Abstract:
The seasonal rhythm of height growth of young shoots of Scots pine growing in a 33-year-old shrubby-sphagnum pine forest of the northern taiga natural-climatic zone has been studied in a complex with the main physiological processes. The possibility of regulating their intensity by additional introduction of nitrogen fertilizer has been determined. It has been found that on hydromorphic excessively wet soils of the North, seasonal height growth of pine occurs with a maximum rate in late June and early July, when air temperature rises and the root system is released from excessive moisture. Unlike lichen pine forests, in which pine roots are not affected by flooding, on hydromorphic peat soils pine grows much slower and during the growing season has less intensive physiological processes. The low rate of shoot growth and physiological processes in pine in sphagnum forest site conditions is explained by dysfunction of its root system as a result of soil anoxia caused by flooding, as well as by insufficient supply of growing shoots with acronutrients from the crown as a result of violation of their normal outflow and movement in the tree. Nitrogen fertilizers positively affect growth and physiological processes in pine trees in sphagnum forest types. However, their effect in these forest site conditions is much weaker than in the dry lichen forests of the Far North. On water-logged peat soils under the influence of nitrogen fertilizer seasonal height growth of pine trees increases by 20 %, the duration of seasonal shoot growth increases by 8–10 days, the intensity of photosynthesis increases significantly, and, as a result of reduced water onsumption for transpiration, the tree water regime normalizes and the transpiration productivity increases. These positive nitrogen-induced changes ultimately improve the viability and productivity of sphagnum pine forests. For citation: Zarubina L.V., Khamitov R.S.

Abstract:
The purpose of the research was the adaptation of foreign technologies for intensive and accelerated cultivation of Scots pine planting material in Kazakhstan. Objects of research were annual seedlings of scots pine in forest nurseries of Pavlodar, Akmola, and North Kazakhstan regions. The experiments were established in 4 directions: application of dry growth regulators to soil, pre-sowing seed treatment with growth regulators, soaking seeds in stimulants and fungicide, pre-sowing watering of the soil with growth regulators. It was established that seed quality decreased significantly compared to the last year, only seeds from Pavlodar region had high indicators. Seeds from the nursery ‘Ertic Ormany’ had the highest average indicators of soil germination (58.7…67.8%). In ‘Bukhpa’, the highest germination was observed in seeds soaked with Zircon + Trichocin (3 + 2 hours). Baikal growth regulator and AridGrow slightly increased germination in the nursery of Arykbalyk branch of ‘Kokshetau’. In the forest nursery ‘Ertis Ormany’, the highest annual seedlings were obtained in variants with presowing treatment of scots pine seeds with stimulants and watering the soil with growth substances. The average height of experimental seedlings was 4.32 and 4.64 cm, respectively. The combined use of Zircon and Trichocin increased seedling growth in ‘Bukpa’ nursery to 1.42 cm, which was the highest value. It was revealed that the technologies used in neighboring countries for intensive cultivation of scots pine seedlings showed a positive effect only when using Citovit. According to other experiments, it was determined that seedlings of scots pine grown from seeds with pre-sowing treatment in Gumat+7 for 12 hours had the best growth indicators in height. Increased soil fertility through applying nitrogen, phosphorus fertilizers, soil activator AridGrow and KZ Cultury significantly accelerated growth of scots pine seedlings.

Abstract:
In 1985-88, a 25-yr-old Scots pine forest in Netherlands was limed (5 levels) and fertilized with P, K and Mg in a factorial design. This paper discusses the influence of P, K and Mg addition (as one treatment) and liming, on solute concentrations at depths of 30 cm, i.e. in the root zone (monitored September 1989 - April 1992) and 100-150 cm, i.e. below the root zone (April 1991). Liming increased NO3 concentrations at both depths. At 30 cm this effect of liming gradually vanished during the study period, concurrently with declining soil solution pH, while an increasing effect of PKMg on NO3 developed. Probably it took several years for nitrifying microflora to adapt to improved nutrient availability, while the effect of liming was instantaneous. These data show that besides liming, fertilization may increase NO3 leaching. NH4 was not affected by any treatment. Applied K and Mg compounds were easily soluble, and their soil solution concentrations were increased at both depths in PKMg-amended plots. Probably slow-release fertilizers would allow for a more efficient incorporation of K and Mg into the system's biomass. Reducing effects of liming on soluble Al were weak (30 cm) or absent (100-150 cm). Al at 30 cm did not reach concentrations known to be harmful to Scots pine, but Ca:Al ratios were critical in unlimed plots. No evidence was found for enhanced cation leaching caused by increased formation of nitric acid in limed plots.

Abstract:
Most seedlings and saplings of woody plants in the Russian Federation are produced in the open ground in forest nurseries. In order to produce high quality planting material it is necessary to support and preserve soil fertility, which can be obtained by using organic wastes and organic-based fertilizers. Our research is aimed at the assessment of the influence of non-conventional organic fertilizers on fertility of podzols and on the growth rate of seedlings and saplings of woody plants in forest nurseries. Our research shows, that the application of non-conventional organic fertilizers does not result in any accumulation of heavy metal salts in podzols, but optimizes hydro physical and agrochemical properties of the ploughed horizon. The efficiency of non-conventional organic fertilizers depends on their composition, physical and chemical characteristics of the original components, their doses applied and original fertility of soils. A combined application of non-conventional organic fertilizers and sand results in the optimization of practically all soil fertility parameters in middle clay-loam soils, while application of non-conventional organic fertilizers and clay is optimal for application on light soils. The optimal application dose of non-conventional fertilizers depends on soil texture, woody species and the fertilizer composition. An optimal application dose for Norway spruce on a light clay-loam soil is 50-80 tons/ha, and on a middle clay-loam soil is 149-182 tons/ha. It is 50 tons/ha for Scots pine growing on a sandy loam soil, and 100 tons/ha for the same species growing on a sandy soil or a light clay-loam. For Siberian larch growing on a light clay-loam soil the dose of fertilizer applied should be 150 tons/ha. It is recommended to apply composts containing over 50% (by weight) of Category II wastes (substrate) for the amelioration of light soils, and composts containing over 40% (by weight) of Category I wastes (filler) for the amelioration of heavy soils. It would allow for the optimization of soil properties and production of better quality planting material in forest nurseries.

Abstract:
The investigations were conducted in the frame of EU Research project Wood for Energy – a Contribution to the Development of Sustainable Forest Management (2001–2005). The integrated wood ash experiment was set up in a 38-year-old Scots pine (Pinus sylvestris L.) stand on Arenosols in SW part of Lithuania. Raw (not hardened) wood ash and nitrogen fertilizers were applied in 6 variants: 1.25 t ash/ha; 2.5 t ash/ha; 5.0 t ash/ha; 180 kg N/ha; 2.5 t ash + 180 kg N/ha and control (no treatment). The changes of soil pH, the content of some nutrients, heavy metals in Arenosols and soil solution, the abundance of ammonifiers, nitrifiers and denitrifiers in forest floor and mineral topsoil after the application of wood ash are presented and discussed in this paper.

Abstract:
In 1985-1988, a 25-yr-old Scots pine forest in Netherlands was limed and fertilized with P, K and Mg in a 24 factorial design and in an experiment with 5 liming levels, in order to alleviate potential nutrient deficiencies as a result of high N depositions (ca. 40 kg ha-1 yr-1). In this paper, effects of fertilization and liming on nutrients in forest floor and mineral soil are discussed as a basis for explanation of foliar nutrient concentrations and tree performance. Of all treatments, liming showed the widest array of effects, especially in forest floor: raised pH and lowered extractable Al in forest floor, and after 4 yr those in 0-50 cm mineral soil. These effects, except for that on forest floor pH, were stronger with increasing lime dosages. Liming showed transient effects on amounts of soil inorganic N (Ni). Until 1989, Ni in forest floor was lowered and that in mineral soil was raised by liming. This could be attributed to the formation of NO3, which is more mobile than NH4. Plots limed with 3 t lime/ha appeared to have higher Ni concentrations in the whole sampled profile than those limed with >3 t/ha or unlimed plots, the reason for which is unclear. Liming removed extractable K and Mg from forest floor probably by exchange against Ca. Residence time of added P and possibly Mg in forest floor was increased by liming, probably by solubility of added fertilizers. Added K was poorly retained in forest floor and probably quickly leached to soil layers deeper than 50 cm.

Abstract:
The annual cycle of arginine content in young and 1-year-old needles of 10-year-old Scots pine (Pinus sylvestris L.) was studied as related to various periods of nitrogen deposition into the soil at a high dose (300 kg/ha) and boron deposition in the optimal dose (3 kg/ha). Fertilizers were applied once, in June, July or August. The amino acid levels in young and 1-year-old needles of control plants remained similar throughout the study period (0.7±0.1 – 1.3±0.1 µmol/g absolute dry matter), with the peak in May. The placement of the fertilizers in the soil at three instances considerably augmented arginine content in young and 1-year-old needles during the first annual cycle following the impact. Nitrogen and boron application to the soil in June had the highest effect on arginine accumulation, primarily in young needles. The maximum amino acid levels were 618 ± 60 and 152 ± 15 μmol/g DM, 256 ± 24 and 154 ± 14 μmol/g DM, 132 ± 13 and 76 ± 7 μmol/g DM at the June, July and August fertilization in the young and 1-year-old needles, respectively. The seasonal patterns of arginine accumulation in coniferous plants, as well as the mechanisms through which nitrogen and boron influence this process are discussed.

Abstract:
Abstract The aim of the present work was to characterize the growth – climate relationship of pines growing in the Szczecin city forests in intensively used recreational areas and to identify the effect of air pollutants emitted by a nearby chemical factory on tree-ring width. Our research area was located in the Głębokie forest complex, which is one of the most frequently visited. The chemical factory Police that produces fertilizers is located at a distance 11 km away from the study plot. The largest emissions of pollutants from the factory in terms of volume occurred in the 1980s and early 1990s. Wood samples were collected from Scots pine (Pinus sylvestris L.) with the Pressler borer from 30 trees and examined using standard dendrochronological methodology. The result was a local chronology of 169 years from 1848–2016. Dendroclimatological analyses indicated that the weather conditions at the turn from winter to spring are the dominant factors influencing radial growth. For example, higher than average temperatures in February, March and April result in a wide tree-ring in the upcoming growth season. Following Nowacki and Abram’s method, we also determined the relative growth change in order to delimit the timeframe when air pollution potentially alters tree-ring width. Due to the lack of data for the period 1848–1945, the increasing and decreasing relative growth could not be linked to specific events. For the period 1944–1972 however, we observed and increase in the tree-ring width, which in this case can be attributed to favorable weather conditions. The final period, 1973–1991, on the other hand showed the strongest decline in annual growth throughout our chronology and this was largely due to the nearby chemical factories, which released huge amounts of pollution into the atmosphere during this period. At present, despite new technologies and a decrease in overall production by the nearby chemical factory, we found a negative trend in ring width dynamics indicating a need for pollutant monitoring and further research.

Abstract:
The effects of sewage sludge application and the additional effects of clearfelling on nutrient cycling have been assessed in a mature Scots pine stand, north-east Scotland. The forest site was situated in a low rainfall area with high evapotranspiration and low leaching losses. The ground vegetation formed an important sink for N and P following sludge addition and clearfelling. Sludge application caused a foliar N response, increased foliar needle weight, and litterfall showed a significant and rapid potential to immobilize NH4-N and PO4-P added in sludge. The soil availability of NH4-N and PO4-P together with rates of mineralization of N and P and nitrification in sludge-treated areas were significantly increased compared with that of the control. Concentrations of NH4-N, NO3-N, PO4-P and organic P were increased significantly following sludge addition and fluxes were an order of magnitude greater than that of the control. Peaks in concentrations of NH3-N in sludge-treated areas exceeded the EC limit of 11.3 mg 1-1 on several occasions. Of the total N and P applied to the sludge, throughfall and litterfall over a 17 month period, 2.4 % and 0.72 % were measured in the Bs soil horizon flux. After clearfelling, initial increases in soil availability of NH4-N, NO3-N andPO4-P were measured. Felling increased nitrification rates, although increases were significant only in areas previously treated with sludge. Fluxes of NO3-N, NH4-N and PO4-P and organic P were increased at least an order of magnitude greater in felled areas than those of the control. Immobilization of N and P was greater in green and abscised litters placed in previously sludge-treated areas than compared with those placed in control areas.
