Impact of agricultural practices on water quality

Several research investigations have been initiated in Nova Scotia through private-public partnerships to examine the impact of agricultural activitie s on surface and groundwater quality. These include 1) the evaluation of ar tificial (constructed) wetlands for the treatment of milkhouse waste water and manure runoff from agricultural systems under cold climate conditions, 2) the impact on subsurface drainage water quality of different rates and t iming of manure application, 3) the impact of two carrot fertility manageme nt systems (liquid hog manure and chemical fertilizer) on subsurface draina ge water quality, 4) subsurface drainage water quality under composted and fresh chicken manure as a soil amendment, 5) evaluation of alternative milk house wastewater treatment methods, and 6) the occurrence of Hexazinone in domestic wells adjacent to wild blueberry fields.
