Opis:: The Agricultural Payments Agency (supervisory and registry authority) of the Slovak Republic has announced an erosion hazard layer to meet the requirements of GAEC5 (Minimising soil erosion. Limit soil erosion by putting in place suitable practical measures). If a farmer fails to observe the layer data, they will be fined and might lose access to direct subsidies (also known as direct payments). The layer that has been announced raises a number of questions and concerns amongst beneficiaries of direct subsidies and users of land parcels. For instance, with the Pastuchov land parcel, the uncertainties associated with the application of GAEC5 were raised. A comparison of the water erosion layer commitment for 2023 with the erosion calculated by the Universal Soil Loss Equation (USLE) method based on the Digital Relief Model (DRM) generated from airborne laser scanning has confirmed the uniformity in all classified categories of water erosion over a 65% land parcel area. The situation of the land user has been diminished (i.e. they have to comply with GAEC5 even when there is no reason to) over 11% of the area. The situation of the land user has improved over 24% of the area (i.e. they do not have to comply with the conditions even when there is reason to). This paper describes the problems and outlines the possibilities for the necessary adjustment of compliance with the GAEC5 conditions in Slovakia.

water erosion
Opis:: The control of water erosion is an important economic and societal challenge. Reduction of the agronomic potential of the parcels, muddy flows, siltation of dams are harmful consequences that mobilize farmers, water managers, local authorities and scientific researchers. This study focuses on mapping and quantifying seasonal soil losses in the territory of the former Nord-Pas-de-Calais administrative region, using the Revised Universal Soil Loss Equation (RUSLE) which incorporates five factors: rainfall erosivity, soil erodibility, topography, land use and erosion control practices. The seasonal (3-months) time scale is chosen to better account for the parameters governing the soil water erosion, especially rainfall and vegetation cover, that show great asynchronous intra-annual variability. Also, high resolution data concerning agricultural plots allows to evaluate which type of culture are the more subject to soil losses. In Nord-Pas-de-Calais, water erosion occurs almost ubiquitously, but the areas characterized by steep slopes are the most at risk (Artois Hills and Flanders), with loss rates up to 54 t∙ha-1∙y-1. The majority of erosion occurs during fall (46% of the computed annual losses of 1.69∙Mt), on plots left bare after harvest (especially corn and beets crops). The study also demonstrates that extending the intercrop technique over the region, and therefore maintaining a fall and winter cover, could reduce the soil losses by 37%.

Opis:: Soil erosion is an important factor that should be considered when planning renewable natural resource projects, effects of which can be measured by modelling techniques. Therefore, disintegration models determine soil loss intensity and support soil conservation practices. This study estimates soil loss rates by water erosion using the Erosion Potential Method (EPM) in the Kebir Rhumel Watershed located in Northeast Algeria. The area is north to south sub-humid to semi-arid, receives irregular rainfall, and has steep slopes and low vegetation cover which makes it very vulnerable to erosion. The main factors in the EPM (soil erodibility, soil protection, slope, temperature, and rainfall) were evaluated using the Geographical Information System (GIS) and data provided by remote sensing technologies. The erosion intensity coefficient Z was 0.60, which indicates medium erosion intensity. While the results showed the average annual soil erosion of 17.92 Mg∙ha-1∙y -1, maximum and minimum losses are 190.50 Mg∙ha-1∙y-1 and 0.21 Mg∙ha-1∙y-1, respectively. The EPM model shows satisfactory results compared to some studies done in the basin, where the obtained results can be used for more appropriate management of land and water resources, sustainable planning, and environmental protection.

Opis:: Water and wind erosion are the most powerful factors in the decrease of soil fertility and a threat to food security. The study was conducted on the steppe zone in Ukraine (total area of 167.4 thous. km2), including agricultural land (131.6 thous. km2). At the first stage, the modeling of spatial differentiation of water and wind erosion manifestations was carried out to calculate losses of soil (Mg∙ha–1) and to determine their degradation. At the second stage, soil-climatic bonitet of zonal soils (points) is carried out to determine their natural fertility (Mg∙ha–1). At the third stage, the spatial adjustment of the natural soil fertility to the negative effect of erosion was carried out. This made it possible to calculate crop losses and total financial losses due to water and wind erosion. The integrated spatial modeling showed that about 68.7% of arable land was constantly affected by the combined erosion, in particular the area of low eroded arable land (16.8%), and medium and highly eroded land (22.1%). Due to erodibility of soil, about 23.3% of agricultural land transferred from the category of high and medium quality to medium, low and very low quality, which is caused by the loss of soil fertility of up to 70%, crop losses of up to 1.93 Mg∙ha–1 ha–1 and eduction of agricultural income up to 390 USD∙ha–1. In the steppe region under the research, gross crop losses from erosion were up to 15.11 thous. Mg∙ha–1 (3.05 mln USD). In order to protect soils, improve fertility and increase crop yields in the steppe zone in Ukraine, the following measures were suggested: adaptive and landscape erosion control design with elements of conservation farming in accordance with the spatial differentiation of soil quality and extent of water erosion deflation danger.

Opis:: The paper presents the ecological effects of land consolidation carried out in upland loess areas. The design of a large plot of land on a slope with a gradient of up to 18% and its impact on the intensity of water erosion were investigated. The analyzed plot was created by consolidation 12 smaller plots. Before the consolidation, all plots had a cross-slope layout and direction of agrotechnical operations. Exactly the same arrangement remained after the consolidation. The WEPP simulation model was used for the comparison of the pre-consolidation and postconsolidation state. The amount of soil loss and sediment yield was estimated under different scenarios of slope management. It was found that after consolidation (creation of a plot with the width of more than 130 m), as a result of removing of terraces and sodded cross-slope scarps, the intensity of erosion increased many times. In order to restore the anti-erosion effect of cross-slope cultivation on such a slope without increasing the difficulties of agrotechnics, it is necessary to restore the sodded scarps that existed before consolidation. The simulation results show that the scarps should be located transversely to the slope (along the plot) in the middle and lower parts of the slope, in the place of the highest inclination. As advantage of the consolidation project was considered the elimination of longitudinal balks which were focuses of linear erosion on the slope.

Opis:: Over the past half-century, an expansion of agriculture on lands is observed, followed with increased intensification through larger fields of monoculture crops and application of high level of inputs, that icreases the pressures agriculture sets upon the environment. Raising awareness of consumers and environmentalists led to the promotion of several alternative farming practices, including integrated food and non-food systems (IFNS). Here we explore the potential of different kinds of IFNS systems in delivering environmental benefits, focusing on preserving soil functions as the form of land use limiting the loos of soil by water erosion. Six successfully implemented IFNS systems located in UK, Poland, Italy, Denmark and Romania, were taken as a baseline to investigate their potential impact onto lowering soil loss by water erosion in their respective NUTS3 regions, when they would be applied widely on a regional scale. The results of analyses performed within GIS systems based upon European datasets revealed, that altogether the highest potential of limiting the area of soil erosion exceeding 0,5 Mg ha-1y-1 by an IFNS existing in a particular NUTS is observed in Romania, where 531km2 may be protected effectively with exiting silvopastoral system, while applied in a longer term on non-pastoral land cover classes it could provide effective protection for another 1362 km2. Second largest influence can be achieved in Polish NUTS region, where 125 km2 may be taken into protection directly and an another 1140 km2 may be transformed into agroforestry systems to lower the risk of soil erosion by water. In all investigated regions, a wide introduction of IFNS, that are already proven to be economically successful, would decrease soil loss considerably on existing land cover classes similar to IFNS systems covering 4927km2, while potentially on all agricultural land up to 8854km2.

Opis:: Soil erosion by water is one of the most important factors affecting contemporary landscape changes within the lowland geoecosystems in Central Europe. Soil erosion by water mainly depends on: rainfalls (especially its intensity and erosivity), length of slope and its inclination, type of cultivation and usage of land, anti-erosion treatments and susceptibility of soils to erosion. The aim of conducted research was to evaluate conditioning and magnitude of secular and extreme soil erosion processes in the Drawsko Lakeland with special considering of rainfall erosivity index (EI30). The main goal was realised through several research tasks. The first task involved examination of surface runoff and slope wash conditionings, course and quantity in the testing plot located within the Chwalimski Potok catchment. The second task was related to evaluate rainfall impact to soil erosion by water processes. It was realised by computation rainfall characteristics: intensity, kinetic energy and erosivity. In order to assess secular and extreme soil erosion impact to land relief changes, research were provided with additional details by conducting three field experiments with simulated rainfall. Stationary observation and quantitative researches of soil erosion (at testing plots) have been conducting within the Chwalimski Brook catchment for three hydrological years (2012–2014). The slope with the test area is located within the 1st order catchment being a subsystem of the Młynski Brook catchment and then followed by the upper Parsęta catchment. This area covers 4.8 hectares and is characterised by short slopes with small height variances up to 10 meters. Historically, the area was covered with agricultural crops, currently they cover about 10% of the area. The slope is covered with gleyic retisols and its average inclination is about 4 degrees with its south-east exposure. The measuring system of soil erosion covered 5 testing plots with different agricultural use (bare fallow, meadow, potatoes, spring and winter crops). Plots are 42 metres long and 4 metres width. In the bottom edge of each plot catchers with volume of 800 dm3 were installed. In this research, only data from black fallow were considered. Such tillage is recognised as a standard in soil erosion studies. Two experiments have been conducted in this testing plot. The third one has been conducted on slope located within an area of undulated morainic plateau in the Kłuda catchment. The slope is characterised by greater height variances than in Chwalimski Brook catchment. The slope, where the experiment has been conducted, is situated within local closed depression and is covered by sands underlain by boulder clay. Its average slope is about 10° with its southwest exposure. Although annual precipitation in the three-year measurement period was comparable with mean value from multi-year period (1987–2014), its intensity and erosivity were distinguishably lower. Such rainfall conditions are not favourable for extreme soil erosion by water processes, thus any relief forms from such geomorphological processes were not observed in the Drawsko Lakeland. Due to lack of that kind of forms, in 2013 and 2014, three field experiments were conducted. The main aim of experiments was to evaluate the impact of high intensity rainfall on soil surface. The first experiment consisted of 5, the second and the third of 4 rainfall simulations. The rainfall was created by using a purpose-built rain simulator, consisting of 3 and 6 sprinklers placed around the testing plot. Despite the slope inclination in the Kłuda catchment was 2.5 times steeper than Chwalimski Potok’s slope, surface runoff attained smaller volume, because of remarkably higher infiltration rate. In 2012–2014, surface runoff and soil loss has occurred 8 times each year. The maximal monthly surface runoff volume was registered in February 2012, and it equalled 10.1 dm3 m−2 and the maximal soil loss value was registered in May 2013 and equalled 3,198 kg ha−1. Annual runoff volumes were between 31.2 dm3 m−2 in 2012 and 38.8 dm3 m−2 in 2013, whereas annual soil loss values ranged from 740 kg ha−1 in 2012 to 5,700 kg ha−1 in 2013. Soil erosion values caused by simulated rainfall during field experiments were similar or significantly higher than annual values. Surface runoff was between 31.2 dm3 m−2 in the first experiment and 34.2 dm3 m−2 in the second one, whilst soil loss was between 4,632 kg ha−1 and 8,637 kg ha−1. The achieved experiment results have been compared with soil erosion rate achieved from stationary observations. The results show that runoff and soil loss considerably increase during rainfalls with high amount, intensity and erosivity. Furthermore, individual extreme erosive events may exceed annual (secular) soil erosion processes. Conducted stationary research indicates that annual soil erosion primarily depends on individual rainfall and erosive events, which considerably exceed mean values. In order to evaluate the soil susceptibility to erosion by water in the Drawsko Lakeland, high resolution potential and actual soil erosion risk maps were prepared. The qualitative assessment of soil erosion risk was based on geoinformation technologies. The model considers following conditions affecting the size of soil erosion: slope steepness and aspect, topographic factor LS (unit upslope contributing area), lithology, rainfall erosivity (Modified Fournier Index calculated from monthly and annual precipitation data) and land use and land cover from Corine Land Cover 2006. To prepare the map of potential soil erosion risk, land use from Corine Land Cover was not considered. Thematic maps have been reclassified into a 4-degree division. The results of the soil erosion risk assessment in the Drawsko Lakeland reveal the fact that a majority of its area is characterized by moderate or low erosion risk levels. Areas with high erosion risk are mostly located in the northern part of the Lakeland. The achieved results from stationary observations and field experiments may indicate that the soil loss magnitude significantly increases during rainfall with higher intensity, greater totals and accumulated in time rainfall events. This may confirm the high potential of soil erosion by water processes of above- -average magnitude and intensity in the discharge of material from agricultural used slopes.

Opis:: Spatial raster distribution models of the values of factors influencing the potential soil erosion hazard were created using GIS technologies. The erosion hazard was estimated using the modified RUSLE (Revised Universal Soil Loss Equation) model. The potential of annual soil loss of arable land was calculated. The spatial gradation of erosion violation of administrative and territorial units in the steppe zone of Ukraine was provided. About 32.7% of arable land that is subject to high erosion hazard was allocated. About 48 administrative and territorial units have a specific area less than 5% of erosion disturbed lands. They are characterized by a resistant type of agrolandscapes regarding the water-erosion processes. Most administrative and territorial units with high erosive-accumulative potential (the percentage of the area is 15% or more) are located in the western and southwestern parts of the steppe zone of Ukraine. The specific area of erosion hazardous lands reaches up to 32% in separate administrative-territorial units. The obtained results allow determining the need for a spatially discrete-distribution implementation of adaptive-landscape anti-erosion design with the elements of soil-protective agriculture.

Opis:: The work presents the results of research on erosion and landform changes of a bottom of a dry erosive-accumulation valley in Elizówka in 1958, 1970 and 2016. The changes have been examined with the use of geodetic topographic surveys techniques. The research field was a 480-metres long part of the valley bottom. The topographic surveys in 1958 and 1970 were conducted with longitudinal (parallel to the bottom of the valley) and cross (every 20 metres) sections method. In 2016 the modern measuring devices were used. All the results, together with coordinates of points and historical data were converted into GIS spatial layer. The altitude values formed the input data for interpolation of rasters showing changes of the topography in three periods. Three TIN models were also developed to distinguish erosion and accumulation zones plus the quantity of eroded and accumulated material. The valley on the majority of its length has been raised and has changed from V-shaped into U-shaped. Accumulation of the soil material led to levelling the bottom. Accumulation concentrates along a flow line, while soil washout mainly at the bottom of slopes. The thickest sediment layers were observed in the lowest part. For the whole 1958–2016 period a total of 3470 m³ soil material has been deposited on the area of about 1.62 ha, while in the same time only 130 m³ has been eroded (from 0.22 ha).

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.

Low hills are typical in the morphology of the area. Results presented come from measurements of soil erosion by water in 2007–2009. Soil erosion took place during short transformation periods and was caused by events of high magnitude and low frequency during which soil particles are transported from the slope to the channel, but its supply was only local and episodic. In the foothill area slope and channel are weakly linked.

Opis:: Przedstawiono wpływ uprawy roli na gospodarkę wodną gleby, która decyduje o plonowaniu roślin, przy ekstremalnych zjawiskach pogodowych - okresowych suszach lub intensywnych opadach. Omówiono pogorszenie stanu gleby i obiegu wody w glebie wskutek niewłaściwej uprawy i innych prac polowych. Przedstawiono techniczne i technologiczne środki zaradcze, poprawiające zdolność gleby do infiltracji, retencji i udostępniania wody roślinom. W podsumowaniu stwierdzono, że działania poprawiające gospodarkę wodną gleby są możliwe w każdym systemie uprawy roli, a szczególnych działań ochronnych wymagają gleby zagrożone erozją wodną.
The influence of soil cultivation on soil water management, which determines yielding of plants under extreme weather phenomena - periodic droughts or intense rainfall, is presented. The deterioration of soil condition and water circulation in soil due to improper cultivation and other field work was discussed. Technical and technological remedies were presented, improving the soil's ability to infiltrate, retain and provide water to plants. In the summary, it was found that measures improving soil water management are possible in any tillage system, and specific conservation measures are required by soils endangered by water erosion.

Opis:: Water erosion remains a major concern on the marly slopes. Where erosive processes continue to increase and continue to pose serious problems and where knowledge is still insufficient on erodibility and its evolution and on solutions to soil erosion problems. The aim of this work is to contribute to the understanding of the functioning of soils on marl substrate in relation to erosion and to evaluate the effectiveness of the anti-erosion measures used in this type of environment. The Isser watershed, where several anti-erosion techniques were used, is the subject of this study. The analysis of the anti-erosion installations shows that most of the developments have been made according to standards and have worked well. But their effectiveness is different from one technique to another. The earthen thresholds seem to be the most suitable and the most effective. The effectiveness of earthen structures is summed up in stability, durability, cost-effectiveness, sediment storage, flood plating and water storage for a significant length of time, and had a positive impact on reducing erosion and the silting rate of the dam. The gabion thresholds also have a better stability and a good seating, but they are very sensitive and can undergo damage that reduces their effectiveness with regard to erosion. Dry stone thresholds are the least desirable and are often inadequate and inefficient in this type of terrain. A purely mechanical and/or biological vision in this type of environment is however insufficient, the mechanical arrangements associated with the biological developments are more effective.
Erozja wodna jest głównym problemem na stokach skał marglowych. Tam właśnie procesy erozyjne nasilają się i stwarzają poważne problemy, a wiedza na temat erozyjności i możliwych rozwiązań w odniesieniu do erozji gleb jest nadal niewystarczająca. Celem tej pracy była próba określenia podatności gleb na podłożu marglowym na erozję i ocena skuteczności działań przeciwerozyjnych stosowanych w takim środowisku. Obiektem badań była zlewnia Isser w Algierii, gdzie zastosowano kilka technik przeciwerozyjnych. Analiza instalacji przeciwerozyjnych wykazała, że większość z nich wykonano zgodnie z normami i działały one poprawnie. Ich efektywność była różna. Najbardziej odpowiednie i skuteczne okazały się stopnie ziemne. Efektywność ziemnych struktur ocenia się na podstawie stabilności, trwałości, kosztów, spłaszczania fali powodziowej i długiego przetrzymywania wody i osadów, co miało pozytywny wpływ na ograniczenie erozji i zamulanie zbiornika. Konstrukcje gabionowe odznaczały się stabilnością i dobrym posadowieniem, ale były bardzo wrażliwe i ulegały uszkodzeniom, co ograniczało ich skuteczność w przeciwdziałaniu erozji. Najmniej pożądane były konstrukcje kamienne, często nieodpowiednie i mało wydajne na takich terenach. Czysto mechaniczne lub biologiczne podejście do problemu jest niewystarczające, dopiero powiązanie mechanicznych rozwiązań z elementami biologicznymi może przynieść pożądany skutek.
