Opis:: The work presents the evaluation of a measuring system consisting of a radar giving information on actual distance covered by a tractor and a computer interface archiving measurement data. The measuring system was installed on the Ursus MF235 tractor. The research was carried out for selected ground types, on which tractor wheels move in a forest nursery: asphalt, green fallow, and technological tracks next to sowing ridge. Obtained results allowed determining suitability of this radar for measuring distance covered by tractor or its speed in open forest nurseries. Obtained data shows that the number of pulses generated by the radar per distance unit depends on the angle of radar position relative to the ground. The highest accuracy was reached while the radar was set at the angle of 40-45°.
W pracy przedstawiono ocenę system pomiarowego składającego się z radaru dającego informację o przebytej drodze rzeczywistej przez ciągnik oraz interfejsu komputerowego archiwizującego dane pomiarowe. System pomiarowy zainstalowano na ciągniku Ursus MF235. Badania przeprowadzono dla wybranych podłoży po których poruszają się koła ciągnika w szkółce leśnej: asfaltu, ugoru zielonego, ścieżki technologiczne obok grzędy siewnej. Dzięki uzyskanym wynikom możliwe było ustalenie przydatność tego radaru do pomiarów drogi czy prędkości ciągnika w otwartych szkółkach leśnych. Otrzymane dane pozwalają stwierdzić, że ilość impulsów jakie generuje radar na jednostkę drogi jest zależna od kąta ustawienia radaru do podłoża. Przy ustawieniu radaru pod kątem 40-45° osiągnięto największą dokładność.

Opis:: This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters in two – and three-year seedlings of common beech and the occurrence of mites (Acari) in soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. The beech seedlings on the plots where compost had been used as fertiliser were significantly taller than those growing on the plots where mineral fertilisers had been applied. Mulching increased the height of the seedlings significantly only in the last, third year of the study. The tallest three-year-old seedlings were found on the plots in which both of the tested procedures had been carried out. Neither of the factors under study had a significant effect on the diameter of the root neck in the second year of the nursery cultivation, but they increased it significantly in the third year. Fertilisation with compost with an addition of pine-tree bark increased the number of leaves per plant and the leaf area in two – and three-year-old seedlings. A beneficial and significant effect of mulching on these parameters was found in the third year of cultivation. A significantly positive effect of mulching on the mite gathering density was recorded in the second year of the nursery cultivation. However, both of the experimental factors had a positive effect on the occurrence of those arthropods in the third year of the study. Oribatid mites were the most numerous mite order and they were found in the greatest density on plots where mulching had been applied. Fertilisation and mulching increased the Oribatida/Actinedida ratio, which may indicate an improvement of the biological balance in the soil environment.

Opis:: Przemysław Szmit
The aim of this study was to examine the effects of pruning the root system and different doses of nitrogen fertilization on the height and root collar diameter of 2-year-old beech seedlings (Fagus sylvatica L.). This research was conducted in the forest nursery Muchów (Jawor Forest District, regional directorate of State Forests in Wrocław) and two different pruning treatments (no pruning and at 12 cm depth) and nitrogen fertilization doses (25 and 50 kg×ha-1) were applied. Results from an ANOVA showed statistically significant differences between the two pruning treatments (p = 0.000) as well as for the interaction of both treatment factors (p = 0.019). Root collar diameter correlated with seedling height, both of which were significantly different for the two pruning treatments (p = 0.000). No statistically significant impact by the nitrogen fertilization doses on seedling height could be observed (p = 0.125). To conclude, we found that it is reasonable to reduce the doses of nitrogen fertilization to half the recommended amount, 25 kg×ha-1, if the root system is not pruned during the second growth year. Seedlings that do receive pruning should be fertilized using the recommended nitrogen doses.

Opis:: The use of biostimulants (amino acid containing protein hydrolysate) in forestry field has re- ceived much less attention so far than in agriculture. Promising evidences were reported in literature with useful application for nursery activities, stimulating early growth and reducing transplanting stress. This study investigates the potential benefits induced by an amino acid-based animal-derived protein hydro- lysate biostimulant (Siapton® by Isagro) in containerized Eucalyptus globulus seedlings following transplant- ing. Foliar and soil drench applications were applied using two different concentrations each (2.5 ml.l−1 and 5.0 ml.l−1 for foliar, 10 ml.l−1 and 20 ml.l−1 for soil). Measures on seedling height, apical shot formation, total aboveground (dry weight of leaves and stem) and belowground biomass (dry weight of roots) 120 days after transplanting were made to quantify the effect on growth. The contrasts analysis on results revealed a positive effect of the biostimulant on many of the measured parameters, especially with foliar application using the lowest concentration (2.5 ml.l−1). The foliar application was overall suggested as more efficient than soil drench also allowing lower inputs (i.e. biostimulant quantity). The main consequence of the treatment was an increased biomass allocation in the stem (above ground biomass) due to a stimu- lated leaves production which might suggest an increased photosynthetic activity and growth. Conversely no influence was detectable on total height of seedlings neither on the collar diameter. The biostimulant treatment on containerized Eucalyptus globulus positively influenced some features of seedlings’ growth after transplanting and the use of biostimulant with foliar application during the hardening phase in the nursery, appears to be a promising technique to potentially improve seedling growth after transplanting. An inter- esting impact from application of biostimulant on biomass accumulation following transplanting was here demonstrated. Anyway, further research to verify the results on different tree species as well as under open field conditions is envisioned.

Opis:: Abstract. For the period from the 1st of May to the 30th of October 2014, the water balance for Scots pine, Norway spruce, Pedunculate oak and European beech seedlings in a plantation setting was analysed. The experiment was conducted at the container nursery in the Rudy Raciborskie Forest District, Poland. Water was supplied by natural rainfall as well as a by small-droplet irrigation system and two automatic weather stations combined with 32 rain collectors were used to monitor rainfall throughout this research. Rain gauges were located 25 cm above the metal pallets and 10 cm below the nursery containers. An average of 987 mm∙m-2 of water reached the plantation, of which 53% were provided by the irrigation system. Most water was supplied to the oak field, whereas least was given to the spruce plantations and the irrigation water amounted to 535 liters and 422 liters per square meter, respectively. The amount of water percolating through the substrate was approximately 50–65%, depending on the tree species. An average sum of evapotranspiration at the container nursery was estimated to amount to 520 mm∙m-2 during the growth season leading to a total water balance of +463 mm.

Visualization and quantification of peat substrate moisture by fully automated moisture controlling system (SMCS) in forest container nursery. Forest Research Papers. 79. 317-325. 10.2478/frp-2018-0032
Opis:: This study explores the use of fully automatic monitoring system of peat moss substrate moisture under pine seedlings at Rudy Raciborskie forest nursery in the Silesian Upland. A brand new multipoint system for this study was created. The multichannel electronic recorder MPI-DN Metronic was the main part of the project. Twelve HD3910.2 probes (three electrodes) for volumetric water content measurement were used in a distributed configuration. Modbus RTU protocols were used for data transmission and the results were archived into an internal memory. One probe delivers 1440 measurements a day. Based on the average substrate moisture data from the field, the recorder controls the watering system according to the precisely defined parameters. Proper placement of sensors in the field allows for accurate analysis of the temporal and spatial variability of peat moss substrate moisture. Results of the statistical analysis have confirmed that the peat moss moisture is significantly differentiated within the homogeneous production field of the forest seedlings. The study findings suggest that irrigation systems should be adapted to specific situation of substrate moisture at the nursery surfaces aimed at optimised water management.

Wydawca:: The Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in Sekocin Stary
Opis:: Pruning is one of the important cultural treatments that have potential to influence hardwood seedling morphology. The aim of the study was to compare the growth of pedunculate oak seedlings, performed pruning roots, in the second growing season, fertilised full and reduced dose of nitrogen. A total of 24 experimental plots, each with an the area of 0.04 ha, were designated. The roots pruning were made at the end of February 2014 using root pruning machine EGEDAL. The fertilisation, for all seedlings, was performed using ammonium nitrate in an amount of 25 kg ha−1 of nitrogen. The second fertilisation was performed only for variants 2 and 4. For these variants, urea was used in an amount of 25 kg ha−1. At the end of the growing season, the root collar diameter and the height of seedlings were measured. A dose of nitrogen affects the height of pruned seedlings. The effect of the full dose of nitrogen on the height of the pruned seedlings was a statistically significant (p ≤ 0.05). There was no statistical difference in the height of the seedlings without pruning, fertilised with different dose of nitrogen. Analysis of root collar diameter showed the significant differences between the variants. The Tukey test, at the significance level of p ≤ 0.05, showed a significant impact on the root collar diameter of pruned seedlings but no proven effect of nitrogen fertilisation. To conclude, we found that it is reasonable to reduce the doses of nitrogen fertilisation to half of recommended amount (25 kg ha−1) if the root system is not pruned during the second growth year. Seedlings that has received pruning should be fertilised using the recommended doses of nitrogen.

Opis:: This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters for two - and three-year-old Scots pine trees and on the incidence of mites (Acari) in the soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. Organic fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark resulted in a significant increase in the plant height and the diameter of the root neck in two-year-old pine trees. The effect of mulching on these parameters was not significant. The synergistic effect of the factors on the plant height and the diameter of the root neck was not significant. Organic fertilisation significantly increased the height of 3-year-old pine trees, whereas it did not have a significant effect on the root neck diameter. Mulching increased the plant height significantly, but no statistical effect on the diameter of the root neck was demonstrated. Although no significant interaction of either experimental factors in their effect on the plant height and the diameter in the root neck was observed, the parameters tended to increase in the experimental option, which included organic fertilisation and mulching. Mulching had a significant effect on the presence of soil mites, especially oribatid mites (Oribatida). Their density increased greatly after the procedure. This growth, as well as an increase in the ratio of Oribatida to Actinedida could be a sign of improvement of the biological balance of the soils under study and their biological activity.
