Opis:: Nawożenie jest jednym z najważniejszych zabiegów agrotechnicznych w uprawie kontenerowej materiału szkółkarskiego roślin ozdobnych. Każdy z nawozów należy stosować w ściśle określonej dawce, dostosowanej do potrzeb pokarmowych roślin. W pracy przedstawiono wyniki, aplikacji nawozów do kontenerów za pomocą aplikatora polskiej produkcji Strzelec firmy Kwazar. Badania prowadzono na różnych nawozach występujących na europejskim rynku handlowym, przy różnych ustawieniach skali na dozowniku. Wyniki przedstawiono w postaci wykresów.
Fertilizing is one of the most important agro-technological treatments in the container cultivation of the gardening materials of the ornamentals. One should apply every of fertilizers in closely determined dose, adapted for needs of nutritional plants. At the work results were presented, of application of fertilizers into containers with the applicator of the Polish production Sagittarius of the company Quasar. They were carrying out research on different fertilizers being found in a European commercial market, at different placing the scale on the dispenser. Results were presented in the form of graphs.

Opis:: The ‘Tisovik’reserve, located in the Belarusian part of the Białowieża Forest, holds an isolated relic stand of silver fir, situated 120 km to the north-east of the main forest. In order to preserve this relic fir stand, a ancestral conservative tillage consisting of the Jd 92 trial (plot I) and the Jd 94 trial (plots II and III) was established between 1992 and 1994 in the Polish part of the Białowieża Forest on the territory of the Hajnówka Forest District. The growth and development of the progeny of 20 firs were characterized by means of long-term observations made in these trials. In 2000 (at the age of 18), the firs in the Jd 92 trial (plot I) reached an average height of 394.86 cm with a mean diameter at breast height of 42.42 mm and the average rate of survival amounted to 75%. In the Jd 94 trial, the rate of fir survival on plot II was 70% (at the age of 15) with an average height of 277.08 cm and a diameter at breast height of 36.62 mm, while on plot III only 50 trees with an average height of 198.6 cm and a diameter at breast height of 24.49 mm survived. The results of this study show that the fir progeny in the ‘Tisovik’ reserve is of high breeding value. Therefore, the silver fir seed stock of the ‘Tisovik’ reserve is suitable for the establishment of new plantations in the Polish part of the Białowieża Forest and the Mazury-Podlasie Region.

Opis:: The aim of this research was to characterise the influence of plant spacing on the survival and growth of pines in dry and fresh coniferous forest habitats after almost 40 years since stand establishment. In this study, we compared seven types of spacing, including square, rectangular and triangular configurations, with initial densities ranging from 6944 units/ha to 15 625 units/ha. The research covered two sites where no tending interventions of selective character were performed throughout the growth period. We found that habitat conditions had an influence on tree survival as well as growth in thickness and height in the pine forest stands. In the less fertile habitat, where competition between trees was less intense, about 1,5 to 2 times more trees survived than in the more fertile habitat. Pines growing in the fresh coniferous forest were taller and had substantially larger diameter breast heights (dbh) in comparison to pines of the dry coniferous forest. Additionally, habitat conditions had an influence on the spacing effect correctness of the analysed features. In the poorer habitat this influence was stronger, which showed in a greater differentiation of the analysed parameters as compared to the more fertile habitat. Average dbh values of all trees on the Płock surface increased with decreasing initial density and ranged from 8,24 cm in variant A (15 625 units/ha) to 9,79 cm in variant C (6944 units/ha). On the Łąck surface, trees growing at a lower density (variants C and E) were significantly thicker than trees growing at densities between10 000 units/ha and 15 625 units/ha (spacing variants A, B, F, G). Furthermore, our results showed a significant influence of habitat conditions and plant spacing on the thickness of pines belonging to the 1st biosocial class. Moreover, we found a positive influence of triangular-shaped spacing on the trees' thickness increment in the fresh coniferous forest, which confirms reports from other authors. Hence, we can deduce that triangular spacing enables trees to make better use of their surrounding space which positively impacts on their growth parameters. Based on these results, we can conclude that, in pine forests, there is a significant influence of habitat conditions on tree survival and growth in thickness and height. This study also showed significant differences between the types of plant spacing and their effect on pine shafts in the II age class. However, a relationship between height growth rate and initial density was not observed. In both of the investigated habitats, the highest trees were observed at densities around 11 500 units/ha with triangular spacing enhancing this effect.
