Combined Food and Energy system (CFE)
! Objectives ! Multifunctional cropping system ! Organic management ! Integrated production of food, energy and ecosystem serbvice ! Fossil energy neutral agro-ecosystem
• Components of CFE • Food – wheat/barley/oat • Fodder – Clover with rye grass • Trees - willow/alder/hazel nut
• Area coverage is 11.1 hectare • 10.1 hectare of food/fodder • 1 hectare of biomass/biofuel belts
