    Opis:
    Vertisol plasticity is related to moisture content, and it requires an in-depth physicochemical characterization. This information allows us to use the land under the most adequate conditions and avoid soil physical degradation, especially its compaction. The objective of this study was to characterize the Vertisol in the Moroccan region of Doukkala-Abda and to predict soil plasticity based on the physicochemical parameters of soil, such as texture, electrical conductivity, Soil Organic Matter (SOM) and other chemical parameters for 120 samples. Determination of soil plasticity using Atterberg limits is a challenging and time-consuming method. Thus, this study aimed to develop a new model that can predict soil plasticity using the Random Forest algorithm. The soils presented homogeneity in the majority of physicochemical parameters, except a significant difference observed in the SOM and the electrical conductivity, which in turn influenced the soil plasticity state. The results showed significant and positive correlations between SOM, Soil Clay Content (SCC), Electrical Conductivity (EC), and plasticity in the Vertisol fields of the region. For the training phase, the model gave excellent results with a coefficient of determination of 0.995 and an RMSE of 0.164. Almost the same results were observed in the validation phase with a coefficient of determination of 0.974 and an RMSE of 0.361, which shows that the model succeeded in predicting plasticity in both phases. On the basis of these results, this model can be used for the plasticity prediction using other physicochemical parameters and the Random Forest Model. The prediction of soil plasticity is an important parameter to respect the timing of introducing machines/tools in the fields and avoid Vertisol degradation.

    Opis:
    Geomechanical and hydrological surface deformation caused by the underground hard coal extraction leads to limited agricultural and natural soil use. The paper presents results of soil productivity indices determined in the area of post-mining subsidence depression near Libiąż. The algorithm of method suggested by Zhengi Hu et al. [1992] was used for the computations. The obtained results of field and laboratory analyses indicate soils degradation due to water logging and a necessity to undertake reclamation measures to restore their previous values. Determined productivity indices (PI) characterise the selected ground as the area with poor conditions for agricultural production. The reason for low PI values is a change in the soil properties because of degradation. The methods presented in the paper may be used to determine the degree of soil degradation in the areas of hard coal mining.

    Opis:
    Dryland farming, managed intensively, with the input of chemical fertilizers exceeding the dose threshold, can cause soil degradation. Degraded soil affects low environmental carrying capacity and soil and water conservation. Researchers conduct soil tests on agricultural land to address this issue, especially those that apply a continuous cropping system. This study aimed to examine soil properties to determine the conditions of soil degradation in dryland farming. The method integrates spatial analysis with Geographic Information Systems (GIS), field surveys, and laboratory soil samples analysis. The spatial data used to map the potential for soil degradation includes land use, slope, rainfall, and soil type. Integrating spatial and laboratory data, such as soil physical, chemical, and biological properties results in soil degradation status conditions representing the actual conditions in the field. This study found that there were three classes of soil degradation successively, namely mild, moderate, and high. There are two statuses of soil degradation, including non-degraded and light soil degradation status. The soils with a mild degree of degradation are due to the limiting factors of permeability, fractional composition, and total porosity. Some actions that can be taken include planning soil degradation prevention measures by utilizing soil degradation potential maps that have been made for areas with high soil degradation potential. For the sites with a status of soil degradation, efforts are made to start carrying out soil improvement actions in accordance with conservation principles to reduce the soil degradation that occurs. Moreover, organic matter is added to degraded and potentially degraded soils to increase the stability of soil aggregates and water-carrying capacity.

    Artykuł jest głosem w rozpoczynającej się dyskusji na temat kwestii związanych z minimalnym udziałem problematyki degradacji środowiska gleby w podstawie programowej zreformowanej polskiej szkoły. Również dość niskie wartości współczynników zdawalności zadań maturalnych w tzw. Nowej Maturze od roku 2005, osiąganych przez uczniów i dotyczących omawianej problematyki wskazują na potrzebę pilnych zmian w systemie edukacji ekologicznej polskiej szkoły ponadgimnazjalnej.
    Statement is a summary discourse on issues involving environmental degradation of the soil in the core curriculum reformed Polish school and its actual implementation. Also reviewed the coefficients pass rates of test tasks on the issues discussed at the Matura examination since 2006, together with an indication of the reasons for their low values.

    Opis:
    The soil resources in Kosovo are facing challenges due to different human activities. Urbanization, along with economic growth, has further worsened the shortage of soil resources in Kosovo. In the last 20 years, Kosovo has undergone some social, political and economical changes which have made the population to migrate toward plains, where new settlements are formed, and other are extended. Soil resources are important for Kosovo’s inhabitants, who are mainly focused on agriculture. Most of the Kosovo’s terrain is mountainous, which means nearly half of the area is not suitable for agriculture. The Sitnica River basin lies mostly in Kosovo Plain where soils are characterized by high fertility with a great potential for agricultural development. The vicinity parts of the river basin lie in the hilly mountainous areas where soils have low fertility. Good natural conditions have made the River Basin the most densely populated area in Kosovo. Rapid extension of urban and rural settlements changed the land cover; agricultural lands were excluded from primary use, and the agricultural capacity is reduced with the increasing number of settlements on lands with high quality. Sitnica River basin was faced with uncontrolled urbanization, followed by the degradation of agricultural lands and land use changes, where floods occur in some cases or the flood risk is increased. In this case study, the Sitnica River basin will be analysed based on terrain morphology, soil and other natural resources, land use changes and will be a contribution towards sustainable urbanization of settlements in order to preserve soil resources.

    Opis:
    As the main purpose of this article, the authors consider the level of soil pollution in the Aksu River basin as a result of anthropogenic impact, in which factors of anthropogenic transformation of soils in different zones play an important role, as well as processes occurring in soils as a result of their impact. This article highlights the research of the main analyses carried out, which showed that the anthropogenic transformation of soils within the surveyed territory is multifactorial and complex. As an assumed result, the validity of which is analyzed in this article, it can be considered that the degree and forms of manifestation of anthropogenic transformation of foothill soils depend on their use, as one criterion of which is considered the use of such soil for arable land, including irrigated arable land, in which the degradation of mountain soils is mainly associated with pasture loads during a certain period. As a research question, it remains to be considered whether this is really the case or whether the present territory is subject to a different anthropological impact.

    Opis:
    The subjects of this study were uncultivated mining waste heaps which are remnants of the territories abandoned after the exploration of iron ore. The aim of this analysis was the assessment of the influence of these objects on the soil located in the nearest surroundings, as well as estimation of the level of their degradation. It was ascertained that direct geomechanical degradation exists in the examined object, which is connected with soil profile destruction in consequence of transformation of hitherto existing geomorphological conditions, deformation of natural shape of territory, density of soil levels and deformation of the spatial layout. As a result of the examination, it was pointed out that chemical degradation as well as degradation of ecological structure occur on the analyzed territory. Progressing processes of water erosion on the side of waste heap are the consequence of improperly profiled, steep slopes causing the uncontrolled flow of rainwater, lack of flora and dense, micrograiny structure of soils which prevents the effective infiltration of water. Penetration of water into the ground causes the creation of channels which, in dry periods, can become additional pathways for the possible landslides.

    Opis:
    Struktury przestrzenne i sposoby użytkowania ziemi należy synchronizować z przyrodniczo-gospodarczymi warunkami, stosownie do bytowych i kulturowych potrzeb społeczności lokalnych i regionalnych. Gleba i szata roślinna stanowią biologiczną powłokę lądowej powierzchni ziemi. Bez gleby nie ma szaty roślinnej (fitosfery), tak jak bez szaty roślinnej nie ma gleby (pedosfery). W warunkach naturalnych obie wymienione sfery tworzą względnie stabilną (w czasie) biosferę, stosowną do jakości powierzchniowych utworów geologicznych (petrochemicznych), strefy klimatycznej (w tym klimatu lokalnego) i rzeźby terenu. Antropogenizacja powierzchni ziemi bezpośrednio i pośrednio zniekształca naturalne warunki środowiska. Likwidacja trwałej szaty roślinnej ba potrzeby uprawy roślin odsłania glebę na erozyjne działanie wód opadowych i wiatru oraz nasila dynamikę powietrza atmosferycznego i spływy powierzchniowe wód opadowych. Modyfikuje warunki klimatu lokalnego. Techniczna uprawa gleby czyni ją bardzo podatną na erozyjne działanie wody i wiatru. Techniczna zabudowa trwale niszczy biologicznie czynną powierzchnię ziemi, z daleko idącymi skutkami ekologicznymi. W rolniczej przestrzeni Polski dominują archaiczne struktury gospodarstw chłopskich, o niebywałym rozdrobnieniu powierzchni działek, daleko idąca degradacja systemów melioracji wodnych. Niezbędne scalenia gruntów są realizowane w znikomym zakresie. Leśna rekultywacja nieużytków i nieefektywnych gruntów rolnych, to główny czynnik wzrostu lesistości kraju, począwszy od roku 1949. Dzięki temu lesistość kraju zwiększyła się z około 20% do około 30% w roku 2010. Potencjalne możliwości zwiększenia lesistości są jeszcze bardzo duże, tym bardziej, że znaczna część nie użytkowanych gruntów rolnych została już samoistnie zadrzewiona (zalesiona) i zakrzewiona, czego nie ujmuje geodezja i statystyka.
    Spatial structures and land use patterns need to be synchronized with natural and economic conditions, at the same time taking into account social and cultural needs of local and regional communities. Soil and vegetation provide biological coating of land surface, as without soil there is no vegetal cover (phytosphere), and likewise, without vegetation there is no soil (pedosphere). Under natural conditions, both spheres aforementioned constitute the biosphere, relatively stable over time, and adapted to the quality of geological material at the land surface (petrochemical conditions), climatic zone (including local climate) and local relief. Anthropogenic impacts on land surface have direct and indirect effects visible as the deformation of natural conditions. Removal of vegetal cover without subsequent crop cultivation exposes soils to wind and water erosion and enhances the dynamics of atmospheric air and runoff of precipitation waters. It also modifies local climatic conditions. Technical cultivation of soils renders them vulnerable to erosive action of wind and water. Technical build-up irreversibly destroys the biologically active land surface leading to the far reaching environmental consequences. In the agricultural space of Poland there prevail both archaic structures of farmland with an unusual fragmentation of agricultural lots and advanced degradation of water melioration systems. Activities required to perform land merging have only been made to an invisible extent. Forest reclamation of waste land and non-effective agricultural land has been the main factor contributing to an increase in the country's forest rate since the year 1949. It is owing to that activity that the country's forest rate increased from some 20% to about 30% in the year 2010. Potential for increasing the forest rate remains very high still, the more that a considerable part of set aside farmland has been subject to spontaneous afforestation (woods and shrubs), what has not been registered by geodetic and statistical services.
