crop agriculture in Indiana - Agricultural nutrient losses
contribute to hypoxia in the Gulf of Mexico and eutrophication
in the Great Lakes. Our objective was to assess effects of
topography, geomorphology, climate, cropping systems and land
use and conservation practices on hydrology and nutrient fate
and transport in the St. Joseph River watershed. We monitored
five sites (298 to 4,300 ha [736 to 10,600 ac]) on two drainage
ditches within the St. Joseph River watershed in northeastern
Indiana. Row crop agriculture, primarily corn (Zea mays L.) and
soybean (Glycine max [L.] Merr.), is the dominant land use
(approximately 60%) in this pothole or closed depression
landscape. The hydrology is dominated by subsurface tile
drainage supplemented with surface drainage of remote potholes.
Vegetative buffer strips have been implemented along >60% of the
agricultural drainage ditches. The vegeta
