Water-use Soil melioration and Cultivation processes for drought-prone sites 2006-2009

Global climate change will further increase irregular distribution of rainfall and rain fall paterns. Regions in central Europe already suffering from long summer droughts are prone to more severe stress situations in the years to come. One way to decrease the severity of drought events and to increase the duration of sufficient water availability is  the use of meliorates in the soil

  • Quantify the effects of different soil meliorates and enhancers on the water holding capacity of the soil and the effects on plant growth (Field trial Cottbus)

  • Evaluate the effects of different soil enhancers on drought responses of different plant species of the group of renewable energy plants (Greenhouse in Bonn and field trial in Cottbus)

  • Evaluate the effect of seed coat composition on germination and early draought responses of several plant species from the group of renewable energy plants.

The project is financed by BMBF, the project leadership is located at the BTU in Cottbus, the subproject 2.2 is conducted as a collaboration between University of Bonn and University of Hohenheim.
