losses in crop production systems. She studies the fundamental mechanisms that regulate N cycling ecosystem processes in a range of cropping systems, including field crops, specialty crops, and horticultural crops. Her lab specializes in field-based agronomy research, using 15N stable isotopes techniques to trace N dynamics, and measuring greenhouse gas emissions via flux gradient micrometeorological techniques and with chambers. Current projects are addressing how diversification of cropping systems can control soil N transformations and supply, crop N uptake and use efficiency, and N2O emission dynamics. The long-term vision is widespread implementation of sustainable N management, and the creation of regenerative agroecosystems that do not pose reactive-N threats to our environment.
