Ertragsbildung von unterschiedlichen Kulturarten für dieBiogaserzeugung im ökologischen Landbau
2009
Energy crops for biogas production need to be integrated into sustainable and site
adapted crop rotation systems, minimising the competition with food production.
Luzerne/clover (-grass), sun flower, maize, green-rye + maize and vetch-rye + maize
were compared at two sites in Austria with semi-arid (Raasdorf) and humid (Lambach)
conditions with and without biogas slurry application. The yield of legumes and
fertilised non-legumes at the humid site were 9 % to 56 % higher then at the semi-arid
site. The 2-crop system maize following vetch-rye achieved the highest yields at both
sites. Slurry from the biogas plant increased the yield only at the humid site.
