Chatting about Cover Crops in Iowa with Dr. Tom Kaspar

In Episode 6 of the Iowa Learning Farms “Conservation Chat” Jacqueline Comito talks cover crops with Dr. Tom Kaspar.  Tom is a plant physiologist at the USDA-ARS National Laboratory for Agriculture and the Environment in Ames.


Tom Kaspar digs up some of the cover crop roots in his long-term research plots.

With 25+ years of cover crop experience, Tom is considered the one of the foremost experts on cover crops in Iowa and serves as member of the Midwest Cover Crops Council and the Iowa Cover Crop Working Group.

Tom began his career in the 1980s researching no-till and other minimum tillage practices as methods for reducing soil erosion.  Around 1989, he began to wonder – what will be the next addition for no-till to further protect the soil from erosion?  The answer he turned to—cover crops!
