Project:
Priming Effect in the Rhizosphere of Maize: Mechanisms and Field Relevance
Supervisors: Yakov Kuzyakov and Johanna Pausch

Research interests
- Rhizosphere priming effects
- Rhizodeposition and nutrient (im-) mobilization
- Plant-microbial competition for nutrients
- Land-use change and belowground soil processes
- Exoenzyme activities in rhizosphere at temporal and spatial scale
- Implementation of stable and radioactive isotopes (14C, 15N, 33P, δ13C)
