Abstract

In the County of Rostock spruce covers at present about 17 % of the total wooded area and cultivation shows an increasing tendency. Here, spruce grows out of its natural range of distribution. Eighteen sites without groundwater and stagnant moisture were selected for investigations into the relations between site factors and height growth of spruce. Growth was found to be regulated primarily by the Ca content in soil and this by N mineralization. The Ca content insoil closely correlated with the proportion of loam in soil. The supply of nutrients (P, K, Mg, Cu, Zn, Mn) and water improved as the proportion of loam in soil increased. It is suggested on the basis of analysis to subdivide the medium nutrient status M as defined by site mapping into M and M. Spruce growing should first of all by concentrated upon sites of type M with almost optimum growth conditions.
