A Report on the Effects of Row Crops on Lake Ontario Watershed Health

Trent University’s Environmental and Life Sciences Graduate Program and School of the Environment completed a study, supported by Environment and Climate Change Canada and the Ganaraska Region Conservation Authority, to quantify changes in landuse/ landcover change within twelve Lake Ontario tributaries between 1971 and 2010, and to determine whether these changes co-occurred with changes in total phosphorus (TP) and nitrate nitrogen (NO3-N) concentrations. The study concluded that increases in row crop agriculture co-occurred with regional nutrient trends on a watershed scale.
