Abstract:
In a long term trial at four Bavarian sites the production of maize silage and winter wheat is examined whether their production as substrates for the conversion pathways biogas and biomass to liquid can be sustainable. Therefore a crop rotation with maize and wheat is grown over a period of 10 years (kickoff 2009) with and without the removal of straw both fertilized with mineral fertilizer. Additional variants comprise different levels of organic fertilization by biogas digestates and cattle slurry. Extensive surveys concerning soil humus content as well as humus fractions, soil texture, soil stability, soil fauna and its activity in the soil complete plant cultivation data. Changes in soil characteristics will be verifiable by the end of the monitoring, so that a final rating of the different production techniques considering their long¬term applicability is possible. Results of the first three years are presented in this paper.
