Leopold Center for Sustainable Agriculture

Completed Grants

This is where you will find all of our grant reports. The Leopold Center has operated a competitive grants program since 1988, funding more than 420 Iowa-based projects in every county in Iowa.

The most recently completed projects are listed first. Click on the title to see the abstract, key findings and links to printable summaries of findings from each project. For more details about a project than what is included in the project summary documents, contact the lead investigator (email address is in the longer project summary).
