Responses of Ammonia-Oxidising Bacterial Communities to Nitrogen, Lime, and Plant Species in Upland Grassland Soil

Table 2

ANOSIM 𝑅-statistics for pairwise comparisons of chemical treatments (lime, nitrogen, lime + nitrogen) and plant species (unplanted, A. capillaris, L. perenne) on ammonia-oxidising bacterial communities. NT, no treatment. All comparisons were significant (𝑃<.005).

Treatment/Plant groups	𝑅-statistic
NT, Lime	0.382
NT, Nitrogen	0.819
NT, Lime + Nitrogen	0.708
Lime, Nitrogen	1
Lime, Lime + Nitrogen	0.852
Nitrogen, Lime + Nitrogen	0.535
Unplanted, A. capillaris	0.568
Unplanted, L. perenne	0.477
A. capillaris, L. perenne	0.755
