Nitrogen Release in Pristine and Drained Peat Profiles in Response to Water Table Fluctuations: A Mesocosm Experiment

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.

	Löytynlähde	Mesocosms
		Min–max (phases 0–4)	𝑛 (phases 0; 1–4)
DON (μg L^−1)	≤600 (analysed 2009)	Min–max: 315–2181	0; 78
NH4^+-N (μg L^−1)	≤4 (analysed 2009)	Min–max: 19–4041	14; 80
NO2^− + NO3^−-N (μg 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.
