Description

With the release of the Iowa Nutrient Reduction Strategy in early 2013 there has been increased interest in what practices can be utilized by farmers to reduce nutrient export to downstream water bodies. As highlighted by the ISU Extension and Outreach Special Publication 235 (2013) there are many in-field, land use, and edge-of-field practices that have potential to reduce nutrient export. Three practices that have garnered a substantial amount of interest are cover crops, bioreactors, and wetlands. These three practices span the scale from in-field (cover crops) to edge-of-field (bioreactors) to watershed scale (wetlands).
