The influence of some soil factors on the mean heights of Norway spruce stands in the age of 100 years (determined on the basis of the dominant height of the stand) was assessed on 148 experimental plots on the whole territory of Slovakia. The strongest correlations were recorded in the depth of the humus layer. The significant correlation was also found with the proportion of skeleton, the soil acidity and humus content. The optimum soils from the point of view of Norway spruce height growth are those with soil pH/H2O = 5,16 (pH/KCl = 4,42) in A-horizon and pH/H2O = 5,60 (pH/KCl = 4,70) in the depth of soil 15 -- 20 cm, low skeleton and humus content. There are also some differences in stand height among stands, growing on the soils belonging to different soil types. The Rendzinas, Podzols and Dystric Cambisols proved to be the least suitable for the point of view of the height growth of Norway spruce.
