Research Soil Scientist
Research Soil Scientist, USDA-ARS, Mandan, ND
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 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.
- Cropland Production Systems: Quantification of conservation management effects on soil properties and processes in rainfed cropping systems.
- Grazing Land Production Systems: Quantification of soil property dynamics in response to grazing and fire management.
- In-Field Soil Assessments: Application of Visual Soil Assessment methods to semiarid agroecosystems.
- Long-Term Agroecosystem Research Network: Facilitate collaborative adaptive management framework for ‘Business as Usual’ and ‘Aspirational’ treatments as part of the Northern Plains LTAR Croplands Common Experiment.
All research seeks to provide information and guidance to create a more sustainable agriculture.
