Wild and cultivated plant mixtures are plants with a targeted combination of wild and cultivated plants typical of the location.
The mixtures promote biodiversity, provide refuges for beneficial organisms and improve the soil structure. They are used in flower strips as species-rich vegetation.
Biogas wild plant mixtures (WPM) contain annual, biennial and perennial flowering and predominantly wild plant species that are suitable for use as a biogas substrate but have not yet been utilised as such. The WPM can significantly reduce tillage intensity over five to seven years. No pesticides are used, with the possible exception of herbicides in the year of sowing. Even with lower annual biogas yields from WPM compared to maize, WPM can therefore loosen up maize-emphasised crop rotations and enhance them from a variety of social and ecological perspectives (food for pollinator insects, habitat for small game, groundwater protection, landscape).
