Mark A Liebig

Research Soil Scientist


Research Soil Scientist, USDA-ARS, Mandan, ND

Co-PI, Northern Plains LTAR

Adjunct Faculty, Department of Soil Science, North Dakota State University


Dr. Liebig works with a multidisciplinary team of scientists to develop soil, crop, and animal management practices for the Great Plains to overcome limitations to productivity while maintaining or enhancing environmental quality.  As a team member, he leads basic and applied research to quantify management effects on soil properties and associated ecosystem services.  In addition to core research responsibilities, Dr. Liebig develops decision aides and evaluation tools for producers, conservationists, and scientists, and regularly contributes to research networks within and outside USDA-ARS.


All research seeks to provide information and guidance to create a more sustainable agriculture.
