    Opis:
    The study was conducted in the Bydgoszcz Forest (Cierpiszewo Forest District) in the area of the lowest precipitation in Poland. In 4 plots (3 of rotary tiller and 1 – the comparative one – of plough soil preparation) measurement of Scots pines (Pinus sylvestris L.) and dry biomass of ground vegetation as well as soil investigations were performed. The best height and radial increment of pines were stated in the comparative plot (the soil cultivated by a plough) in spite of the distinct lowest of all plots soil moisture and nutrient stocks occurring there. The differences in plant growth can be explained by much more effective reduction of competition of ground vegetation in young plantations by a mouldboard plough than by a tiller. The results can also be explained by occurrence of unfavourable water conditions in rows prepared by a tiller during dry periods. The soil material in the rows is enriched in organic matter that results in increasing water repellence when it is dried. Rotary tiller should be recommended for soil preparation in the study area but on condition of successful ground vegetation removal from young pine plantations in some first years after planting.

    Opis:
    The research was conducted in a young Scots pine (Pinus sylvestris) plantation located in a dune area of the Toruń Basin (N Poland). The aim of the study was to investigate differences in dynamics of soil water conditions followed different method used for site preparation. The three plots were investigated in the study: belt of soil prepared by a mill, north−facing slope of a dune (FR−N), belt of soil prepared with a mill, south−facing slope of a dune (FR−S) and soil prepared with a plough (furrows) on the ridge of a small aeolian mound (LPZ). On each plot soil samples were taken and soil moisture was regularly measured from April to December of 2013 (the TDR method). The measurements of soil moisture were taken at four depths (3, 10, 25 and 50 cm) at intervals of ca. 2 weeks. Additionally, soil moisture was also measured on 25.08.2015. It was done to determine soil water conditions for a deep summer drought (the measurements were taken twice this day – just before and after rain which turned to be the first since ca. a month). Reserves of soil moisture and shares of water unavailable to plants were calculated for every measure day for each study plot. As a result of higher organic carbon content, values of soil actual moisture as well as reserves of soil moisture were almost regularly higher for belts mixed with a mill than for furrows prepared with a plough (fig. 1, 3). Opposite relation was found, however for the summer drought (tab. 2). This was explained by the higher repellence of rich in organic mater, dried material occurring in belts. On 25.08.2015 much lower improvement of water conditions after rain was also stated for this material than for topsoil in LPZ. Unfavoured soil water conditions for plants occurring in belts in dry periods could explain relatively low dynamics of pine growth revealed for the variant of soil preparation in a previous study. However, it was concluded that a forest mill should be recommended for forestry, because the device much less disturbs topsoil than a plough. Besides, differences in growth parameters of pines followed different methods of soil preparation used before planting decline in next years of a stand growth.

    Opis:
    The objective of the study was to determine the dynamics of soil temperature on inland dunes in the Toruń Basin (N Poland) with reference to the two methods of site preparation: homogenization of belts with a forest mill (FR) and preparation of trenches with a double−mouldboard plough LPZ−75 (LPZ). The study was conducted in a young Scots pine (Pinus sylvestris) plantation on plots with soil prepared by a forest mill on north− and south−facing slopes of a dune (FR−N and FR−S respectively) and with soil prepared with a plough on the ridge of a small aeolian mound (LPZ). On each plot a soil pit was dug and soil samples were taken from distinguished horizons for laboratory analyses. Besides, from April to December of 2013, at interval of ca. two weeks, soil temperature was measured at the depths of 3, 10, 25 and 50 cm. To estimate daily amplitudes of temperature in topsoil on the studied plots, in a sunny summer day (23.08.2013) the temperature was additionally measured from 5 a.m. to 9 p.m. with an hourly interval. These measurements were taken at the two upper depths (3 and 10 cm). Despite the fact that soil surface was distinctly darker for belts prepared with a mill than in trenches prepared by a plough, soil temperatures were almost regularly lower in FR−N and in FR−S than in LPZ. This concerns all the investigated depths. The differences were explained by much higher moisture of soil material in belts what involves higher thermal capacity and with that slower heat of a soil, as well as causes higher losses of thermal energy for evaporation. Another agent explaining this was indicated to be related to high porosity of materials found in the belts. Namely, especially in dry periods, high volume of soil pores are filled on the FR plots with air what impedes heat transfer in a soil. It was concluded that stated in a previous study worse growth of pines planted in milled belts than in tranches prepared with a plough was unlikely related to differences in soil thermal conditions. Thus, differences in growth dynamics of young pines in plots with site prepared by the two studied methods are caused by other reasons rather as primarily other competitive impact of weeds and differences in soil water conditions occurring at root system of young trees.
