Table 3 Mean values of chemical properties of sandy Dystric Arenosols and sandy loam Endostagnic Umbrisols in the grassland sites

From: Effects of afforestation of agricultural land with grey alder (Alnus incana (L.) Moench) on soil chemical properties, comparing two contrasting soil groups

Significant differences between soil chemical properties of studied soils are highlighted, differences are significant (p < 0.05) according to 1-way ANOVA post hoc Tukey’s test and Dunnett’s T3 correction. p values are shown: ** p < 0.01; *** p < 0.001; n.s. not significant
