Effect of vegetation type and elevation as determined by multivariate analysis of variance (MANOVA) (F- values, with <i>p</i> in parenthesis) and two-way ANOVA on the concentration (mg kg⁻¹) of different phosphorus (P) fractions in humus soils along an elevational gradient in Abisko, Swe

For all variables, degrees of freedom for V = 1,36, E = 5,36, V*E = 5, 36. Bic = Bicarbonate; Pi = inorganic P; Po = organic P. aData were log transformed prior to analysis. bSum of Resin P, Bic-extractable Pi and Bic-extractable Po. cSum of all sequentially extracted P fractions.
