Opis:
Soil environment, both biotic (e.g., microbial community) and abiotic (e.g., nutrients and water availability) factors determine soil fertility and health and are directly affected by soil management systems. However, only limited studies evaluate the combined effect of nutrients availability and soil disturbance on the soil bacteria community structure, especially in conventional agricultural practices, on the forests converted to agricultural land. This study aimed to provide a viewpoint of the effect of different soil management systems, i.e., forest soil (natural process) and tilled land, on soil bacteria community structure on forest converted to agricultural land, according to a metagenomics approach. Moreover, each land use was sampled to identify the bacterial community using 16S gene as a biomarker. The sequencing was performed using MinION (Oxford Nanopore Technologies) to read the DNA sequence from each soil sample. Principle Component Analysis (PCA) was performed to comprehend the relationship between availability of nutrients and bacterial diversity. The results revealed that the concentrations of soil micronutrients, such as iron, zinc, and magnesium, were significantly higher in forest soil than in tilled land. According to diversity indices, soil bacteria were more diverse in forest soil than in tilled land. Forest soil had more distinctive taxa than tilled land. Several species comprised the most abundant taxa, such as Candidatus Koribacter versatilis, Candidatus Solibacter usiatus, Rhodoplanes sp., Luteitalea pratensis, and Betaproteobacteria bacterium, were more scarce in tilled land. On the distinctive taxa in each soil sample, Anseongella ginsenosidimutans and Janthinobacterium sp. were the most abundant species in forest and tilled land, respectively. According to PCA analysis, soil management system affected the soil micro-and macronutrients also microbial community structure between forest and tilled land. In conclusion, soil management influences the essential nutrient content and bacterial community structure of soil. Better management should be adopted to maintain soil quality near forest soil.

Opis:
Celem pracy było określenie wpływu siedliska leśnego na zróżnicowanie jakościowe substancji humusowych w poziomach próchnic nadkładowych gleb leśnych tworzących się w pobliżu starodrzewu Quercus robur (200 – 600 lat). Analizowane gleby były zlokalizowane na terenie obszaru chronionego krajobrazu – w Borach Niemodlińskich i Lasach Stobrawsko-Turawskich. Badane gleby reprezentowały 15 profili zaliczanych do bielic, gleb brunatnych właściwych i kwaśnych. Specyfika i troficzność siedliska leśnego wpłynęły na ukształtowanie właściwości fizykochemicznych i chemicznych analizowanych gleb leśnych, co wyrażało się przede wszystkim w ich kwaśnym odczynie, zróżnicowanym zasoleniu jak i właściwościach optycznych substancji humusowych. Jednocześnie stwierdzono ilościowe zróżnicowanie materii organicznej w analizowanych poziomach gleb wyrażone wartością współczynnika zmienności (V) równą 61%. Uzyskane wyniki analiz chemicznych i wartości indeksów A2/4, A2/6, A4/6, ΔlogK oraz współczynników korelacji wskazują, iż w badanych glebach procesy transformacji materii organicznej prowadzą do wytworzenia substancji humusowych o niskim stopniu humifikacji i ilościowym zróżnicowaniu w profilach. Zmienność analizowanych właściwości charakteryzujących jakość substancji humusowych wskazuje, iż transformacja materii organicznej poziomów ektohumusowych zależy w dużym stopniu od jakości siedliska, w tym od rodzaju dopływającej materii organicznej.
The aim of this work was to determine the diversity of qualitative humic substances in the ectohumus horizon of the forest soil profiles. The analyzed soils were located in protected landscape areas and nature parks – Bory Niemodlińskie and Lasy Stobrawsko-Turawskie, and occurred under the tree stands of trees which were 200 – 600 years old – Quercus robur. The analyzed soils represent 15 soil profiles belonging to Podzols, Cambisols and Dystric Cambisols. Properties of forest habitat specificity influenced the physicochemical and chemical properties of the analyzed soils. We observed particularly strong expressions of acidity, pH and salinity, and a diversity of chemical and optical properties of humic substances. The content of organic matter in the analyzed soil horizons showed considerable variation, as indicated by a coefficient of variation (V) equal to 61%. The composition of humic substances of forest litter is characterized by a gradual change of functional groups that usually consists in the decrease of carbohydrates, the relative increase of carboxyl and alkyl carbon, and decay of lignin. In the investigated soils, we observed that the transformation processes of organic matter led to humic substances which were predominantly humus with a lower level of humification, as evidenced by the indexes: A2/4, A2/6, A4/6, ΔlogK. Therefore, variation of the observed properties of humic substances indicates a different direction in the transformation process of organic matter. Such a transformation depends very much on the habitat and nature of supplied organic matter.

Opis:
Podstawowym sposobem ograniczania erozji gleb i gruntów jest zmiana ich użytkowania, na przykład z ornego na leśne. Szczególnie skuteczną funkcję ochronną pełnią – zgodnie z przyjętą w Polsce formułą prawną – lasy glebochronne. W pracy określono różnice w deformacji podstawowych właściwości gleb na powierzchniach stokowych w zależności od sposobu ich użytkowania oraz oceniono rolę lasów glebochronnych w ograniczaniu natężenia i skutków procesów erozyjnych. Wykonane przekroje niwelacyjno-glebowe oraz analizy pobranego z odkrywek materiału wykazały, że lasy glebochronne stanowią istotną ochronę przed degradacją pokrywy glebowej, ograniczając m.in. ubytki próchnicy oraz redukcję wierzchnich poziomów i warstw pedonów. Na stokach pod lasami glebochronnymi stwierdzono wyraźne zmiany uziarnienia i właściwości chemicznych gleb w stosunku do sąsiadujących z nimi stoków użytkowanych rolniczo.
The basic method of reducing soil and land erosion is a change of land use, for example, from arable to forest. Particularly effective as a protective role – according to the Polish law – soil-protecting forests. The thesis presents differences in the deformation of the basic soil properties on moraine slopes, depending on land use. There has been presented the function and the efficiency of the soil-protecting forests in erosion control. The soil cross section transects and soil analysis displayed that soil-protecting forests are making an essential soil cover protection from degradation, inter alia, limiting the decrease of humus content, reduction of upper soil horizons and soil pedons layer. On the afforested slopes it was stated some clear changes of grain size and chemical properties of soils in relation to adjacent slopes agriculturally used.

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:
Fires in natural ecosystems have a detrimental effect on all biota components. In the global scale, many scientific studies of prominent scientists are devoted to this topic. It should be noted that scientists have always been interested in the influence of thermal destruction of soil genetic horizons on the specific activity of radionuclides. Most of these studies began after the Chernobyl (1986) and Fukushima (2011) radiation disasters. The conducted research is focused on the specific activity of radionuclides due to the thermal effects of fires in natural ecosystems. It has been established that the edaphotopes affected by fires are naturally restored causing the restoration of soil formation processes. The specific activity of radionuclides decreases with the duration of the ground fire. Comparing the obtained data with the regulatory documentation, it was found that they do not exceed the minimum significant activity of radionuclides in the workplace. However, the increased activity of radionuclides in soils has a detrimental effect on the ecological condition and flora and fauna development. During the fire season in natural ecosystems and forests, careless handling of fire should be avoided and preventive measures should be taken to inform the public about the harmful effects of wildfire.

Opis:
In the years 2008-2011, the study on the surface and subsurface water runoff from the forested loess slope was carried out to determine the concentrations of selected chemical indicators of water quality, soil suspension and loss of the pure matter component. The maximum tested concentrations of water quality indicators were low and amounted to: 1.841 mg‧dm-3 N-Nog, 0.943 mg‧dm-3 N-NH4, 0.478 mg‧dm-3 N-NO3, 0.213 mg‧dm-3 N-NO2, 0.423 mg‧dm-3 P, 1.621 mg‧dm-3 K. The masses of the eroded matter constituents were low and amounted to: 0.808 kg‧ha-1 N, 0.157 kg‧ha-1 P, 0.142 kg‧ha-1 K and 2.989 kg‧ha-1 soil. The parameters of erosive precipitation and water outflow were statistically significantly correlated with the concentration of soil suspended matter and losses of the analyzed components of matter, as well as negligible concentration of chemical indicators of water quality. Afforestation of the loess slopes threatened by erosion is a treatment that effectively protects the soil against water erosion.

Opis:
This article discusses the ways of solving the problems of fruiting and increasing the yields, as well as obtaining high-quality standard seeds from promising seed plants of black saksaul (Haloxylon aphyllum (Minkw.) Iljin). It presents the results of studying the effect of irrigation and the use of fertilizers on the annual growth of the apical shoots of saksaul, and the effect of irrigation on the further stability of seed plants fruiting for sustainable seed supply for reproduction of saksaul deserts and forest amelioration of deserts. The morphological description of the soil by profiles has been given, and the effect of irrigation on the soils of the type II forest conditions has been described. This study was aimed at resolving the problem of fruiting frequency, increasing the yield and quality of promising black saksaul seed plants by determining the moisture dynamics in the one-meter thick soil layer under saksaul specimens for determining the methods, norms, and time of irrigating seed plants. Long-term observations show that well-developed specimens of black saksaul have appeared in the last 15-20 years on the roadside in some settlements, e.g., Bakbakty, Bakanas, Akkol, Koktal, Karoy, the motor road in village Kanshengel, Topar, Araltobe, Akzhar in the Almaty area, which passes through natural saksaul plantings and the soil with the formation of layered clay, sandy loam, and crushed stone. On the one hand, this was promoted by the presence of layered and well-aerated roadsides of the bulk roadbed, and on the other hand, by additional wetting from the runoff of precipitation from the asphalt pavement.Naturally, these saksaul plantings growing along the roads alone or in rows give a good yield when fruiting; seed plants may also be identified in these groups.

Opis:
Several studies on the assessment of soil organic carbon (SOC) stocks have been carried out at the global level. However, reliable information on SOC stocks is not readily available at the regional level. In addition, very few studies have assessed the factors responsible for the variation of SOC stocks, in particular the effect of plant communities. For this purpose, the main objective was to analyze the effects of three plant communities and ecological parameters on the SOC stock in the Mamora forest. Specifically, the authors looked to examine the relationships between SOC stock and plant communities and to define the main parameters that directly influence SOC stock. Ten soil profiles with three replications were sampled at each plant community, from which SOC stock was determined. To assess the effect of plant communities on SOC stocks, phytosociological surveys were carried out according to the phytosociological stigma method developed by Braun-Blanquet. The results show that the SOC stocks in cork oak soils are characterized by high variability, with values ranging from 55 t•ha-1 to 95 t•ha-1. Indeed, the findings of this study showed that the SOC stocks fluctuated significantly with plant communities. In addition, SOC stocks were also affected by the interactions between plant communities, the amount of litter and the density of the cork oak stand. These outcomes of this study highlight the critical need to incorporate community-specific carbon values into future carbon sequestration modeling.

Rekultywacja gleb po pożarze jest procesem długotrwałym. O jej skuteczności decyduje stopień degradacji gleby, rodzaj wprowadzanych zabiegów, a także typ siedliska. Celem badań była analiza zmian odczynu gleby, zawartości węgla, azotu i fosforu pod wpływem dodatku liści trzech gatunków drzew do rekultywowanych po pożarze gleb leśnych. Badania prowadzono w dwuletnim cyklu w siedlisku boru suchego i świeżego. Ustalono, że spośród wprowadzonych do gleby liści najszybciej rozkładają się liście brzozy brodawkowatej i robinii akacjowej. Procesy dekompozycji wprowadzonej materii organicznej wolniej zachodzą w siedlisku boru suchego niż świeżego.
Reclaiming land after a wildfire is a long-lasting process. Its effectiveness depends on the degree of soil degradation, reclamation measures and the type of habitat. The aim of the study was to analyse the changes in the reaction of soil and the contents of carbon, nitrogen and phosphorus after adding the leaves of three tree species to soil undergoing reclaiming process. The studies were carried out for two years in two habitats: fresh and dry coniferous forests. Verrucose birch and black locust leaves decomposed faster than mountain ash leaves. Organic matter decomposition is generally faster in moist areas of fresh coniferous forests than in dry ones.
