Fine-root response to nitrogen supply in nitrogen manipulated Norway spruce catchment areas

Investigations were carried out in order to assess the effect of decreased/increased nitrogen (N)- and sulphur (S)-deposition on the growth and vitality if fine-roots of Norway spruce ( Picea abies (L.) Karst.), in three catchment areas within the Lake Gårdsjön basin, SW Sweden. The catchment areas...

Zusammenfassung:	Investigations were carried out in order to assess the effect of decreased/increased nitrogen (N)- and sulphur (S)-deposition on the growth and vitality if fine-roots of Norway spruce ( Picea abies (L.) Karst.), in three catchment areas within the Lake Gårdsjön basin, SW Sweden. The catchment areas were subjected to decreased N- and S-deposition (G1 ROOF), increased N-deposition (G2 NITREX) and ambient levels of N- and S-deposition (F1 CONTROL). The excavated fine-roots (
