The objective of the paper is to assess the effects of amphibolite powder (waste from a dust removing process in <br />a rock pulveriser) and Silvamix slow release fertiliser on Norway spruce plantation in the harsh physical environment of the Jizersk&eacute; hory Mts. The plantation characteristics such as mortality, annual height increment, stem base diameter, crown diameter and nutrient analyses are evaluated. A nine-year-long period of observation is summarised. The effects of both the forms of chemical amelioration seem to be positive and statistically significant. The benefits of the amelioration expressed in absolute figures have been easily observable until now. Recently, the importance of these benefits has decreased after the adaptation of planted trees to the mountain site and natural acceleration of their annual increment.

The subject of this paper was to assess the effects of pulverised dolomitic limestone applications on prosperity of Norway spruce (Picea abies L.) plantation and on the soil in extreme ecological conditions of the Jizersk&eacute; hory Mts. The characteristics such as plant mortality, annual height increment, diameter of root collar (stem base diameter), crown diameter, nutrient analyses and some data from soil analyses are evaluated in this paper. An eleven-year period of observations is summarised. According to the observations and measurements carried out until now, the effect of limestone applications (1 kg per tree) on the spruce plantation prosperity seems to be positive without any serious negative impacts on the soil.

We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted mountain site. Control plots and treatments with slow-release fertiliser (SRF) and amphibolite (AMT) were installed. In the SRF, forty grams of tabletted amendment were applied in the close vicinity of the trees. In the AMT, two kilograms of amendment were incorporated into the soil inside the planting hole of each tree at planting. The SRF application resulted in a significant growth stimulation of spruces. The growth stimulation by amphibolite was perceptible but not significant; this amendment, however, significantly reduced mortality. None of the amendments induced marked changes in foliar nutrient concentrations. &nbsp;

The aims of the paper were as follows: (1) to assess the applicability of speckled alder for pioneer stands on the mountainous clear-cut tracts and (2) to evaluate the effects of slow-release fertilizer on the survival and growth of speckled alder under harsh environmental conditions. On the basis of seven-year results we can presume that speckled alder is a convenient pioneer species that can be cultivated on harsh mountain sites where the climatic extremes need to be alleviated and a layer of surface humus renewed. The initial slow-release fertilization is, nonetheless, highly desirable. As contrasted to the control the surface and planting hole applications of amendment reduced the total seven-year mortality rate by 9.5% and 20.1%, respectively, and the periodic annual height increment (2003&ndash;2009) was promoted by 47% and 59%, respectively. Analogous results were obtained when the values of basal stem diameter and crown diameter were compared. As for the method of application, the placement of the slow-release amendment in the planting holes seems to be more efficient mainly in terms of survival promoting. The surface application is, nonetheless, less laborious and also yielded satisfactory results.&nbsp; &nbsp; &nbsp;

Annual Shoot

The annual shoot elongation could be described by a non-linear growth model to characterize differences in its dynamics among spruce genotypes, the effect of each shoot elongation phase on the total shoot length, and the genetic differences for a particular growth phase. The terminal shoot length was measured in two open-pollinated progeny trials of Norway spruce on average once per week during the ninth growing season. For the analysis, 10% of families with the longest annual increment (shoot) and 10% with the shortest were selected for each trial. The Gompertz model was fitted to individual tree data, and the mean values of its coefficients for each group of families were obtained. Family significantly (p < 0.001) affected total shoot length and all growth rhythm parameters, with similar trends reported in both studied sites. Heritability of Gompertz model coefficients in most cases exceeded that of the tree height. The superior10% of families started shoot elongation slightly but non-significantly earlier (all p > 0.05) than the other groups of families and had more intense shoot elongation (mm per day) during the entire growing season. A strong negative relation was found between the slope coefficient of the cumulative shoot elongation lines and the total height increment. The group of families with the longest increment had flatter relative shoot elongation lines, indicating relatively more evenly distributed growth within the growing season. In contrast, families with the shortest increment tended to accumulate a higher proportion of height increment during the active growth phase and reduced relative growth intensity more rapidly. The 10% of families with the largest annual increment showed superior characteristics in all shoot elongation phases, resulting in 30–40% longer shoots compared to the 10% of families with the smallest annual increment. The significant differences in Gompertz model coefficients indicate that genotypes with favorable growth patterns might be selected.

Speckled Alder

A young speckled alder (<I>Alnus incana</I> [L.] Moench) stand was planted on a tract clear-felled due to air pollution and located on a summit plateau of the Jizerské hory Mts. (Central Europe, Czech Republic) at an altitude of 950 m a.s.l. The aim of the experiment was to test the suitability of <I>Alnus incana</I> to form preparatory stands covering the site and thus enabling the reintroduction of more sensitive target species. A potential of <I>Alnus incana</I> to respond to slow-release fertilizing was tested as well. The control treatment showed sufficient growth dynamics, nevertheless, the fertilization significantly promoted the growth (documented by height, height increment and stem-base diameter). If some limitations of alder such as high light requirements are respected, the speckled alder can be recommended as a suitable species for preparatory stands even in the 7<sup>th</sup> and 8<sup>th</sup> altitudinal (vegetation) zones, especially when fertilized.

The aim of this study consisted in verifying the hypothesis whether the application of tableted fertilizers Silvamix® Forte, Silvamix® R, Stromfolixyl® and calcareous dolomite affected significantly the nutrition and growth of Norway spruce. In order to carry out research investigation, the experimental Suchdol locality has been selected as it represents large‑scale reclaimed sites in the Krušné hory Mts. Ameliorating agents were applied using the initial spot fertilization of Norway spruce plantations. In the course of two years, activities as follows were carried out annually: (1) top shoots measurement, (2) sampling the latest needle year‑class. The applied fertilizers impact on the concentrations of nutrients in needle dry matter was not significant with minor exception. Fertilizers Silvamix® Forte and Silvamix® R can be recommended to support seedlings growth in the area of interest since there had been positive effect on annual height increment found out. Calcareous dolomite showed the most favourable effect on the shoot biomass growth. Stromfolixyl® fertilizer had no effect on the annual increment; its impact on the nutrition can be characterized as insignificant since fertilized individuals showed lower phosphorus concentration in needle dry matter.

For 17 Norway spruce stands located in the Krkonoše Mts. in the Czech Republic a long-term assessment of defoliation, height increment, foliage concentration of nutrients (N, P, Ca, K, Mg) and stress elements (S, F) was carried out. The results show a decrease of defoliation and a slight increase of height increment, which occur in accordance with the decreasing concentration of sulphur in spruce needles. However, neither sulphur concentration nor height increment trends are significant, suggesting that both the main pollution abatement and the growth resumption took place already in the 1990’s. During the late 1990’s the average spruce defoliation was greater than 35%, while since 2007 it has fluctuated between 18 and 25%, which corresponds with the figures for the forest stands located in the other regions of the Czech Republic. The evaluation of single nutrient concentrations detected occasional deficiencies of P and Mg at individual plots. The good N nutrition (&gt; 15 mg N·g<sup>–1</sup>) in combination with a significantly decreasing trend of P, K and Ca concentrations in Norway spruce needles may potentially constitute a problem in regard to both the future health and the stability of forest stands in the studied region.

One of the most important stand productivity and competition indicators is height annual increment, which is affected by various factors such as soil preparation, initial density as well as various management risk factors. Empirical material for the research was collected in the northern part of Latvia. In four pure Scots pine stands in Myrtillosa forest site type 29 circular plots tree diameter, height and the last five years annual height increment was measured and visual state of health was described. The aim of this research is to analyse Scots pine height annual increment in naturally regenerated young forest stands in Myrtillosa site type forest stands and to give an evaluation of the impact of the initial stand density and the health status on height growth. The mean height increment in studied stands is 0.26 ± 0.009 m and the average periodical increment is 0.37 ± 0.042 m. The annual height increment has been in the height range from 0.23 to 0.53 m. Initial stand density affects the annual height increment significantly. In the stand with an initial density of 5770 ± 961 trees the height increment during the last five years has risen by 36%, but in stand with initial density of 12,650 ± 1,581 trees (P = 51.8 % and R = 6.0 %) the height increment during the five-years period has increased by only 12 %. The tree health status does not affect the tree height increment significantly.

The present field experiment entitled ‘Nutrient management and carbon sequestration potential of the rubber-based intercropping system in Western Ghat region of Karnataka’ was conducted at farmers’ field of Harishi village of Soraba taluka of Shivmogga District, Karnataka, India during 2017 to 2019. The experiment was laid out in split-plot design with three replications. Two practices applied on rubber was the application of Farm Yard Manure (FYM) as an organic practice and NPK as inorganic practice and nine treatments consisting of different organic manures biofertilizers and NPK as inorganic fertilizer was applied on Bird’s Eye Chilli (BEC) grown as an intercrop. The results showed that application of NPK on rubber resulted in a maximum mean annual increment in basal diameter (0.56 cm) and crown diameter (0.28 m) in one-year-old rubber and height (0.77 m), basal diameter (0.62 m) crown diameter (0.21 m) in two-year-old rubber. Among nine treatment of BEC, application of NPK resulted in higher growth parameters of rubber at both age levels. Interactions were non-significant on all growth parameters. Age and different manures also influenced the carbon sequestration potential of the system. Hence the application of NPK may be recommended for cultivation of rubber.

The organic matter produced and accumulated by plants is a crucial component in the ecosystems on environmentally disturbed sites. The aim of our study was to evaluate the influence of initial fertilising on the aboveground and belowground tree biomass of Norway spruce. The biomass amount, distribution and chemical composition were studied in a young spruce stand growing on an acidified mountain clear-cut tract. The fertilised trees accumulated a higher amount of tree biomass. They nonetheless showed lower concentrations of P, N, and K in some root compartments than control trees, which could be ascribed to a dilution effect. As for the aboveground compartments, no significant differences in element concentrations were proved.
