Nutrient pollution originating from agricultural regions in the Midwest is a serious issue, leading to pollution of drinking water sources as well as large hypoxic zones in the Gulf of Mexico. The source of much of this contamination has been shown to be runoff from agricultural fields in the Upper Mississippi River Basin. One method that has been shown to reduce this pollution from the Upper Mississippi River Basin is the planting of winter cover crops. Winter cover crops such as rye and tillage radish have been shown to significantly reduce nitrate exported from agricultural fields, even in tile-drained watersheds …

Communities of soil-dwelling organisms contribute to soil fertility and nutrient cycling, but conventional farming practices can disturb and reduce these communities. In southeastern Minnesota, some farmers are planting simplified prairie vegetation to produce biomass fuels. Our study was designed to assess the species abundance and diversity of soil invertebrates in plantings of mixed grasses only (MG) and mixed grasses with forbs (MGF) that were planted for use as a biomass fuel source on a farm in southeastern Minnesota in 2007. Abundance and diversity of soil invertebrates also were examined in soils of corn (Zea mays L.) fields grown on the …
