Other claims from this paper (8)
- Observation For length growth, 10 kg N ha−1 yr−1 was the optimal nitrogen deposition load.
- Observation For biomass production, 30 kg N ha−1 yr−1 was the optimal nitrogen deposition load.
- Intervention effect A nitrogen deposition load of 100 kg N ha−1 yr−1 almost completely inhibited elongation and biomass production.
- Intervention effect Increased CO2 concentration slightly reduced length increment of Sphagnum fuscum.
- Intervention effect Increased CO2 concentration had no significant effect on biomass production of Sphagnum fuscum.
- Intervention effect Increased CO2 concentration accelerated relative growth of Sphagnum carpets when they also received additional nitrogen.
- Observation Sphagnum fuscum shows a high degree of spatial variability in growth.
- Observation The present nitrogen deposition load in Southern Finland is quite suitable for growth and production of Sphagnum fuscum.
