- Abstract:
- Early impacts of oxidised and reduced N on a blanket bog community with low ambient N (8 kg N ha-1y-1) will be investigated by treatment with simulated wet N deposition as NaNO3 or NH4Cl and dry deposited NH3 in air providing inputs of 8 to 48 kg N ha-1y-1. Assessments will be made of plant species composition and abundance, mycorrhizal infection in ericoids, vitality and ability to withstand stress, photosynthesis, water relations and nutrient uptake in vascular and non-vascular plants. Results will be used to determine critical loads/levels for the different N forms and identify areas of UK blanket bog at risk from N deposition. The use of P and K amelioration to mitigate adverse N effects will be evaluated for the different N forms.
