These soybeans were no-tilled into corn stubble. Benefits of no-till include reducing erosion, increasing soil quality and organic matter, reducing energy use and increasing plant-available moisture.

This aerially-applied cover crop mix consists of oats, cereal rye, turnip, hairy vetch and rape. Benefits of cover crops include reducing soil erosion, increasing soil quality and organic matter, limiting nitrogen leaching and suppressing weeds.

A cereal rye cover crop provides excellent cover for wildlife.

This field has been part of a no-till system for more than 15 years.

Central Turkey River Nutrient Reduction Demonstration Project

This project is funded by the Iowa Department of Agriculture and Land Stewardship's (IDALS) Water Quality Initiative. Statewide, there are 57 demonstration projects (23 farm and 34 urban) which all focus on the adoption of the Iowa Nutrient Reduction Strategy (NRS). The Iowa NRS is a science and technology-based approach to assess and reduce nutrients delivered to Iowa waters and the Gulf of Mexico. The strategy outlines voluntary efforts to reduce nutrients in surface water from both point sources, such as wastewater treatment plants and industrial facilities, and nonpoint sources, including farm fields and urban area, in a scientific, reasonable and cost effective manner. The final version of the Iowa NRS was released in May 2013.

This project began in 2014 and has been extended through 2019. The project area encompasses roughly 75,000 acres in southwestern Winneshiek County, with some acres in Chickasaw and Fayette Counties as well. The Burr Oak, Brockamp, Rogers and Wonder Creek Watersheds are included in the project. Project partners include IDALS and Clean Water Iowa, United States Department of Agriculture-Natural Resources Conservation Service, Northeast Iowa Community College and Northeast Iowa Community-Based Dairy Foundation, Farmers Union Cooperative, Fayette SWCD, Winneshiek County Conservation, Iowa State University Extension and Outreach, Iowa Department of Natural Resources and Turkey River Watershed Management Authority.

Cost-share is available for the following practices. Producers interested in these practices are encouraged to apply early due to conservation planning requirements and limited funds available.
