    Opis:
    The thesis presents the analysis of development of selected parameters of microclimate in a standalone cellar plunged into soil. The scope of studies included measurement of air internal and external temperature and relative humidity of internal and external air. The thesis also concerns the analysis of heat exchange of cellar compartments with the surrounding soil. The studies were carried out from July 11, 2012 to July 10, 2013. The analysis of the obtained results of studies proved that the internal air temperature in the examined cellar was mainly formed by the external air temperature as well as by the surrounding soil. For 42% of storage period, the thermal conditions in the cellar plunged into soil were unfavorable which disqualifies the cellar’s purpose for storage of vegetables, e.g. potatoes. Too high temperature was observed in the initial and final period. Favorable storage conditions were experienced only in the period from December 14, 2012 to April 11, 2013. To adjust this kind facility for storage of vegetables, thermal insulation of compartments and installation of cooling units is required.

    Opis:
    Basis of the study was made up of the results of automatic, hourly measurements of air temperature and bare soil temperature originating from the agrometeorological station in Lipnik (53o21’ N; 14o58’ E, 30 m AMSL) from the period of 2001-2005. Basing on the results of the linear regression analysis, relationships for particular months were determined between daily soil temperature at four depths and air temperature set in seven different combinations. It was stated that the highest possibilities of daily soil temperature prediction in profile to 50 cm are characteristic for the air temperature that is the average from 24 hourly measurements. Average absolute differences between the actual soil temperature and the one calculated from equations for this relation oscillate in the particular months between 1.3oC at the depth of 5 cm and 0.5oC at the depth of 50 cm. On average, the smallest differences apply to the warm half of the year and the depth of 50 cm. It was shown that significantly smaller possibilities of the estimation of daily soil temperature values are characteristic for daily air temperature amplitude.
    Podstawę opracowania stanowiły wyniki automatycznych, cogodzinnych pomiarów temperatury powietrza oraz temperatury gleby nieporośniętej, pochodzące ze stacji agrometeorologicznej w Lipniku (53o21’ N; 14o58’ E, 30 m n.p.m.) z okresu 2001- -2005. W oparciu o wyniki analizy regresji liniowej oceniono związki dla poszczególnych miesięcy, pomiędzy dobową temperaturą gleby na 4 głębokościach a temperaturą powietrza ujętą w 7 różnych kombinacjach. Stwierdzono, że największymi możliwościami predykcji dobowej temperatury gleby w profilu do 50 cm odznacza się temperatura powietrza będącą średnią z 24 cogodzinnych pomiarów. Średnie bezwzględne różnice między rzeczywistą temperaturą gleby a obliczoną z równań dla tego związku wahają się w poszczególnych miesiącach od 1,3oC na głębokości 5 cm do 0,5oC na głębokości 50 cm. Przeciętnie najmniejsze różnice dotyczą ciepłej połowy roku i głębokości 50 cm. Wykazano, że zdecydowanie najmniejszymi możliwościami szacowania dobowych wartości temperatury gleby odznacza się dobowa amplituda temperatury powietrza.

    Opis:
    W pracy przestawiono analizę dobowej zmienności temperatury i wilgotności powietrza w okresie wegetacyjnym w dwóch siedliskach w rejonie Bydgoszczy. Wykazano duże zróżnicowanie wartości, przebiegu w ciągu doby i rozkładu pionowego w przyziemnej warstwie atmosfery: temperatury, wilgotności względnej, ciśnienia pary wodnej i niedosytu wilgotności powietrza. Przyczyną tego zróżnicowania jest uwilgotnienie siedliska glebowo-wodnego oraz pokrywa roślinna. Zmienność temperatury i wilgotności powietrza w ciągu doby i ich pionowy rozkład powodują, że zależności parowania wody od średniego dobowego niedosytu wilgotności powietrza są różne w badanych siedliskach.
    The paper presents analyses of the variability of air temperature and humidity in the growing season at two sites in the Bydgoszcz region. The values, daily course and vertical distribution of air temperature, relative humidity, vapour pressure and vapour pressure deficit were different in the near ground layer of atmosphere. The moisture of soil-water site and plant cover are the reasons of this variability. Daily variability of air temperature and humidity and their vertical distribution are responsible for different relationships between evapotranspiration and vapour pressure deficit in the studied sites.

    Opis:
    A unique, highly time-resolved, and synchronous three-year dataset of near-surface atmospheric radon-222 as well as soil heat flux and air temperature measurements at two sites (rural and urban) in Central Poland are investigated. The recognition of temporal variability of Rn-222 and selected meteorological variables in the urban and rural areas served to create two statistical models for estimation of this radionuclide concentration at 2 m a.g.l. The description of the relationships between the variables for individual months was established on the basis of an exponential function and an exponential function with time derivative of predictor to account for the hysteresis issue. The model with time derivative provided better results. The weakest fitting of modelled data to empirical ones is observed for the winter months. During subsequent seasons, air temperature as well as QG-driven (soil heat flux) models exhibited very high agreement with the empirical data (MBE, RMSE, MAE, and ‘index of agreement’ by Willmott were used to evaluate the models). A restriction in the use of QG for Rn-222 concentration was observed only in winter in the case of snow cover occurrence, which reduces the daily QG variability.

    Opis:
    Soil erosion by water is one of the most important factors affecting contemporary landscape changes within the lowland geoecosystems in Central Europe. Soil erosion by water mainly depends on: rainfalls (especially its intensity and erosivity), length of slope and its inclination, type of cultivation and usage of land, anti-erosion treatments and susceptibility of soils to erosion. The aim of conducted research was to evaluate conditioning and magnitude of secular and extreme soil erosion processes in the Drawsko Lakeland with special considering of rainfall erosivity index (EI30). The main goal was realised through several research tasks. The first task involved examination of surface runoff and slope wash conditionings, course and quantity in the testing plot located within the Chwalimski Potok catchment. The second task was related to evaluate rainfall impact to soil erosion by water processes. It was realised by computation rainfall characteristics: intensity, kinetic energy and erosivity. In order to assess secular and extreme soil erosion impact to land relief changes, research were provided with additional details by conducting three field experiments with simulated rainfall. Stationary observation and quantitative researches of soil erosion (at testing plots) have been conducting within the Chwalimski Brook catchment for three hydrological years (2012–2014). The slope with the test area is located within the 1st order catchment being a subsystem of the Młynski Brook catchment and then followed by the upper Parsęta catchment. This area covers 4.8 hectares and is characterised by short slopes with small height variances up to 10 meters. Historically, the area was covered with agricultural crops, currently they cover about 10% of the area. The slope is covered with gleyic retisols and its average inclination is about 4 degrees with its south-east exposure. The measuring system of soil erosion covered 5 testing plots with different agricultural use (bare fallow, meadow, potatoes, spring and winter crops). Plots are 42 metres long and 4 metres width. In the bottom edge of each plot catchers with volume of 800 dm3 were installed. In this research, only data from black fallow were considered. Such tillage is recognised as a standard in soil erosion studies. Two experiments have been conducted in this testing plot. The third one has been conducted on slope located within an area of undulated morainic plateau in the Kłuda catchment. The slope is characterised by greater height variances than in Chwalimski Brook catchment. The slope, where the experiment has been conducted, is situated within local closed depression and is covered by sands underlain by boulder clay. Its average slope is about 10° with its southwest exposure. Although annual precipitation in the three-year measurement period was comparable with mean value from multi-year period (1987–2014), its intensity and erosivity were distinguishably lower. Such rainfall conditions are not favourable for extreme soil erosion by water processes, thus any relief forms from such geomorphological processes were not observed in the Drawsko Lakeland. Due to lack of that kind of forms, in 2013 and 2014, three field experiments were conducted. The main aim of experiments was to evaluate the impact of high intensity rainfall on soil surface. The first experiment consisted of 5, the second and the third of 4 rainfall simulations. The rainfall was created by using a purpose-built rain simulator, consisting of 3 and 6 sprinklers placed around the testing plot. Despite the slope inclination in the Kłuda catchment was 2.5 times steeper than Chwalimski Potok’s slope, surface runoff attained smaller volume, because of remarkably higher infiltration rate. In 2012–2014, surface runoff and soil loss has occurred 8 times each year. The maximal monthly surface runoff volume was registered in February 2012, and it equalled 10.1 dm3 m−2 and the maximal soil loss value was registered in May 2013 and equalled 3,198 kg ha−1. Annual runoff volumes were between 31.2 dm3 m−2 in 2012 and 38.8 dm3 m−2 in 2013, whereas annual soil loss values ranged from 740 kg ha−1 in 2012 to 5,700 kg ha−1 in 2013. Soil erosion values caused by simulated rainfall during field experiments were similar or significantly higher than annual values. Surface runoff was between 31.2 dm3 m−2 in the first experiment and 34.2 dm3 m−2 in the second one, whilst soil loss was between 4,632 kg ha−1 and 8,637 kg ha−1. The achieved experiment results have been compared with soil erosion rate achieved from stationary observations. The results show that runoff and soil loss considerably increase during rainfalls with high amount, intensity and erosivity. Furthermore, individual extreme erosive events may exceed annual (secular) soil erosion processes. Conducted stationary research indicates that annual soil erosion primarily depends on individual rainfall and erosive events, which considerably exceed mean values. In order to evaluate the soil susceptibility to erosion by water in the Drawsko Lakeland, high resolution potential and actual soil erosion risk maps were prepared. The qualitative assessment of soil erosion risk was based on geoinformation technologies. The model considers following conditions affecting the size of soil erosion: slope steepness and aspect, topographic factor LS (unit upslope contributing area), lithology, rainfall erosivity (Modified Fournier Index calculated from monthly and annual precipitation data) and land use and land cover from Corine Land Cover 2006. To prepare the map of potential soil erosion risk, land use from Corine Land Cover was not considered. Thematic maps have been reclassified into a 4-degree division. The results of the soil erosion risk assessment in the Drawsko Lakeland reveal the fact that a majority of its area is characterized by moderate or low erosion risk levels. Areas with high erosion risk are mostly located in the northern part of the Lakeland. The achieved results from stationary observations and field experiments may indicate that the soil loss magnitude significantly increases during rainfall with higher intensity, greater totals and accumulated in time rainfall events. This may confirm the high potential of soil erosion by water processes of above- -average magnitude and intensity in the discharge of material from agricultural used slopes.
