AgEmerge Podcast 128 with Don Reicosky

Dr. Don Reicosk. Dr. Reicosky is a retired Soil Scientist for the USDA-ARS, North Central Soil Conservation Research Laboratory, Morris, MN, and Adjunct Professor in the Soil Science Department, University of Minnesota, St. Paul. He has an exciting discussion with Monte about the foundational research he conducted back in the late 1990’s finding that tillage releases carbon into the atmosphere in sudden rushes of CO2 as soil is opened up. And now, more than ever, Dr. Reicosky uses his time to help growers know this critical information, whether it's conservation, agriculture, regenerative agriculture or soil health farming, he says we’ve got to adopt these practices so we don't destroy all of our soil resources.

Don's early research involved describing crop response and water use on conventional till and no-till systems with and without irrigation and later focused on tillage and crop biomass management as related to global change issues with emphasis on measuring carbon dioxide and water losses following intensive tillage with a portable chamber.

The short-term tillage-induced gaseous losses of carbon were related to the volume of soil disturbed in the tillage operation and help explain the long-term decline in soil carbon associated with intensive tillage agriculture. These results suggest need for improved Conservation Agriculture Systems for enhancement of soil resources and environmental quality that resulted in numerous international invitations. In retirement, he continues to write about Conservation Agriculture Systems, soil carbon management and environmental issues and to travel and talk about carbon cycling and carbon management in agricultural production systems.
