Statistical Survey

The main objective of this study was to investigate the causes of nutrient deficiency symptoms in Norway spruce (Picea abies [L.] Karst.) underplantings in the Hrub&yacute; Jesen&iacute;k Mts. In the area concerned 19 research plots were established, representing the ridge sites of the 8th FAZ of acid edaphic categories. On these plots samples were taken from topmost soil horizons and needle samples were collected in two series &ndash; from healthy and from damaged trees. The results of this study demonstrate that the nutrient deficiency symptoms and reduced vitality of evaluated underplantings were caused by the insufficient uptake of main nutrients (Mg, P, K, N<sub>t</sub>). High contents of toxic elements Al, S in damaged needles are another factor that negatively influences the health status of these underplantings.<br />A statistical survey showed that damage to underplantings increased with decreasing proportions of main nutrients (N<sub>t</sub>, Mg, Ca, K) in organomineral horizons. At the same time the content of basic nutrients (N<sub>t</sub>, Mg, Ca, K) was found to increase in this horizon with an increasing proportion of oxidizable organic carbon (C<sub>ox</sub>). The proportion of humus substances and the content of basic nutrients (N<sub>t</sub>, Mg, Ca, K) in organomineral horizons become a limiting factor for the normal growth and development of Norway spruce plantings in the ridge part of the Hrub&yacute; Jesen&iacute;k Mts.

The Impact

An empirical model is presented to forecast the incidence of butt rot at the stand level. In addition, the impact of different thinning regimes and stump treatment on the incidence of butt rot was evaluated. The model is based on data from 166 permanent forest yield research plots of pure even-aged Norway spruce (Picea abies (L.) Karst.) plantations in Denmark, within which the incidence of butt rot at stump height in thinned trees has been recorded after each thinning since 1947. In total, 79 000 stumps from 895 thinnings were studied. Regression analyses were carried out with the incidence of butt rot at a given point of time as the dependent variable and variables describing site, stand, and silvicultural treatments as the independent variables. Predictions carried out with the model imply that Norway spruce planted on old hardwood forest sites show the fastest development of butt rot and that the more heavily or more often a stand is thinned, the faster will be the development of butt rot. Furthermore, stump treatment with urea or sodium nitrite and thinnings carried out during January–March reduce the rot development.

Altitudinal Zone

The soil is an irreplaceable component of forest ecosystems. Soil-forming processes directly influence element cycling (EC). Plant-soil interaction is a specific part of EC. Plant-soil interactions were observed on an example of natural spruce stand (NSS), semi-natural spruce stand (SNSS) and allochthonous spruce stand (ASS) in conditions of the spruce forest altitudinal zone (1,140&minus;1,260 m a.s.l.; +3.0&deg;C; 1,200 mm) of the Hrubý Jeseník Mts. (Czech Republic, Central Europe), where Norway spruce (<i>Picea abies</i> [L.] Karst.) is the main edificator and stand-forming tree species. We evaluated the soil properties of H- and Ep-horizons at selected sites with Haplic and Skeletic Podzols and they were compared with the nutrient status of spruce. A method of the principal component analysis was used for definition of the basic hypotheses: (1) each forest stand is in specific and topically individual interactions with soil and these interactions influence its state, (2) the influence of forest management reflects in humification and in the nutrient status in plant assimilatory tissues. Cluster analysis calculated results comparable with the multivariate analysis of variance. The results show that the continuity of linear and multivariate statistical methods gives the approach to detection of the forest stage based on soil and plant tissue data.
