I primarily work as an agroecosystem model developer on the farm GHG model DNDCv.CAN. The DNDC model is farm field and facility model that is used to estimate carbon, nutrient, water and trace gas dynamics at the field/farm scale. An extensive knowledge of agronomy and soil processes, along with a collaborative partnership with other measurement researchers helps to ensure the model can effectively replicate the complex interdependent processes that are present in agroecosystems. It is one of a few models worldwide that can assess complex integrated management such as 4R and cover cropping impacts.
Using this tool, I work to investigate ag-management impacts on crop productivity and environmental sustainability as well as the long-term impacts of climate change on cropping system resilience.
The farm facility branch of the DNDC model (Manure-DNDC) is useful for the investigation of nutrient and water dynamics of full-farm livestock waste management systems.
Much of our work is focused on international partnerships between other institutions and through AgMIP and GRA initiatives to enhance and incorporate the current understanding of crop-soil-atmospheric processes into modeling frameworks.
The overall aim is to help develop and integrate new approaches into AAFC activities to help Canada meet it's international commitments towards reducing GHG emissions from agriculture and ensuring producers future market competitiveness
20+ years focused on the application and development of process-based agroecosystem models. DNDC, Century, DayCent, Campbell, Epic, RZWQM2.
