Matt Madsen

Research Scientist

 U.S. Department of Agriculture, ARS

 

Dr. Madsen is a Research Scientist with the USDA-Agricultural Research Service in Burns, OR.  He received his BS (2004) in Watershed and Earth Systems and his MS (2006) in Soil Science from Utah State University. His PhD (2009) was from Brigham Young University in Wildlife and Wildland Conservation. He joined the research group at the Eastern Oregon Agricultural Research Center in May 2010.

His current research is focused on understanding the limiting factors to rangeland reseeding success, and in the use of seed coating technology for developing innovative reseeding approaches for overcoming these limitations.

 Research Objective

The primary objective of Dr. Madsen’s research program is to determine the limiting factors controlling rangeland-reseeding success, and utilize this knowledge in the development of methods and technologies that result in the establishment of functional plant communities.  Linked objectives include: 1) quantifying the role and impact of edaphic, climatic and biotic factors (e.g., drought, seasonal temperature change, water repellency, crusting soils, salinity, weed competition), on rangeland reseeding success and plant productivity; 2) determining how barriers to restoration success vary at both individual plant and landscape level; and 3) develop and or identify seed enhancement technologies (e.g., seed coating, pelleting, deterrents, biological and physiological treatments, and other non-traditional methods) that are capable of mitigating ecological processes and conditions limiting plant establishment.
