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.
- Integrated Crop-Livestock Production Systems: Determination of production and environmental tradeoffs associated with integrated crop-livestock management.
- Cropland Soil Health: Quantification of conservation management effects on soil properties and processes in rainfed cropping systems.
- Rangeland Health: Quantification of prairie dog activity effects on soil resistance across diverse ecological sites.
- In-Field Soil Assessments: Application of Visual Soil Assessment methods to semiarid agroecosystems.
- Long-Term Agroecosystem Research Network: Establishment of ‘Business as Usual’ and ‘Aspirational’ treatments as part of the LTAR Croplands Common Experiment.
All research seeks to provide information and guidance to create a more sustainable agriculture.
