Opis:
Water erosion in mountainous areas is a major problem, especially on steep slopes exposed to intense precipitation. This paper presents the analysis of the topsoil loss using the SWAT (Soil and Water Assessment Tool) model. The SWAT model is a deterministic catchment model with a daily time step. It was designed to anticipate changes taking place in the catchment area, such as climate change and changes in land use and development, including the quantity and quality of water resources, soil erosion and agricultural production. In addition to hydrological and environmental aspects, the SWAT model is used to address socio-economic and demographic issues, such as water supply and food production. This program is integrated with QGIS software. The results were evaluated using the following statistical coefficients: determination (R2), Nash-Sutcliff model efficiency (NS), and percentage deviation index (PBIAS). An assessment of modelling results was made in terms of their variation according to different land cover scenarios. In the case of the scenario with no change in use, the average annual loss of topsoil (average upland sediment yield) was found to be 14.3 Mg∙ha-1. The maximum upland sediment yield was 94.6 Mg∙ha-1. On the other hand, there is an accumulation of soil material in the lower part of the catchment (in-stream sediment change), on average 13.27 Mg∙ha-1 per year.

Opis:
The article presents the results of monitoring the aftereffect of the use of excessive zonal doses of mineral fertilisers on soil contamination with heavy metals (HM). With traditional soybean cultivation technology, the level of soil contamination when applying excessive doses (N60 P180 K90) of fertilisers is quite high and indicates violations of the ecological balance of the agroecosystem. By the nature of the accumulation of heavy metals in meadow-chestnut soil, depending on the application of the studied doses (P60 K30, N30 P60 K30, N60 P180K90) of fertiliser, the content of HM (Pb, Zn, Cd) increases. The greatest contamination of the soil with Cu was revealed, the content of which increases to 3.2 mg∙kg-1 of soil, which is higher than the threshold of the maximum permissible concentration (MPC) - 3.0 mg∙kg-1. According to the level of contamination of the soil with copper, it belongs to the highly dangerous classes. In a comparative assessment of the level of soil contamination with HM, optimal norms of mineral fertilisers have been established, namely, against the background of effective resource-saving technology for growing soybeans. The application of fertilisers at a dose of P60 K30 and N30 P60 K30 does not significantly affect the level of soil contamination with HM, optimises the ecological state and nutrient regime of the soil, preserves and restores soil fertility indicators, and increases soybean productivity. This resource-saving technology provides a safe environment for soybean cultivation and a significant increase of 34.5-38.6% in crop productivity (0.53-0.76 Mg∙ha-1) and yield (2.57 Mg∙ha-1).

Opis:
Organic wood waste (sawdust, shavings, pieces of wood and bark), is widely used as a secondary raw material and, after composting, for soil fertilisation and substrate production in agriculture, horticulture, forestry, urban landscaping and rehabilitation of degraded land. However, problematic to process is wood waste that is very dirty with soil. They have limited calorific value and cannot be used in the R10 recovery process of land treatment benefiting agriculture or improving the environment. However, the morphological composition of these wastes indicates that they have good properties and can be used for agricultural use and for the reclamation of degraded land. The research involved wood waste with the code 03 01 99 (other unspecified waste from wood processing and the production of panels and furniture) generated during the preparation of deciduous tree logs for the veneer production process, and ashes from the burning of wood waste generated in the veneer production factory. The aim of the study was to assess the chemical composition of these wastes and the possibility of their agricultural use. In the samples of wood waste and ashes there was determined: pH; chlorines content; conductivity; hydrolytic acidity; content of micro and macroelements and heavy metals. The morphological composition of the waste is dominated by sawdust, with a smaller share of shavings, bark and earth parts, and a small addition of pieces of wood of various sizes. It is rich in easily bioavailble as well as total macroelements and is not contaminated with heavy metals. Analyzed wood waste has deacidifying properties, high sorption and buffering capacity. Studies have shown that the wood waste produced at the veneer factory, can be used as an organic fertiliser, a component of other organic fertilisers, for soil mulching, horticultural substrate and soil and land reclamation.The ash obtained from burning wood is strongly alkaline and rich in alkaline cations, mainly Ca, Mg and K. It is not contaminated with heavy metals. The ash can be used for soil deacidification and fertilization, especially for soil reclamation. The waste from the heap can be used as an organic fertilizer, a component of other organic fertilizers, for mulching soils and as a gardening substrate. However, the possibilities for non-agricultural (e.g.: for the production of pallet, particle board) use are limited due to the high proportion of earthy parts.

Opis:
In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3- and 6-wheel passes showed increased bulk density (7–12%), field capacity (9–19%), ridge storage efficiency (35–38%), water use efficiency (16–20.5%) and decreased soil porosity (7–16%), infiltration (8–20%), and furrow storage efficiency (28–41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.

Opis:
The article is devoted to a topical scientific problem in modern conditions – valuation of land in Ukraine. The imperfection of the existing approaches requires further research on the changing conditions of land use and their impact on land pricing. A methodology for determining the market value of reclaimed land based on a differentiated assessment of its productivity through crop yields is proposed, taking into account natural and climatic zones and other conditions of a particular region. The basis of the methodology is the application of long-term forecast and a set of forecast and simulation models, in particular the model of area climatic conditions and the model of water regime and water regulation technologies on reclaimed land. At that the crop yield model as a complex multiplicative type model takes into account all main factors influencing crop yield formation: weather, climatic and soil conditions, cultivation techniques, water regime of reclaimed land, etc. The proposed approaches were tested by the method of large-scale machine experiment using a land plot in the zone of Western Polissya of Ukraine as the example. The obtained results indicate that there is a differentiation in land value, which is a proportional derivative of the yield of cultivated crops depending on the conditions of their cultivation. The variation range of the studied indicators in relative form by the ratio of maximum and minimum values to the weighted average value is for cultivated crops – 393%, and for the above soils – 44.6%. Thus, within one object, the estimated value of land in view of available soils and cultivated crops varies from USD2456∙ha–1 to USD4005 ∙ ha–1, averaging USD3522 ∙ ha–1 .

Opis:
Chemical fertilizer use is highly increasing in farming activity, and the process has a significant impact on soil quality and pH which is the measurement of the acidity or alkalinity. Therefore, soil pH is the main variable because it regulates plant nutrition availability by controlling the chemical forms of various nutrients in agricultural activity. This research aims to find out the excessive use of chemical fertilizers & dynamic soil pH on agricultural land. The primary data had collected by using questionnaires, interviews, Focus Group Discussion (FGD) and soil testing. For the soil testing experiment, simple random sampling method was used to collect the sample in 11 agricultural continents using GPS technology to identify the land location and 22 soil samples were collected based on pre and post applied chemical fertilizer stage. In order to pH value were tested from the collected soil samples. Accordingly, the data were analyzed by ArcGIS 10.3 using the IDW technique. Therefore, the results find out the condition of soil quality during the pre-chemical fertilization, 9% of the land found to be slightly acidic, 27% of the land with neutral soil structure and 15% of the land with salinity soil structure. During the post-chemical fertilization, 9% of the land was found to be moderately acidic, 41% of the soil was found to be strongly acidic, 32% of the soil highly acidic and 18% of the land be moderately pH. The result of the study shown, chemical fertilizers use highly impact on soil quality and agricultural land productivity.

Opis:
The article considers a comprehensive study of the problem of land relations development in the region. It identifies the main directions for their further development, which include improving the legislative framework, economic and monetary valuation of land, leasing land relations and ensuring the formation of a market for agricultural land and ecologically safe land use. The article aims to determine the interrelated components of the organizational and economic mechanism for managing land resources of agricultural enterprises in the context of ensuring land-use efficiency based on the choice of a land-use optimization model. The theoretical and methodological bases for the development of land relations in the conditions of market economy formation are generalized. The directions for improving the ecological status of agricultural land are justified. The state regulation of land relations is analyzed, and ways to improve land legislation are proposed. The directions of the formation and development of the agricultural land market are justified. The ways to improve the ecological condition of the land, taking into account the regional characteristics of the Vinnytsia region, are proposed. To determine the relationship of rational use and reproduction of resources, considering the problems of choosing the optimal strategy for the impact of the economy on the ecologization of land resources, the system of rational use and reproduction of natural resources is developed. The optimization model describing the conditions for the process of stimulating landowners and land users in the direction of protection and rational land use is established.

Opis:
Improving water productivity (WP) through deficit irrigation is crucial in water-scarce areas. To practice deficit irrigation, the optimum level of water deficit that maximizes WP must be investigated. In this study, a field experiment was conducted to examine WP of the three treatments at available soil water depletion percentage (Pi) of 25% (reference), 45% and 65% using a drip irrigation system. Treatments were arranged in a randomized complete block design. The water deficit was allowed throughout the growth stages after transplanting except for the first 15 days of equal amounts of irrigations during the initial growth stage and 20 days enough spring season rainfall during bulb enlargement periods. Physical WP in terms of water use efficiency (WUEf) for treatments T1, T2, and T3 was 9.44 kg∙m–3, 11 kg∙m–3 and 10.6 kg∙m–3 for marketable yields. The WUEf and economic water productivity were significantly improved by T2 and T3. The WUEf difference between T2 and T3 was insignificant. However, T2 can be selected as an optimal irrigation level. Hence, deficit irrigation scheduling is an important approach for maximizing WP in areas where water is the main constraint for crop production. The planting dates should be scheduled such that the peak water requirement periods coincide with the rainy system.

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:
Acid sulfate soils in coastal wetland areas are particularly vulnerable to land-use changes. We identifid the potential impacts of land-use changes in the Can Gio coastal wetland area in Vietnam due to the reclamation of acid sulfate soils from shrimp farms. Our study applied the support of vector machine algorithm in ENVI software to observe land-use changes from 1995 to 2015, using Landsat Thematic Mapper and Operational Land Imager data. We classifid the land use of the study area into four major classes including vegetation, bare land, dedicated land and aquaculture land. Our study successfully met the overall classifiation accuracy requirement above 95% and kappa statistics above 0.95. Between 1995 and 2006, about 2,938.05 ha of bare land and 1,464.66 ha of vegetation (mangrove forest) were converted to aquaculture land. In contrast, between 2006 and 2015, 2,423.88 ha of aquaculture land converted back to bare land, mainly related to the abandonment of shrimp ponds due to crop failure and disease. The disturbance of acid sulfate soils through initial soil reclamation and subsequent fallowing is considered a key reason for hastening and extending soil acidifiation in the study area. We collected 144 topsoil samples from 17 fallowed ponds in two batches, and 142 of these were acidic: 128 samples were extremely and strongly acidic (pH < 5.5), 14 samples were moderately and slightly acid (pH between 5.5 and 6.5), and only two samples were neutral (pH over 6.5).

Opis:
The aims of this study were to evaluate five infiltration models for mineral soils in the tropics with different land use types, such as settlements, plantations, rice fields, and forests. The infiltration models evaluated were Green–Ampt, Kostiakov, Kostiakov–Lewis, Philip, and Horton. The research was conducted at the Amprong watershed, Malang, Indonesia. The infiltration rate of the thirteen soil samples was analysed. The infiltration was tested using Turf-Tech infiltrometer. Moreover, each soil sample was tested in terms of the bulk density, specific gravity, porosity, soil moisture, and soil texture. The results of the study indicate that there is no significant difference (α = 5%) in the infiltration rate among the five models of infiltration. The infiltration rate in the study site was considered fast. Three models exhibiting the best performance are Kostiakov, Kostiakov–Lewis, and Horton model, respectively. The highest infiltration rate occurred in the forest land use while the lowest occurred in the rice field land use. The results of this study suggest that the infiltration model parameters correlate closely with the initial infiltration rate (fo) and the final infiltration rate (fc). In other words there is a correlation between the soil's ability to absorb water (representing the capillary force or horizontal flow) at the beginning of the infiltration (fo) and the gravity or the vertical flow upon reaching the final infiltration rate (fc).
Celem badań prezentowanych w niniejszej pracy była ocena pięciu modeli infiltracji opracowanych dla gleb mineralnych o różnym typie użytkowania w tropikach, takich jak: obszary zabudowane, plantacje, pola ryżowe i lasy. Oceniano modele Greena–Ampta, Kostiakova, Kostiakova–Lewisa, Philipa i Hortona. Badania prowadzono w zlewni Amprong, Malang w Indonezji. Analizowano tempo infiltracji w trzynastu próbkach glebowych z użyciem infiltrometru Turf-Tech. Ponadto w każdej próbce gleby analizowano gęstość objętościową, ciężar właściwy, porowatość, wilgotność gleby i skład granulometryczny. Wyniki badań dowiodły, że nie ma istotnej różnicy w tempie infiltracji (α = 5%) obliczonej za pomocą wymienionych pięciu modeli. Uznano, że tempo infiltracji było duże. Trzy modele, kolejno: Kostiakova, Kostiakova–Lewisa i Hortona okazały się najbardziej odpowiednie. Największe tempo infiltracji stwierdzono w glebach leśnych, a najmniejsze w glebach pod polami ryżowymi. Wyniki badań sugerują, że parametry modelu infiltracji są ściśle skorelowane z początkowym (fo) i końcowym (fc) tempem infiltracji. Innymi słowy, istnieje korelacja między zdolnością gleby do absorbowania wody (reprezentowana przez siły kapilarne i przepływ poziomy) na początku infiltracji (fo) oraz siłą ciążenia i przepływem pionowym po osiągnięciu końcowego tempa infiltracji (fc).

Opis:
Pola irygacyjne Osobowice pełniły przez przeszło 100 lat funkcję naturalnej oczyszczalni ścieków wrocławskiej aglomeracji miejskiej. Obiekt ten położony jest na Równinie Wrocławskiej, w północnej części Wrocławia – pomiędzy korytami dwóch rzek: Odry i Widawy. Początki funkcjonowania oczyszczalni sięgają lat 80. XIX w. – powierzchnia pól irygowanych zajmowała wtedy około 560 ha. Z czasem obszar ten ulegał systematycznemu powiększaniu, prawie do 1300 ha. W związku z uruchomieniem (i modernizacją w 2012 r.) Wrocławskiej Oczyszczalni Ścieków na Janówku, udział pól irygowanych w procesie oczyszczania ścieków ulegał systematycznemu zmniejszaniu – zarówno pod względem ilości ścieków, jak i powierzchni zalewanej. Eksploatację pól zakończono ostatecznie w roku 2013. W znacznej części powierzchni obszar ten stanowi obecnie użytek ekologiczny, w związku z występowaniem na tym obszarze bogatej fauny i flory. W pracy przedstawiono historię obiektu, szczegóły jego funkcjonowania i gospodarki wodnej w trakcie eksploatacji a także obecny stan pól, głównie pod kątem wód gruntowych, które po zakończeniu zasilania tego terenu ściekami obniżyły się wyraźnie na znacznej jego części.
Osobowice irrigation fields served as a natural sewage treatment plant of the Wroclaw urban agglomeration for over 100 years. The object is located on the Wroclaw Plain, in the north part of Wroclaw – between two river beds: Odra and Widawa. The beginning of the exploitation of the fields dates back to the year 1880. The irrigated area, at that time, was about 560 ha. In next years, the fields were systematically expanded almost to 1300 ha. After the Janowek Sewage Treatment Plant start-up (and its modernization in 2012) the share of irrigated fields in the sewage treatment process has been systematically decreased, both in terms of the amount of sewage and the flooded area. The fields exploitation was finished in 2013. A large part of the area, now constitutes the ecological area, due to the occurrence of a rich fauna and flora in this area. The work presents the history of object, details of the facility’s operation and characteristics of water management during its operation, as well as the current state of the fields, mainly in terms of groundwater levels, which – without flooding this area with sewage – have decreased in a significant part of this terrain.

Irrational agricultural activity, deforestation, increasing industrialization and progressive urbanization lead to the loss of important functions of this natural resource. This is a serious problem throughout the European Union, as evidenced by statistical data disclosed in reports of the European Commission. Due to the failure to develop regulations at the EU level ordering the issues of protection of land surface and the fragmentary nature of binding regulations, each of the Member States, including Poland, selected legal means to achieve the assumed objectives related to both the obligation to protect the function of this resource, quality monitoring, registration pollution, or restoring utility and natural values. The aim of the conducted research was to analyze legal regulations establishing administrative law forms of rationing for the use of earth’s surface and their assessment in terms of implementing the principles of sustainable management of this resource. It should be stated that the gradually introduced instruments of land use regulation are not completely used to implement the principle of sustainable land management, although de lege ferenda would have to make an application for ensuring stable, comprehensive and coherent solutions.
Degradacja powierzchni ziemi w różnych formach to jeden z podstawowych i utrzymujących się problemów globalnych. Nieracjonalna działalność rolnicza, deforestacja, coraz większe uprzemysłowienie oraz postępująca urbanizacja prowadzą do utraty ważnych funkcji tego zasobu naturalnego. Jest to poważny problem na terenie całej Unii Europejskiej, o czym świadczą dane statystyczne ujawnione w przywołanych sprawozdaniach i raportach Komisji Europejskiej. Z uwagi na fiasko opracowania regulacji na poziomie UE, porządkującej problematykę ochrony powierzchni ziemi, oraz fragmentaryczność wiążących przepisów każde z państw członkowskich, w tym Polska, dokonało doboru środków prawnych do realizacji zakładanych celów, związanych zarówno z obowiązkiem ochrony funkcji tego zasobu, monitoringu jakości, rejestracji zanieczyszczeń, jak i przywracania wartości użytkowej i przyrodniczej. Celem prowadzonych badań była analiza regulacji prawnych ustanawiających administracyjne formy reglamentacji korzystania z powierzchni ziemi oraz ich ocena dokonana pod kątem implementacji zasad zrównoważonego gospodarowania tym zasobem. Reasumując, należy stwierdzić, że wprowadzane stopniowo instrumenty reglamentacji korzystania z powierzchni ziemi nie do końca służą wdrożeniu zasady zrównoważonego gospodarowania powierzchnią ziemi, chociaż de lege ferenda należałoby wnioskować o zapewnienie stabilności, kompleksowości i spójności wprowadzanych rozwiązań.

Opis:
In the context of climate change, issues on more rational use of water resources and hydrological extreme events, such as floods, causing numerous negative effects every year, are becoming more acute. In small hydrographical basins, like the hydrographical basin of the Sebeş River (Romania), floods and their destructive effects have been and are amplified by the massive deforestation and the improper exploitation of surfaces. The analysis of the physical and geographical features of Sebeș hydrographical basin enables us to establish the runoff regime, including for the periods with high waters and floods. The maximum runoff occurring in this representative and experimental hydrographical basin was calculated based on the input data processed in GIS. The calculation equation to determine the maximum runoff of this small hydrographical basin used the physical and geographical features of the basin, namely: the relief altitude, the slope, the land use cover, the soil types, the rain intensity and their features. From the analysis of the runoff spatial distribution within Sebeş hydrological basin, we may notice that various geomorphometric components have a higher or lower share in determining the runoff coefficient.
W kontekście zmian klimatycznych coraz poważniejsze stają się kwestie bardziej racjonalnego wykorzystywania zasobów wodnych i ekstremalnych zdarzeń hydrologicznych, takich jak powodzie, powodujące liczne negatywne skutki każdego roku. W małych dorzeczach hydrograficznych, takich jak dorzecze rzeki Sebeş (Rumunia), powodzie i ich destrukcyjne skutki zostały wzmocnione przez masowe wylesianie i niewłaściwe zagospodarowanie terenu. Analiza fizycznych i geograficznych cech dorzecza Sebeş pozwala ustalić reżim odpływu, także dla okresów o wysokim stanie wody i powodzi. Maksymalny odpływ występujący w tym reprezentatywnym i eksperymentalnym dorzeczu hydrograficznym został obliczony na podstawie danych wejściowych przetworzonych w GIS. Równanie obliczeniowe maksymalnego odpływu z badanego małego dorzecza wykorzystuje fizyczne i geograficzne cechy dorzecza, a mianowicie: wysokość wypiętrzenia, nachylenie, pokrycie terenu, typ gleby, intensywność opadów i ich cechy. Na podstawie analizy rozkładu przestrzennego odpływu w obrębie dorzecza Sebeş można zauważyć, że różne składniki geomorfometryczne mają większy lub mniejszy udział w określaniu współczynnika spływu.
