Reducing phosphorus runoff

Reducing phosphorus runoff

Is it possible to reduce the amount of phosphorus being released from agricultural land and into waterways, such as Lake Winnipeg, during the spring melt? It’s a question UWinnipeg Professor Dr. Darshani Kumaragamage, Department of Environmental Studies and Sciences, and her research team are trying to answer. In most parts of the world, erosion, and rain-driven runoff are the major pathways by which phosphorus from agricultural fields enter waterbodies. However, in cold climates like the Canadian prairies, flooding-induced phosphorus loss during the snowmelt period is the dominant transport mechanism of phosphorus from agricultural lands to water bodies.
