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:: Five complex soil profiles in gully system on Nałeczów Plateau (E Poland) were examined. They represent the loess sediments modified by soil processes and postpedogenic transformations. Two examined profiles represent natural and mature Luvisols with diagnostic illuvial horizon (Bt argillic) developed on the edge of plateau geomorphologic level and in the relict valley bottom. The other soil profiles reflects postpedogenic soil degradation, redeposition and secondary accumulation (deluvia, colluvia and/or proluvia). Record of these processes are the micromorphological features created by lithological processes (=primary loess and secondary pedoliths) or by pedogenesis (mainly bioturbation, illuviation, de- and recalcification). The important group of microfeatures are pedorelicts which clearly confirm genetic dependences of pedoliths (deluvia and proluvia) and soils developed in situ and located in higher hypsometric levels in the catchment.

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.

Opis:: Human activities such as transport contribute to the environmental degradation. Therefore, the aim of the study was to determine the level of contamination of soils, from different districts of big cities of central Europe, with heavy metals: zinc, lead, and nickel. The samples were taken from the top, sodded soil layer. Each single sample weigh was about 1 kg taken from 1 m2 measuring station. Soil samples were dried at room temperature. The airborne dry soil was thoroughly mixed and sieved through a 1 mm nylon sieve. The study included analysis of which type of metals is washed out under the influence of abiotic factors (bioavailable forms) and demonstrating how spatial development affects the accumulation of selected heavy metals in the soil. The results indicated that heavy metals emitted to the ground layer of the atmosphere accumulate in the immediate vicinity of communication routes. Moreover, based on the analysis of interrelationships of zinc, lead, and nickel concentrations, it has been shown that there is a common source of their emission to soil. Furthermore, the thesis that the concentration of metals was dependent on the soil reaction was not confirmed.

Opis:: In the study, the content of heavy metals such as Pb, Cd, Ni, Cu, Zn and Mn in the soils collected from various regions of the Lublin Voivodeship was examined. The examined soils were light medium soils. Content of individual elements was determined by the AAS method in the extracts of 1 M HCl. The analysed soils were poor in copper and manganese. Their concentration and the concentration of lead, cadmium and nickel was in the lower realms of the range natural for light soils formed from sands. Only the content of zinc was fairly high in the above soils, frequently as high as the first degree of contamination.

Opis:: In the present paper, on the basis of altitude measurements, changes of topographic profiles of a chosen dried valley in Elizowkaon the arable land were presented. Intensity of water erosion was also studied on the unprotected loess terrain for 40 years.On the average, 22 cm of mud deposited on the tested section of the valley bottom (total area of 1.28 ha) along 500 m of the water race line, with the average width of 25.ʹ6 m. In consequence, the local erosion basis was raised and the average inclination decreased slightly. Physico-chemical properties did not significantly change within 40 years and these factors are typical of deluvial soils with unshaped profile. Their partial improvement points to reduction and stabilisation of erosion processes. That phenomenon is associated with slight thaw water run-off and the lack of larger storm precipitation.

Opis:: The issues discussed in the paper concern the assessment of changes in quantitative and qualitative indicators of water resources in the climatic conditions of the southern part of Kazakhstan. For this purpose, many years of systematic field observations and other continuous data obtained from the functioning measurement and observation stations operating within the Aral-Syrdarya Basin Inspection were used. On the basis of the obtained data, indicators were determined that characterize the quantity and quality of water supplied to the soil in the irrigation process, as well as the quantity and quality of water flowing out of the drainage systems, together with an evaluation of the effectiveness of irrigation and drainage systems. Soil salinity was assessed in five irrigated massifs with a total area of 332.55 thous. ha. For the same irrigated massifs, the annual amounts of water taken for irrigation, the amount of outflowing water and the assessment of the mineralization level were determined. Based on the developed results of field observations characterizing the hydrological and environmental situation of the lower section of the Syr Darya River in 1960–2015, the negative reaction coefficients were calculated for the local population, soil and vegetation for five of the irrigated massifs of the Kyzylorda region. The ecological situation of the habitat of soil and plants in the lower reaches of the Syr Darya River in all irrigation areas deteriorates on a time scale, since as a result of the reclamation of agricultural lands, intensive secondary soil salinization occurs and the formation of infiltration runoff with high mineralization, contributing to the violation of the harmonization of the relationship between nature and man.

Opis:: The progressing urbanization leads to the growth of buildings within the cities and taking up new areas for investments. Uncontrolled urban sprawl entails a number of consequences resulting in the soil sealing of the areas which has been permeable so far. Cutting off deeper soil layers from gas exchange and access to water causes a reduction in biological activity and biodiversity. That is why EU considers soil sealing as one of the main problems of the 21st century. The paper attempts to analyze the progressing urbanization on the one of the Zielona Góra housing estates - Jędrzychów Residential Area.

Opis:: In the result of geomechanical transformations associated with the activity of open cast brown coal mining, some changes in air-water relations may occur on arable land adjacent to these regions usually referred to as hvdrological alterations. However, they do not always need to result in soil degradation, i.e. in the deterioration of their production potentials. This will often depend on the distance of fields from the workings, value of the arable land (soil quality class), type of water management, etc. On the basis of long-term studies carried out in the area of operation of two brown coal mines - KWB "Konin" and "Adamów" - on arable land and grasslands of over 60 villages on the total area of 30 thousand hectares it was possible to develop evaluation criteria for the extent of soil degradation and work out principles for compensation payments for farmers. Three zones and appropriate sub-zones of soil susceptibility to drainage were determined and clear and simple criteria for the estimation of the extent of arable land and grassland degradation were worked out. Furthermore, the authors proposed simple and readable systems to calculate compensatory payments to be paid to farmers taking into account the state of soil degradation, value of agricultural land (price of 1 ha of land of appropriate class) and the area of damaged land. The degree of soil degradation, both of arable land and grasslands, ranged from 10 to 30%. In the case of grasslands, additionally, an appropriate sum of money was allocated to compensate for sward recultivation.
