SLIDE 4 This project has received funding from the European Union‘s Horizon 2020 research and innovation programme under grant agreement No 691874
Project coordinator Partners Sustainable exploitation of biomass for bioenergy from marginal lands (MagL) in Europe
Definition of MagL within the SEEMLA context
Land with poor site conditions due to low soil fertility and clear economic inefficiencies with regard to agricultural usability. Excluding:
with potentially high productivity set aside
temporarily abandoned due to certain socio-economic reasons
- badlands with naturally extreme low soil fertility as well as
most parts of brownfields or anthropogenic wastelands

Muencheberg Soil Quality Rating system (SQR), developed by Mueller et al. (2007), and applied by BTU-CS in pilot fields survey
Sites with calculated SQR scores below 40 indicate MagLs within the SEEMLA context.
