Virtanen, Luukkanen 2012: The Variation of the Amount of Inorganic Constituents in Some Common Mire Plants During the Vegetative
Theme IV. Chemical, physical and biological characteristics of peat
Seasonal changes in the inorganic elements of the mire plants common in peat such as Sphagnum fuscum, Eriophorum vaginatum and Ledum palustre were studied in eastern Finland. The first sample collection was made 12th May and the last one 13th October 1992. Altogether 19 elements Al, B, Ba, Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Ni, P, Pb, S, Sr, Ti, V and Zn were analysed. The concentrations of Ca, K, P and Mg, effect as nutrients, increased considerably during the vegetative season. The consentration of B, Ba, Cu and Mn is much higher in the mire plants than in the surface peat, where as Al, Pb, Sr and Ti exist in greater quantities in the surface peat compared with the plants.
