- Abstract:
- We will characterise effects of N deposition, and its removal, on soil nitrifier populations at upland sites (heath, forest, improved/unimproved grassland) using 15N and molecular analyses. 15N pool dilutions will estimate rates of specific N transformations. Molecular techniques (16S rRNA gene sequences, DGGE, competitive PCR, 13C-labelling of DNA) will indicate compositional and activity changes in autotrophic ammonia oxidisers induced by, or which occur during recovery from, N deposition. Analyses of amoA genes in autotrophic and heterotrophic nitrifiers, and the use of specific inhibitors of ammonia oxidation, will allow contributions of heterotrophs to be assessed. Outputs will provide information for mechanistic models of soil N cycling.
