Table 6 P content in aboveground biomass (mg P kg⁻¹ soil) in the HK Kalke (a) , UCPH (b) and CULS (c) experiments

a Data were analysed by two-way ANOVA. Data were log-transformed prior to statistical analysis due to unequal variances (Brown–Forsythe test, P < 0.05). Tukey’s post hoc test was used to test whether there was a significant difference in P uptake between the different P fertilisers within the BE0 treatment. For each P fertiliser, values in bold italics are significantly higher than the BE0 treatment and values in italics are significantly lower than the BE0 control according to Dunnett’s test
b Data were log-transformed prior to statistical analysis due to unequal variances (Brown–Forsythe test, P < 0.05)
c For each of the two soils independently, Tukey’s post hoc test was used to test if there was a significant difference in P uptake between the different P fertilisers within the BE0 treatment. Small letters indicate differences for the Humpolec soil, while capital letters indicate differences within the Poděbrady soil. For each row, values in bold italics are significantly higher than the BE0 treatment and values in italics are significantly lower than the BE0 control according to Dunnett’s test (one-way ANOVA with data for straw ash and wood ash)
^aDifferent letters indicate means that are significantly different
