THE EFFECT OF WATER TABLE MANAGEMENT ON THE MIGRATION OF PHOSPHORUS AND ON GRAIN CORN IN SOUTHWESTERN QUÉBECPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 701P0304, .

In southwestern Qubec (Canada), annual precipitation generally exceeds evapotranspiration by
300 to 700 mm. Subsurface drainage is commonly used to improve the poor natural drainage
capacity of the regions agricultural fields, characterized by a flat topography and by the fact that
they are underlain by clay. Lowering the water table with artificial drainage has been shown to
improve crop growth. However, high pesticide and nutrient losses have sometimes been
attributed to subsurface drainage.
