Leopold Center for Sustainable Agriculture

Organic production practices and comparisons

Long-Term Agroecological Research

The Long-Term Agroecological Research (LTAR) experiment at the ISU Neely-Kinyon Research and Demonstration Farm near Greenfield, Iowa, was set up in 1998, the capstone of the Organic Ag program at Iowa State University. It is one of the longest running comparisons of organic and conventional crops in the country.

Organic Agriculture

The Leopold Center has been able to significantly add to the body of knowledge about organic agriculture over the past two decades, even though less than 10 percent of the Center's research dollars goes to studying organic systems.
