a Permanent total reduction of N-input
b When measure is allocated on sites with specific soil conditions (fens/bogs or hydromorphic soils)
c For measures located on cropland a N-reduction of 60 kg N/ha*a is calculated (according to reduction rate of fallow fields), for measures on grassland
30 kg N/ha*a. It is assumed that hedgerows/herbal strips cover about 10 % of the cropland; therefore, the N-reduction potential is, related to the entire field
area, relatively low
d For hedgerows/groups of shrubs on cropland a N-reduction of 60 kg N/ha*a is calculated, according to reduction rate of fallow fields. Single trees (e.g.
fruit trees on grassland) have no N-reduction effects
e N-reduction depends on status quo. For measures on cropland 60 kg N/ha*a is calculated (according to reduction rate of fallow fields), for measures on
grassland 30 kg N/ha*a is calculated, measures on other land use types have no N-reduction effects
f Value points for upgrading or (in case of maintenance measures) for prevention of degradation
g The effects on reduction of CO 2 -emissions are not assumed as considerably high
h Shortcuts of biotope types and habitat value (I-V) according to NLWKN ( 2012 ) e. g. A (cropland), G (grassland), I (intensively used), E (extensively
used), F (rivers, small streams), and average upgrading of biotope value (0-4)

measure as well as maintenance; costs for renaturation of water bodies are calculated per 100 m of Fließgewässer and include a buffer strip of 5 m
