Allocation of elements in former farmland afforestation with birch of varying age

Tomasz Gawęda , Stanisław Małek , Michał Zasada


Research on the effect of birch regeneration on changes occurring under its influence in former farmlands included quantitative and qualitative analysis of biomass growing on research plots. Five experimental plots were selected in the Mazovia voivodeship: in Dobieszyn and the Kampinos National Park - 2 plots in each, and in Kozienice - 1 plot. Analysis performed on each plot concerned the chemical composition and amount of biomass in four patches of vegetation, characterised by different ages of birch trees growing there. The vegetation patches were classified according to subsequent age groups: I: 1 - 4 years, II: 5 – 8 years, III: 9 – 12 years and IV: over 12 years. Biomass samples were obtained and weighed, determining in kg dry mass/ha its following elements: roots, stem, bark, branches, assimilation apparatus, litterfall and total biomass of the other (except birch) plants. For all groups mentioned above, the content of the following elements was determined: N, C, S, Ca, K, Mg, Na, P, Mn, Cu, Fe, Zn, Pb, Cd. This allowed for obtaining both the values of concentrations of particular substances and their allocation, in both the organic matter and litterfall. The aim of the analysis of the obtained results is to answer the question whether the allocation of elements changes with the age of birch growing on former farmland.
