ENERGY INVESTIGATIONS OF DIFFERENT INTENSIVE RAPE SEED ROTATIONS – A GERMAN CASE STUDY - Economics of Sustainable Energy in Agriculture - page 28

The total area related energy savings in the 'Integrated' systems of
the first project period amounted to 25.9 % and 24.6 %
( Reinshof and Marienstein resp.) compared to the references (Table 3.4). In
the second project period the saved area related energy in 'Integrated
flexible' amounted to 31.4 % and 31.8 % ( Reinshof and Marienstein resp.).
'Integrated without plough' was even slightly better (36.5 % and 35.0 %
resp.). If annual set aside is excluded, the advantages in energy use for the
integrated systems in the second project period are much smaller (Table
3.4, lower lines Int-a, Int-b). Furthermore the energy input in the reference
systems

of the second project period became slightly lower (-5.6 %
