Table 4: Concentrations of nitrogen fractions in Löytynlähde spring water and the range (min–max) in the water samples from the mesocosms at phases 0–4.

LöytynlähdeMesocosms
Min–max (phases 0–4) (phases 0; 1–4)

DON ( g L−1)≤600 (analysed 2009)Min–max: 315–2181 0; 78
-N ( g L−1)≤4 (analysed 2009)Min–max: 19–404114; 80
+ -N ( g L−1)600 (analysed 2009)Min–max: 6–283 0; 80

Values are from all samples from both controls and manipulated mesocosms. Phase 0 samples were taken at the end of the low water table and phases 1–4 samples were taken during the high water table.
