Forage quality parameters of differently treated meadow plots (control, +N, -25%, and +N/-25%) at the Elbe tributaries (oceanic site at the Sude and more continental site at the Havel River).

The plots were cut in June 2010 and 2011 (first cuts) and in September 2009, 2010 and 2011 (second cuts). Response parameters are biomass (g m-2), XF = crude fibre (% in dw), XP = crude protein (% in dw), DE = digestible energy (MJ kg-1 dw), ME = metabolisable energy (MJ kg-1 dw), NEL = net energy for lactation (MJ kg-1 dw), fructan (% in dw), N-, P-, K-contents (mg g-1 dw), and annual yield (GJ ha-1); dw = dry weight. Values are means (x) + SE. n = 7 for all groups. No differences were detected between treatments within sites and years, only between sites (right column).
