“…Although high N-deposition in Europe has led to an increase in the abundance of M. caerulea (Aerts & de Caluwe 1989), the species is also regarded as having limited ability to respond to increased N-availability (Vázquez de Aldana & Berendse 1997). Studies have also shown that M. caerulea responds positively to increased availability of P on both calcareous and acidic soils (James 1962;Loach 1968). It stores large amounts of N in its roots and basal internodes (Pfadenhauer & Lütke Twenhöven 1986;Taylor et al 2001), and the reduced concentration of N observed in the above-ground phytomass when P is added could indicate that increased availability of P results in more N being allocated to the root system, not to increased growth.…”

Abstract. Rich‐fen vegetation influenced by hay‐making in the Sølendet Nature Reserve, Central Norway, was fertilized with N, P and K in a full‐factorial fertilization experiment to investigate the nutrient limitation of plant growth at both community and species levels. Above‐ground biomass, shoot density and nutrient concentration were measured in several species and groups of species at three sites after two years of fertilization. At the community level, the results indicate multiple limitation by N and P in the two least productive rich‐fen communities: one characterized by small sedges and herbs, and the other by high abundance of Menyanthes trifoliata and tall sedges. Increased nutrient availability had no effect on a more highly productive, tall‐growing, spring‐influenced community, indicating no nutrient limitation. The results at the species level correspond well with those at the community level, indicating multiple limitation by N and P in most of the dominant and sub‐dominant species. However, P seems to limit growth more than N in Succisa pratensis, and N seems to limit growth more than P in Carex panicea. Furthermore, Eriophorum angustifolium seems to be limited by K. The results did not show which nutrient limits the growth of Carex dioica, C. lasiocarpa and Trichophorum cespitosum. Indications that growth in low‐productive, boreal rich‐fen communities is generally limited by P was not confirmed.

“…James (1962) carried out pot experiments in a cold glasshouse with seedlings of M. caerulea grown in John Innes no. 1 potting compost made using an acidic loam (pH 5.4) unmodified or modified by the addition of CaCO 3 or CaSO 4 , to determine the factors which might bring about the natural exclusion of the species from well‐drained calcareous soils.…”
