About the Project:
Project Aim
Investigations are focused on basic mechanisms of plant–soil-microorganism interactions as a function of crop rotation, soil type, fertilization and amendment as well as temperature and moisture. These results will support the improvement of soil functions, nutrient-use efficiency of crop production, and the development of optimized agricultural management strategies.
Motivation
Excessive fertilizer use in agriculture leads to nutrient imbalances, which are the cause of nutrient losses leading to surface and groundwater pollution as well as increased greenhouse gas emissions. A sustainable agriculture has to find ways to minimize this nutrient inefficiency, while maintaining or even increasing crop productivity and quality. Motivation is the development of novel plant cultivation strategies directed towards “engineering” the complex nutrient cycling interactions between plants and soil microorganisms, combined with improved timing of fertilizer and soil amendment applications.
Expected Results
This interdisciplinary project supports the knowledge-based evaluation of potentials to optimize plant-microbial interactions and to improve the nutrient-use efficiency in agricultural crop production. The evaluation and characterization of these interactions directly supports the developed of new agricultural management strategies to reduce nutrient losses and environmental pollution. The synthesized knowledge helps to maintain and improve the soil functions and services of agricultural cropping systems even at regional scale.
