Duration: 01/05/2015 – 30/04/2018
The project aim is the investigation of the impact of long-term farming strategies (intensive and extensive) on the soil microbiome and its function in terms of soil suppressiveness against plant pathogens. In addition, the associated rhizosphere microbiome will be analyzed considering plant characteristics (model: lettuce).
We expect to gain new insight into soil and rhizosphere microbiomes, as well as their functions involved in soil disease suppressiveness. This knowledge will allow the evaluation of farming strategies for optimizing soil functions regarding certain bacterial and fungal taxa that demonstrate positive effects on soil health, especially on the suppression of pathogens. Finding indicators for soil suppressiveness will allow the evaluation and optimization of farming strategies. Root exudate components with consistent beneficial effects on plant growth and inhibitory effects on pathogens can open new perspectives for practical application. The socio-economic part of the research enlightens consequences and interpretations of political regulations in the field and delivers recommendations for bioenergy decision-making.
