Smyle (Avenella flexuosa) - avling, gjenvekst og fôrkvalitet
Avenella flexuosa is the main pasture plant in blueberry mountain birch forest and dwarf birch— blueberry moorland, which covers large parts of outfield pastures in the mountainous region of southern Norway. Four sites in blueberry mountain birch forest in Vingelen, Tolga, Hedmark, was fenced in and...

Avenella flexuosa is the main pasture plant in blueberry mountain birch forest and dwarf birch— blueberry moorland, which covers large parts of outfield pastures in the mountainous region of southern Norway. Four sites in blueberry mountain birch forest in Vingelen, Tolga, Hedmark, was fenced in and harvested at different times in summer 2014. Regrowth was also recorded. The grass from sample plots was dried after harvest, and analyzed for feed quality using NIRS.
