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:
Ukształtowanie rzeźby terenu ma podstawowy wpływ na zjawiska przyrodnicze zachodzące na powierzchni Ziemi. Dyrektywa 2000/60/WE (Ramowa Dyrektywa Wodna) Parlamentu Europejskiego i Rady Europy (23.10.2000) nakazuje wprowadzenie obowiązku zrównoważonego gospodarowania zasobami wody, między innymi poprzez ochronę przed pogarszaniem się stanu wód, ekosystemów wodnych oraz ekosystemów lądowych i terenów podmokłych zależnych od wody. Geneza powstania terenów podmokłych oraz zbiorników naturalnych wody związana ze strukturą i typem gleb, ukształtowaniem terenu, ze spływem powierzchniowym wód w cyklu hydrologicznym oraz z wodami podziemnymi, które przy pochyłej warstwie nieprzepuszczalnej występują w postaci strumienia płynącej wody, znajdującej ujście w postaci źródeł lub sap. Ukształtowanie terenu jest funkcją grawitacyjnego zniesienia stokowego gleby będącego gęsto-plastycznym biegiem złoża powierzchownego po powierzchni nachylonej opisywanym równaniem Szwedowa-Binghama. Ruch gleby na skosach ustaje po osiągnięciu nachylenia końcowego. Stanem końcowym będzie profil H = H0, na którym krusz już jest w warunkach stabilności. W miarę upływu czasu kształt profilu dowolnego zbocza stanie się regularny niezależne od jego stanu pierwotnego, przy czym w jego dolnej części uformuje się strefa akumulacji kruszy, która przy określonych warunkach hydrologicznych i glebowych stanowić będzie naturalną zaporę wód powierzchniowych i zaskórnych. Celem prowadzenia badań było opracowanie metod oceny stabilności ukształtowania terenu z wykorzystaniem nowoczesnych metod fotogrametrycznych i geoinformacyjnych oraz pozyskiwania obszarów zagrożonych podtopieniem i zanieczyszczeniami związanymi z powierzchniowymi oraz gruntowymi spływami wód.
Landscaping has a major impact on the natural phenomena that occur on the surface of the Earth. Directive 2000/60/EC of the European Parliament and of the Council of Europe (23/10/2000) prescribes an obligation of sustainable management of water resources, including by protecting them against deterioration of water, aquatic and terrestrial ecosystems and wetlands dependent on water. Origins of wetlands and natural water reservoirs associated with the structure and the type of soil, topography, the surface flow of water in the hydrological cycle and the groundwater that emanates as a stream water under sloping impermeable layer. The Szwedow-Birghman equation describes the function of gravity relating flow of terrain which is density-plastic soil on slope surface. The movement of soil on sloping angle stops after reaching the final state. The final state will profile H = H0 that shows the terrain in stability condition. Over time, the shape of any profile will become regular independent of its original condition, and in its lower part forms a zone of accumulation, which under certain conditions, hydrological and soil will be a natural barrier for surface and underground water. The aim of this study was to develop methods to assess the stability of the terrain using modern methods of photogrammetry and geospatial and gain areas at risk of flooding acquisition and pollution associated with the flow of surface water and groundwater.

Opis:
Sediments are the major source of pollution in surface waters of the Pacific Northwest Region of the USA. The purpose of this study is to evaluate the relationship between SMI water quality scores at 76 sampling sites in eight watersheds and the observed soil erosion rates on adjacent landscapes. The water quality SMI scores in streams were obtained using stream macro invertebrates as an indicator of water quality, while soil erosion rates were determined by observation on adjoining landscapes during periods of maximum precipitation. Soil erosion rates of <2, 2–5, 5–15, 15–25 and >25 mt/ha/yr were observed at 9, 20, 45, 14 and 12% of the sampling sites, respectively. Landscapes with erosion rates of less than 5 mt/ha/yr generally resulted in good water quality in adjacent streams; however, when soil erosion rates on adjacent landscapes exceeded 5 mt/ha/yr SMI water quality scores were less than good 86% of the time. Strong signifi cant relationships were observed between SMI water quality rating and observed soil erosion rates. Consequently, land management or rehabilitation practices that reduce soil erosion rates to levels below 5 mt/ha/ /yr should improve stream water quality.
Rumowisko rzeczne stanowi główne źródło zanieczyszczenia wód powierzchniowych w zlewniach Pacyfiku w północno-zachodnim regionie USA. W pracy przedstawiono wyniki badań prowadzonych w ośmiu zlewniach w celu określenia zależności między indeksem jakości wody SMI w 76 przekrojach kontrolnych a wartościami wskaźnika erozji gleb na przyległych obszarach. Jako wskaźnik jakości wody do określenia wartość SMI wykorzystano badania makro bezkręgowców wodnych, natomiast wskaźnik erozji gleb określano na podstawie obserwacji terenu w okresach maksymalnych opadów deszczu. Uzyskano silną zależność między wartościami SMI a wartościami wskaźnika erozji gleb. Stwierdzono, że gdy wskaźnik erozji gleb przekraczał wartość 5 mt/ha/rok wówczas w 86% okresu obserwacji jakość wody była gorsza od dobrej, tj. słaba, zła lub bardzo zła. Zagospodarowanie terenu oraz działania w celu redukcji wartości wskaźnika erozji gleb poniżej 5 mt/ha/rok powinno poprawić jakość wody w ciekach.

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:
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:
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 .

Определения выбранных физических свойств почвы проводились на песчаной почве содержащей 9,9% илистых частиц в период с мая по август. Образцы отбирали из почвы многолетней залежи и черного пара, а также из почвы поля кратко - и долговременного севооборота. Установлено, что в сравнении с почвой полей севооборота длительное удерживание почвы в черном паре приводило к снижению, а удерживание в состоянии залежи к повышению водостойкости почвенных агрегатов. В условиях залежи порозность почвы удерживалась на высшем, а плотность и влажность почвы на более низком уровне, чем почвы полей севооборота и черного пара. Со значениями указанных свойств коррелировали, в общем, значения характерные для плотности почвы.
The selected physical properties of the site were determined on sandy soil containing 9.9% of clay and silt particles in the period from May to August. The samples were taken from the soil unused for many years and from black fallow as well as from the field of short- and long-term crop rotation. It has been found that the prolonged maintenance of soil in the black fallow led to a decrease and in the many-year unused soil - to increase of waterproofness of the soil aggregates. Under the fallow conditions the soil porosity maintained at a higher and its compactness and moisture - at a lower level than on crop rotation fields and black fallow. With the above values the values characterizing the soil compaction were usually correlated.

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:
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:
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).
