Using weeds as a source of bioenergy
They have names like field bindweed, ragweed or couch grass – but poppies and corncockle count amongst them as well. For farmers, all these plants are weeds. Nature conservationists, on the other hand, speak of wild herbs or 'arable flora'. Many weeds are becoming increasingly resistant to herbicides, hindering the growth of actual crops in the process. The consequences can already be measured in terms of lower harvests.
