Soil hydraulic properties are required in various modelling schemes. We propose a consistent spatial soil hydraulic database at 7 soil depths up to 2\uffc2\uffa0m calculated for Europe based on SoilGrids250m and 1\uffc2\uffa0km datasets and pedotransfer functions trained on the European Hydropedological Data Inventory. Saturated water content, water content at field capacity and wilting point, saturated hydraulic conductivity and Mualem\uffe2\uff80\uff90van Genuchten parameters for the description of the moisture retention, and unsaturated hydraulic conductivity curves have been predicted. The derived 3D soil hydraulic layers (EU\uffe2\uff80\uff90SoilHydroGrids ver1.0) can be used for environmental modelling purposes at catchment or continental scale in Europe. Currently, only EU\uffe2\uff80\uff90SoilHydroGrids provides information on the most frequently required soil hydraulic properties with full European coverage up to 2\uffc2\uffa0m depth at 250\uffc2\uffa0m resolution.150\u00a0\u03bcm in diameter (pores draining freely with gravity) were 0.124, 0.096 and 0.095\u00a0m 3 \u00a0m \u22123 under CT, MT and ZT; and 0.110, 0.104 and 0.101\u00a0m 3 \u00a0m \u22123 under S\u2013W, S\u2013L and S\u2013P, respectively. Saturated hydraulic conductivity values in all the studied soil depths were significantly greater under ZT than those under CT (range from 300 to 344\u00a0mm\u00a0day \u22121 ). The observed k ( h ) values at 0\u201375\u00a0mm soil depth under ZT were significantly higher than those computed under CT at all the suction levels, except at \u221210, \u2212100 and \u2212400\u00a0kPa suction.

Such practice may result in soil structure degradation which can significantly reduce water infiltration causing runoff and erosion processes. An alternative opportunity is given by the use of cover crops which eliminates most of the disadvantages of conventional tillage. An experiment was carried out from 2007 to 2009 in a mature and rainfed olive grove located in Southern Italy with the aim to evaluate the effect of different soil management techniques on soil structure and soil water content and storage along the profile. The experimental site was characterised by a slope gradient ranging from 0 to 16%. Since 2000, the olive grove was subjected to two different management systems: sustainable system, SS (no-tillage, spontaneous vegetation cover, annual recycling of pruning material) and conventional system, CS (tillage, no recycling of pruning material). Modifications of soil structure induced by the two different management systems were quantified by micromorphometric analysis of macroporosity. Soil hydrological behavior was determined by field saturated hydraulic conductivity (Ksat) measurements. Soil water content was measured at 10/15-day intervals by gypsum resistivity blocks placed in flat and steep areas (summit, backslope, and footslope) of both systems at different soil depths (25, 50, 75, 100, 150 and 200\u00a0cm). In the SS soil macroporosity was not very high (about 10%) but homogeneously distributed along the profile which favored the vertical water movement down to deeper horizons. In the CS the occurrence of soil crusting and of compacted layers along the profile hindered infiltration and percolation of rainfall water influencing the soil water content below the 100\u00a0cm layer. The SS was able to better store water from rainfall, received during the autumn\u2013winter period, especially in the deepest soil layer (from 100 to 200\u00a0cm). This was evident especially in the steep area at the summit position, where the water amounts stored by SS were 45 and 17% higher than those retained by the CS in 2007 and 2009, respectively. During summer such reserves were available for the olive root systems which usually, under the driest conditions, explore the deep soil zone in search of water. Under our experimental conditions, no yield reduction was observed due to the prompt mowing of the spontaneous cover crops. Therefore, the suitable use of cover crops should be communicated to the olive farmers and strongly recommended within agricultural policy strategies for its evident agronomical and environmental benefits (increase of soil organic carbon, soil structure improvement, reduction of soil and water losses, carbon sequestration).", "keywords": ["2.

Saturated hydraulic conductivity (K) is a key property for evaluating soil water movement and quality. Most studies on spatial variability of K have been performed soil at a field or smaller scale. Therefore, the aim of this work was to assess (quantify) the spatial distribution of K at the larger regional scale in south-eastern Poland and its relationship with other soil properties, including intrinsic sand, silt, and clay contents, relatively stable organic carbon, cation exchange capacity (CEC) and temporally variable water content (WC), total porosity (FI), and dry bulk density (BD) in the surface layer (0\uffe2\uff80\uff9320\uffc2\uffa0cm). The spatial relationships were assessed using a semivariogram and a cross-semivariogram. The studied region (140\uffc2\uffa0km 2 ) with predominantly permeable sandy soils with low fertility and productivity is located in the south-eastern part of Poland (Podlasie region). The mean sand and organic carbon contents are 74 and 0.86 and their ranges (in %) are 45\uffe2\uff80\uff9395 and 0.002\uffe2\uff80\uff933.75, respectively. The number of individual samples varied from 216 to 228 (for K, WC, BD, FI) to 691 for the other soil properties. The best fitting models were adjusted to the empirical semivariogram (exponential) and the cross-semivariogram (exponential, Gaussian, or linear) used to draw maps with kriging. The results showed that, among the soil properties studied, K was most variable (coefficient of variation 77.3%) and significantly ( p \uffe2\uff80\uff89<\uffe2\uff80\uff890.05) positively correlated with total porosity (r\uffe2\uff80\uff89=\uffe2\uff80\uff890.300) and negatively correlated with soil bulk density (r\uffe2\uff80\uff89=\uffe2\uff80\uff89\uffe2\uff80\uff93\uffe2\uff80\uff890.283). The normal or close to the normal distribution was obtained by natural logarithmic and root square transformations. The mean K was 2.597\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 and ranged from 0.01 up to 11.54\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 . The spatial autocorrelation (range) of K in the single (direct) semivariograms was 0.081\uffc2\uffb0 (8.1\uffc2\uffa0km), while it favourably increased up to 0.149\uffc2\uffb0\uffe2\uff80\uff930.81\uffc2\uffb0 (14.9\uffe2\uff80\uff9381\uffc2\uffa0km) in the cross-semivariograms using the OC contents, textural fractions, and CEC as auxiliary variables. The generated spatial maps allowed outlining two sub-areas with predominantly high K above 3.0\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 in the northern sandier (sand content\uffe2\uff80\uff89>\uffe2\uff80\uff8974%) and less silty (silt content\uffe2\uff80\uff89<\uffe2\uff80\uff8922%) part and, with lower K in the southern part of the study region. Generally, the spatial distribution of the K values in the study region depended on the share of individual intrinsic textural fractions. On the other hand, the ranges of the spatial relationship between K and the intrinsic and relatively stable soil properties were much larger (from\uffe2\uff80\uff89~\uffe2\uff80\uff8915 to 81\uffc2\uffa0km) than between K and the temporally variable soil properties (0.3\uffe2\uff80\uff930.9\uffc2\uffa0km). This knowledge is supportive for making decisions related to land management aimed at alteration of hydraulic conductivity to improve soil water resources and crop productivity and reduce chemical leaching. Plastic pollution in terrestrial environments is a global issue due to its adverse effects on soil health, with negative impacts on ecosystem services and food production. However, the enormous heterogeneity of both plastic and soil characteristics complicate the assessment of the impact and overall trends in plastic-induced changes in soil properties beyond experimental conditions. In this work, we have carried out a systematic and in-depth review of the existing literature on the impact of plastics on soil physical properties. To this end, we have quantified the effects of macro- (MaP, >5000 \uffce\uffbcm) and micro-plastics (MiP, <5000 \uffce\uffbcm) on soil bulk density, soil porosity, water-stable aggregates (WSAs), saturated hydraulic conductivity, and soil moisture at field capacity (FC), based on four characteristics of plastics: polymer types, shapes and sizes of plastic particles, and plastic concentrations in soil. Results showed that MaPs and MiPs significantly modified the values of the analyzed soil physical properties compared to the control without plastic in over 50% of the experimental dataset, albeit with a large variability, from a reduction to an increase in values, depending on the specific experimental conditions and the soil physical property. Depending on the plastic concentration, soil bulk density and porosity decreased moderately (4%\uffe2\uff80\uff936%) with MiP and MaP. MiP reduced WSA by an average of 20%, ranging from a 40% decrease to a 20% increase depending on the shapes and concentration of MiP. Saturated hydraulic conductivity changed depending on the polymer types, shapes, and concentrations of MaP and MiP, varying from a 70% decrease to a 40% increase. Soil water content at FC varied depending on the soil texture, and concentration and sizes distribution of conventional MiP, decreasing from 10% to 65%. However, biodegradable plastic increased soil water content at FC. The few studies available provide evidence that not enough attention is being paid to soil physical properties influenced by plastic input. It is recommended to consider the wide range of characteristics of MaP and MiP and their effects on soil physical properties in future studies, for an advance understanding of the impact of MiP and MaP on soil health in the medium-long term under different environmental conditions.Management systems may lead to a loss of soil physical quality as a result of removal of the plant cover and excessive agricultural mechanization. The hypothesis of this study was that the soil aggregate stability, bulk density, macro- and microporosity, and the S index and saturated hydraulic conductivity may be used as indicators of the soil physical quality. The aim was to study the effects of different periods and managements on the physical attributes of a medium-textured Red Oxisol under soybean and corn for two growing seasons, and determine which layers are most susceptible to variations. A completely randomized experimental design was used with split plots (five treatments and four layers), with four replications. The treatments in 2008/09 consisted of: five years of no-tillage (NTS5), seven years of no-tillage (NTS7), nine years of no-tillage (NTS9), conventional tillage (CTS) and an adjacent area of native forest (NF). The treatments were extended for another year, identified in 2009/10 as: NTS6, NTS8, NTS10, CTS and NF. The soil layers 0-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.30 m were sampled. The highest S index values were observed in the treatment CTS in the 0-0.05 m layer (0.106) and the 0.05-0.10 m layer (0.099) in 2008/09, and in the 0-0.05 m layer (0.066) in 2009/10. This fact may be associated with soil turnover, resulting in high macroporosity in this treatment. In contrast, in the NTS, limiting macroporosity values were observed in some layers (below 0.10 m\uffc2\uffb3 m-3). Highest aggregate stability as well as the highest saturated hydraulic conductivity (K\uffce\uffb8) values were observed in NF in relation to the other treatments. In 2009/10, the K\uffce\uffb8 in NF differed only from NTS10. This study showed that the use of the S index alone cannot be recommended as an absolute indicator of the soil physical quality, even at values greater than 0.035.

Soil organic matter is a key resource base for agriculture. However, its content in cultivated soils is low and often decreases. This study aimed at examining the effects of long-term application of chicken manure (CM) and spent mushroom substrate (SMS) on organic matter accumulation, acidity, and hydraulic properties of soil. Two podzol soils with sandy texture in Podlasie Region (Poland) were enriched with recycled CM (10 Mg ha\u22121) and SMS (20 Mg ha\u22121), respectively, every 1\u20132 years for 20 years. The application of CM and SMS increased soil organic matter content at the depths of 0\u201320, 20\u201340, and 40\u201360 cm, especially at 0\u201320 cm (by 102\u2013201%). The initial soil pH increased in the CM- and SMS-amended soil by 1.7\u20132.0 units and 1.0\u20131.2 units, respectively. Soil bulk density at comparable depths increased and decreased following the addition of CM and SMS, respectively. The addition of CM increased field water capacity (at \u2013100 hPa) in the range from 45.8 to 117.8% depending on the depth within the 0\u201360 cm layer. In the case of the SMS addition, the value of the parameter was in the range of 42.4\u201348.5% at two depths within 0\u201340 cm. Depending on the depth, CM reduced the content of transmission pores (>50 \u00b5m) in the range from 46.3 to 82.3% and increased the level of residual pores (<0.5 \u00b5m) by 91.0\u2013198.6%. SMS increased the content of residual pores at the successive depths by 121.8, 251.0, and 30.3% and decreased or increased the content of transmission and storage pores. Additionally, it significantly reduced the saturated hydraulic conductivity at two depths within 0\u201340 cm. The fitted unsaturated hydraulic conductivity at two depths within the 0\u201340 cm layer increased and decreased in the CM- and SMS-amended soils, respectively. The results provide a novel insight into the application of recycled organic materials to sequester soil organic matter and improve crop productivity by increasing soil water retention capacity and decreasing acidity. This is of particular importance in the case of the studied low-productivity sandy acidic soils that have to be used in agriculture due to limited global land resources and rising food demand.

The objective of this study was to determine the short-term (2006-2009) effects of conventional and conservational tillage practices on selected soil physical properties of a heavy clay soil under two wheat-corn and wheatlegume rotation in a semi-arid Mediterranean Region. Treatments included conventional tillage with residue incorporated in soil (CT1), conventional tillage with burned residue (CT2), reduced tillage with heavy tandem disc-harrow (RT1), reduced tillage with rotary tiller (RT2), reduced tillage with heavy tandem disc harrow fallowed by no-tillage (RNT) and no tillage (NT).

Determining these functions by using direct methods is hampered by excessive time and unaffordable costs required for field activities and laboratory analyses. Pedotransfer functions (PTFs) are widely-used indirect techniques enabling soil hydraulic properties to be predicted by using easily-retrievable soil information. In a parametric evaluation, the predictive capability of PTFs is examined by comparing measured and estimated soil water retention parameters and saturated hydraulic conductivity. Yet information about the performance of PTFs for specific modeling applications is mandatory to evaluate PTF effectiveness in greater depth. This approach is commonly defined as functional evaluation. New hydrological insights for the region: The best performing four PTFs selected in the parametric evaluations are tested under two functional evaluations. The first encompasses a spatial interpolation with a geostatistical technique, whereas the second employs Hydrus-1D to simulate the water balance components along an experimental transect.

Abstract. Peatlands are important natural sources of atmospheric methane (CH4) emissions. The emissions are strongly influenced by the diffusion of oxygen into the soil and of CH4 from the soil to the atmosphere. This diffusion, in turn, is controlled by the structure of macropore networks. The characterization of peat pore structure and connectivity through complex network theory approaches can give insight into how the relationship between the microscale pore space properties and CH4 emissions on a macroscopic scale is shaped. The formation of anaerobic pockets, which are local hotspots of CH4 production in unsaturated peat, can also be conceptualized through a pore network approach. In this study, we extracted interconnecting macropore networks from three-dimensional X-ray micro-computed tomography (\u00b5CT) images of peat samples and evaluated local and global connectivity metrics for the networks. We also simulated the water retention characteristics of the peat samples using a pore network modeling approach and compared the simulation results with measured water retention characteristics. The results showed large differences in peat macropore structure and pore network connectivity between vertical soil layers. The macropore space was more connected and the flow paths through the peat matrix were less tortuous near the soil surface than at deeper depths. In addition, macroporosity, structural anisotropy, and average pore throat diameter decreased with depth. Narrower and more winding air-filled diffusion channels may reduce the rate of CH4 transport as the distance from the peat layer to the soil\u2013air interface increases. Hysteresis was found to affect the evolution of the volume of connected air-filled pore space in unsaturated peat. Thus, the formation of anaerobic pockets may occur in a smaller soil volume and methanogenesis may be slower when the peat is wetting compared to drying conditions. This hysteretic behavior should be taken into account in biogeochemical models to explain the hotspots and episodic spikes of CH4 emissions. The network analysis also suggests that both local and global network connectivity metrics, such as the network average clustering coefficient and closeness centrality, might serve as proxies for assessing the efficiency of CH4 diffusion in air-filled pore networks. However, the applicability of the network metrics was restricted to the high-porosity near-surface layer. The spatial extent and global continuity of the pore network and the spatial distribution of the pores may be reflected in different network metrics in contrasting ways.

However, little attention is given to how this incorporated manure affects soil physical properties. This study assessed the hydraulic properties and aggregate stability of five Nigerian benchmark soils of varied textures under different rates of poultry manure application. The soil types were Iwo, Apomu, Egbeda, Oba, and Itagunmodi series, as well as continuously cropped land with extensively degraded soil. The soils were sampled at 0-15 cm soil depth (plough-layer) and subsequently air-dried and sieved through a 20 mm mesh. For each soil type, 0, 2.5, 5, 7.5, and 10 tons ha-1 of cured poultry manure were applied, and the experiment was replicated three times, resulting in a total of 90 samples (6 soil types x 5 manure levels x 3 replicates). The samples were arranged in completely randomized design and maintained at 75% field capacity for six weeks. At the end of week six, bulk density, aggregate stability, unsaturated soil hydraulic conductivity, sorptivity, pH, organic carbon, and total nitrogen were analyzed. Data were analyzed using analysis of variance and means were separated using Duncan's multiple range test at p\u22640.05. Results revealed that the soils\u2019 texture ranged from sandy loam, loamy sand and clay loam. Soil bulk density decreased with increased incorporation of poultry manure. Generally, unsaturated hydraulic conductivity increased with the incorporation of poultry manure across all the soil series except for Apomu and Oba series. Sorptivity and aggregate stability increased with the incorporation of poultry manure. Soil pH increased with poultry manure incorporation in Apomu, Oba, Iwo, Itagunmodi and the highly cultivated Iwo series, but reduced in Egbeda series. As expected, organic carbon and total nitrogen increased with poultry manure application. Conclusively, poultry manure improved soil hydraulic properties and soil aggregation, which has positive implications on water quality and availability, groundwater recharge, erosion control, fertilizer use efficiency, plant growth, biodiversity and sustainable soil use", "keywords": ["Water stable aggregate", "Soil texture", "Unsaturated hydraulic conductivity", "Sorptivity", "Tropical soil", "Poultry manure"], "contacts": [{"organization": "Akinde, Bamikole, Tijani, Fatai Oladapo, Ibitoye, Rotimi George, Oyedele, Durodoluwa Joseph,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.16316472"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.16316472", "name": "item", "description": "10.5281/zenodo.16316472", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.16316472"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-07-22T00:00:00Z"}}, {"id": "10.5281/zenodo.17187559", "type": "Feature", "geometry": null, "properties": {"license": "unspecified", "updated": "2026-06-25T16:28:50Z", "type": "Dataset", "title": "Gap-filled subset of the Peatland Mid-Infrared Database (1.0.0)", "description": "Introduction This is a gap-filled subset of the Peatland Mid-Infrared Database (1.0.0) (pmird database) stored in the rds format from the R programming language.

Abstract. Peatlands are important natural sources of atmospheric methane (CH4) emissions. The emissions are strongly influenced by the diffusion of oxygen into the soil and of CH4 from the soil to the atmosphere. This diffusion, in turn, is controlled by the structure of macropore networks. The characterization of peat pore structure and connectivity through complex network theory approaches can give insight into how the relationship between the microscale pore space properties and CH4 emissions on a macroscopic scale is shaped. The formation of anaerobic pockets, which are local hotspots of CH4 production in unsaturated peat, can also be conceptualized through a pore network approach. In this study, we extracted interconnecting macropore networks from three-dimensional X-ray micro-computed tomography (\u00b5CT) images of peat samples and evaluated local and global connectivity metrics for the networks. We also simulated the water retention characteristics of the peat samples using a pore network modeling approach and compared the simulation results with measured water retention characteristics. The results showed large differences in peat macropore structure and pore network connectivity between vertical soil layers. The macropore space was more connected and the flow paths through the peat matrix were less tortuous near the soil surface than at deeper depths. In addition, macroporosity, structural anisotropy, and average pore throat diameter decreased with depth. Narrower and more winding air-filled diffusion channels may reduce the rate of CH4 transport as the distance from the peat layer to the soil\u2013air interface increases. Hysteresis was found to affect the evolution of the volume of connected air-filled pore space in unsaturated peat. Thus, the formation of anaerobic pockets may occur in a smaller soil volume and methanogenesis may be slower when the peat is wetting compared to drying conditions. This hysteretic behavior should be taken into account in biogeochemical models to explain the hotspots and episodic spikes of CH4 emissions. The network analysis also suggests that both local and global network connectivity metrics, such as the network average clustering coefficient and closeness centrality, might serve as proxies for assessing the efficiency of CH4 diffusion in air-filled pore networks. However, the applicability of the network metrics was restricted to the high-porosity near-surface layer. The spatial extent and global continuity of the pore network and the spatial distribution of the pores may be reflected in different network metrics in contrasting ways.

Plastic pollution in terrestrial environments is a global issue due to its adverse effects on soil health, with negative impacts on ecosystem services and food production. However, the enormous heterogeneity of both plastic and soil characteristics complicate the assessment of the impact and overall trends in plastic-induced changes in soil properties beyond experimental conditions. In this work, we have carried out a systematic and in-depth review of the existing literature on the impact of plastics on soil physical properties. To this end, we have quantified the effects of macro- (MaP, >5000 \uffce\uffbcm) and micro-plastics (MiP, <5000 \uffce\uffbcm) on soil bulk density, soil porosity, water-stable aggregates (WSAs), saturated hydraulic conductivity, and soil moisture at field capacity (FC), based on four characteristics of plastics: polymer types, shapes and sizes of plastic particles, and plastic concentrations in soil. Results showed that MaPs and MiPs significantly modified the values of the analyzed soil physical properties compared to the control without plastic in over 50% of the experimental dataset, albeit with a large variability, from a reduction to an increase in values, depending on the specific experimental conditions and the soil physical property. Depending on the plastic concentration, soil bulk density and porosity decreased moderately (4%\uffe2\uff80\uff936%) with MiP and MaP. MiP reduced WSA by an average of 20%, ranging from a 40% decrease to a 20% increase depending on the shapes and concentration of MiP. Saturated hydraulic conductivity changed depending on the polymer types, shapes, and concentrations of MaP and MiP, varying from a 70% decrease to a 40% increase. Soil water content at FC varied depending on the soil texture, and concentration and sizes distribution of conventional MiP, decreasing from 10% to 65%. However, biodegradable plastic increased soil water content at FC. The few studies available provide evidence that not enough attention is being paid to soil physical properties influenced by plastic input. It is recommended to consider the wide range of characteristics of MaP and MiP and their effects on soil physical properties in future studies, for an advance understanding of the impact of MiP and MaP on soil health in the medium-long term under different environmental conditions.

Soil water retention (SWR) is an important soil property related to soil structure, texture, and organic matter (SOM), among other properties. Agricultural management practices affect some of these properties in an interdependent way. In this study, the impact of management-induced changes of soil organic carbon (SOC) on SWR is evaluated in five long-term experiments in Europe (running from 8 up to 54 years when samples were taken). Topsoil samples (0\u201315 cm) were collected and analysed to evaluate the effects of three different management categories, i.e., soil tillage, the addition of exogenous organic materials, the incorporation of crop residues affecting SOC and water content under a range of matric potentials. Changes in the total SOC up to 10 g C kg\u22121 soil (1%) observed for the different management practices, do not cause statistically significant differences in the SWR characteristics as expected. The direct impact of the SOC on SWR is consistent but negligible, whereas the indirect impact of SOC in the higher matric potentials, which are mainly affected by soil structure and aggregate composition, prevails. The different water content responses under the various matric potentials to SOC changes for each management group implies that one conservation measure alone has a limited effect on SWR and only a combination of several practices that lead to better soil structure, such as reduced soil disturbances combined with increased SOM inputs can lead to better water holding capacity of the soil.

Abstract. Hydro-pedotransfer functions\u00a0(PTFs) relate easy-to-measure and readily available soil information to soil hydraulic properties\u00a0(SHPs) for applications in a wide range of process-based and empirical models, thereby enabling the assessment of soil hydraulic effects on hydrological, biogeochemical, and ecological processes. At least more than 4 decades of research have been invested to derive such relationships. However, while models, methods, data storage capacity, and computational efficiency have advanced, there are fundamental concerns related to the scope and adequacy of current PTFs, particularly when applied to parameterise models used at the field scale and beyond. Most of the PTF development process has focused on refining and advancing the regression methods, while fundamental aspects have remained largely unconsidered. Most soil systems are not represented in PTFs, which have been built mostly for agricultural soils in temperate climates. Thus, existing PTFs largely ignore how parent material, vegetation, land use, and climate affect processes that shape SHPs. The PTFs used to parameterise the Richards\u2013Richardson equation are mostly limited to predicting parameters of the van\u00a0Genuchten\u2013Mualem soil hydraulic functions, despite sufficient evidence demonstrating their shortcomings. Another fundamental issue relates to the diverging scales of derivation and application, whereby PTFs are derived based on laboratory measurements while often being applied at the field to regional scales. Scaling, modulation, and constraining strategies exist to alleviate some of these shortcomings in the mismatch between scales. These aspects are addressed here in a joint effort by the members of the International Soil Modelling Consortium\u00a0(ISMC) Pedotransfer Functions Working Group with the aim of systematising PTF research and providing a roadmap guiding both PTF development and use. We close with a 10-point catalogue for funders and researchers to guide review processes and research.

Soil hydraulic properties are required in various modelling schemes. We propose a consistent spatial soil hydraulic database at 7 soil depths up to 2\uffc2\uffa0m calculated for Europe based on SoilGrids250m and 1\uffc2\uffa0km datasets and pedotransfer functions trained on the European Hydropedological Data Inventory. Saturated water content, water content at field capacity and wilting point, saturated hydraulic conductivity and Mualem\uffe2\uff80\uff90van Genuchten parameters for the description of the moisture retention, and unsaturated hydraulic conductivity curves have been predicted. The derived 3D soil hydraulic layers (EU\uffe2\uff80\uff90SoilHydroGrids ver1.0) can be used for environmental modelling purposes at catchment or continental scale in Europe. Currently, only EU\uffe2\uff80\uff90SoilHydroGrids provides information on the most frequently required soil hydraulic properties with full European coverage up to 2\uffc2\uffa0m depth at 250\uffc2\uffa0m resolution.Saturated hydraulic conductivity (K) is a key property for evaluating soil water movement and quality. Most studies on spatial variability of K have been performed soil at a field or smaller scale. Therefore, the aim of this work was to assess (quantify) the spatial distribution of K at the larger regional scale in south-eastern Poland and its relationship with other soil properties, including intrinsic sand, silt, and clay contents, relatively stable organic carbon, cation exchange capacity (CEC) and temporally variable water content (WC), total porosity (FI), and dry bulk density (BD) in the surface layer (0\uffe2\uff80\uff9320\uffc2\uffa0cm). The spatial relationships were assessed using a semivariogram and a cross-semivariogram. The studied region (140\uffc2\uffa0km2) with predominantly permeable sandy soils with low fertility and productivity is located in the south-eastern part of Poland (Podlasie region). The mean sand and organic carbon contents are 74 and 0.86 and their ranges (in %) are 45\uffe2\uff80\uff9395 and 0.002\uffe2\uff80\uff933.75, respectively. The number of individual samples varied from 216 to 228 (for K, WC, BD, FI) to 691 for the other soil properties. The best fitting models were adjusted to the empirical semivariogram (exponential) and the cross-semivariogram (exponential, Gaussian, or linear) used to draw maps with kriging. The results showed that, among the soil properties studied, K was most variable (coefficient of variation 77.3%) and significantly (p\uffe2\uff80\uff89<\uffe2\uff80\uff890.05) positively correlated with total porosity (r\uffe2\uff80\uff89=\uffe2\uff80\uff890.300) and negatively correlated with soil bulk density (r\uffe2\uff80\uff89=\uffe2\uff80\uff89\uffe2\uff80\uff93\uffe2\uff80\uff890.283). The normal or close to the normal distribution was obtained by natural logarithmic and root square transformations. The mean K was 2.597\uffc2\uffa0m\uffc2\uffa0day\uffe2\uff88\uff921and ranged from 0.01 up to 11.54\uffc2\uffa0m\uffc2\uffa0day\uffe2\uff88\uff921. The spatial autocorrelation (range) of K in the single (direct) semivariograms was 0.081\uffc2\uffb0 (8.1\uffc2\uffa0km), while it favourably increased up to 0.149\uffc2\uffb0\uffe2\uff80\uff930.81\uffc2\uffb0 (14.9\uffe2\uff80\uff9381\uffc2\uffa0km) in the cross-semivariograms using the OC contents, textural fractions, and CEC as auxiliary variables. The generated spatial maps allowed outlining two sub-areas with predominantly high K above 3.0\uffc2\uffa0m\uffc2\uffa0day\uffe2\uff88\uff921in the northern sandier (sand content\uffe2\uff80\uff89>\uffe2\uff80\uff8974%) and less silty (silt content\uffe2\uff80\uff89<\uffe2\uff80\uff8922%) part and, with lower K in the southern part of the study region. Generally, the spatial distribution of the K values in the study region depended on the share of individual intrinsic textural fractions. On the other hand, the ranges of the spatial relationship between K and the intrinsic and relatively stable soil properties were much larger (from\uffe2\uff80\uff89~\uffe2\uff80\uff8915 to 81\uffc2\uffa0km) than between K and the temporally variable soil properties (0.3\uffe2\uff80\uff930.9\uffc2\uffa0km). This knowledge is supportive for making decisions related to land management aimed at alteration of hydraulic conductivity to improve soil water resources and crop productivity and reduce chemical leaching.

Soil organic matter is a key resource base for agriculture. However, its content in cultivated soils is low and often decreases. This study aimed at examining the effects of long-term application of chicken manure (CM) and spent mushroom substrate (SMS) on organic matter accumulation, acidity, and hydraulic properties of soil. Two podzol soils with sandy texture in Podlasie Region (Poland) were enriched with recycled CM (10 Mg ha\u22121) and SMS (20 Mg ha\u22121), respectively, every 1\u20132 years for 20 years. The application of CM and SMS increased soil organic matter content at the depths of 0\u201320, 20\u201340, and 40\u201360 cm, especially at 0\u201320 cm (by 102\u2013201%). The initial soil pH increased in the CM- and SMS-amended soil by 1.7\u20132.0 units and 1.0\u20131.2 units, respectively. Soil bulk density at comparable depths increased and decreased following the addition of CM and SMS, respectively. The addition of CM increased field water capacity (at \u2013100 hPa) in the range from 45.8 to 117.8% depending on the depth within the 0\u201360 cm layer. In the case of the SMS addition, the value of the parameter was in the range of 42.4\u201348.5% at two depths within 0\u201340 cm. Depending on the depth, CM reduced the content of transmission pores (>50 \u00b5m) in the range from 46.3 to 82.3% and increased the level of residual pores (<0.5 \u00b5m) by 91.0\u2013198.6%. SMS increased the content of residual pores at the successive depths by 121.8, 251.0, and 30.3% and decreased or increased the content of transmission and storage pores. Additionally, it significantly reduced the saturated hydraulic conductivity at two depths within 0\u201340 cm. The fitted unsaturated hydraulic conductivity at two depths within the 0\u201340 cm layer increased and decreased in the CM- and SMS-amended soils, respectively. The results provide a novel insight into the application of recycled organic materials to sequester soil organic matter and improve crop productivity by increasing soil water retention capacity and decreasing acidity. This is of particular importance in the case of the studied low-productivity sandy acidic soils that have to be used in agriculture due to limited global land resources and rising food demand.

Especially under wet soil conditions, when soil is susceptible to compaction, heavy wheel load field traffic can lead to harmful soil compaction. This data set contains soil data from a wheeling experiment with an agricultural vehicle (2-axle combine harvester with bunker; total weight: 17 t). The experiment was conducted in 2016 on an agricultural test field in Adenstedt (Hildesheim district, Lower Saxony, Germany) during the harvest campaign. The soil type is Stagnic Luvisol derived from Loess and was conventionally tilled with a plough up to a depth of 28 cm. The cultivated crop was winter wheat. For the wheeling experiment, a combine harvester with full bunker volume passed defined plots in the field. In the inner field area, the number of wheel passes were 2 and in the headlands the number of wheel passes were 6. The sampling sites were both located in the inner field area and in the headlands. To investigate changes in soil physical parameters, soil structure, and soil functions caused by combine harvester driving, undisturbed soil cores (100 cm\u00b3) were taken before (unwheeled) and after wheeling (wheeled). The unwheeled soil samples were taken in 22, 35, and 50 depth and the wheeled soil samples in 20, 35, and 50 cm depth. In the inner field area, two soil pits were sampled per wheeling variant and in the headlands, one soil pit was sampled per wheeling variant. Additionally, the soil biopores were counted in every one of the three soil depths. A total of 30 undisturbed soil samples were taken per each soil pit, 10 per each soil depth.5 of the 10 undisturbed sampling rings were used to investigate soil water retention and the other 5 for saturated hydraulic conductivity. The determination of pF values was conducted in the soil laboratory using sand and clay boxes as well as pressure pots according to DIN ISO 11274. Saturated hydraulic conductivity was analyzed using a soil water permeameter (open system) according to ISO / FDIS 17312. The soil parameters total pore volume, air capacity, field capacity, usable field capacity, permanent wilting point, dry bulk density, and current water content during soil sampling were derived from the soil laboratory results.\n\nResearch domain: Soil Sciences", "formats": [{"name": "CSV"}], "keywords": ["Soil", "Top soil", "Subsoil", "soil compaction", "Soil pore system", "Soil porosity", "Soil macropores", "Field capacity", "Wilting point", "Hydraulic conductivity", "agriculture", "Vehicles", "Harvesters", "Tillage", "Conservation tillage", "Conventional tillage", "Ploughing", "management", "Management techniques", "On-farm research", "Field experimentation", "Traffic", "Soil sampling", "Bodenfunktion", "Bodenstruktur", "Physikalische Ver\u00e4nderung", "Bodenwasser", "Bodenschutz", "Bodenuntersuchung", "Probenahme", "Boden", "opendata", "Soil physical parameters", "Soil density", "Dry bulk density", "Soil water content", "Soil deformation", "Soil hydraulic properties", "Soil water retention", "Air capaciy", "Plant available water", "Agricultural machineries", "Agricultural management", "Soil management", "Field experiment", "Wheeling experiment", "Field traffic", "Soil conserving traffic"], "contacts": [{"name": "Weise, Maike", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "maike.weise@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Ortmeier, Berthold", "organization": "-", "position": null, "roles": ["other"], "phones": [{"value": null}], "emails": [{"value": "-"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": null}]}, {"name": "Brunotte, Joachim", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "joachim.brunotte@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectManager"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Thomas, Celina", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["dataCurator"], "phones": [{"value": null}], "emails": [{"value": "celina.thomas@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' -

Soil organic matter is a key resource base for agriculture. However, its content in cultivated soils is low and often decreases. This study aimed at examining the effects of long-term application of chicken manure (CM) and spent mushroom substrate (SMS) on organic matter accumulation, acidity, and hydraulic properties of soil. Two podzol soils with sandy texture in Podlasie Region (Poland) were enriched with recycled CM (10 Mg ha\u22121) and SMS (20 Mg ha\u22121), respectively, every 1\u20132 years for 20 years. The application of CM and SMS increased soil organic matter content at the depths of 0\u201320, 20\u201340, and 40\u201360 cm, especially at 0\u201320 cm (by 102\u2013201%). The initial soil pH increased in the CM- and SMS-amended soil by 1.7\u20132.0 units and 1.0\u20131.2 units, respectively. Soil bulk density at comparable depths increased and decreased following the addition of CM and SMS, respectively. The addition of CM increased field water capacity (at \u2013100 hPa) in the range from 45.8 to 117.8% depending on the depth within the 0\u201360 cm layer. In the case of the SMS addition, the value of the parameter was in the range of 42.4\u201348.5% at two depths within 0\u201340 cm. Depending on the depth, CM reduced the content of transmission pores (>50 \u00b5m) in the range from 46.3 to 82.3% and increased the level of residual pores (<0.5 \u00b5m) by 91.0\u2013198.6%. SMS increased the content of residual pores at the successive depths by 121.8, 251.0, and 30.3% and decreased or increased the content of transmission and storage pores. Additionally, it significantly reduced the saturated hydraulic conductivity at two depths within 0\u201340 cm. The fitted unsaturated hydraulic conductivity at two depths within the 0\u201340 cm layer increased and decreased in the CM- and SMS-amended soils, respectively. The results provide a novel insight into the application of recycled organic materials to sequester soil organic matter and improve crop productivity by increasing soil water retention capacity and decreasing acidity. This is of particular importance in the case of the studied low-productivity sandy acidic soils that have to be used in agriculture due to limited global land resources and rising food demand.

Saturated hydraulic conductivity (K) is a key property for evaluating soil water movement and quality. Most studies on spatial variability of K have been performed soil at a field or smaller scale. Therefore, the aim of this work was to assess (quantify) the spatial distribution of K at the larger regional scale in south-eastern Poland and its relationship with other soil properties, including intrinsic sand, silt, and clay contents, relatively stable organic carbon, cation exchange capacity (CEC) and temporally variable water content (WC), total porosity (FI), and dry bulk density (BD) in the surface layer (0\uffe2\uff80\uff9320\uffc2\uffa0cm). The spatial relationships were assessed using a semivariogram and a cross-semivariogram. The studied region (140\uffc2\uffa0km 2 ) with predominantly permeable sandy soils with low fertility and productivity is located in the south-eastern part of Poland (Podlasie region). The mean sand and organic carbon contents are 74 and 0.86 and their ranges (in %) are 45\uffe2\uff80\uff9395 and 0.002\uffe2\uff80\uff933.75, respectively. The number of individual samples varied from 216 to 228 (for K, WC, BD, FI) to 691 for the other soil properties. The best fitting models were adjusted to the empirical semivariogram (exponential) and the cross-semivariogram (exponential, Gaussian, or linear) used to draw maps with kriging. The results showed that, among the soil properties studied, K was most variable (coefficient of variation 77.3%) and significantly ( p \uffe2\uff80\uff89<\uffe2\uff80\uff890.05) positively correlated with total porosity (r\uffe2\uff80\uff89=\uffe2\uff80\uff890.300) and negatively correlated with soil bulk density (r\uffe2\uff80\uff89=\uffe2\uff80\uff89\uffe2\uff80\uff93\uffe2\uff80\uff890.283). The normal or close to the normal distribution was obtained by natural logarithmic and root square transformations. The mean K was 2.597\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 and ranged from 0.01 up to 11.54\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 . The spatial autocorrelation (range) of K in the single (direct) semivariograms was 0.081\uffc2\uffb0 (8.1\uffc2\uffa0km), while it favourably increased up to 0.149\uffc2\uffb0\uffe2\uff80\uff930.81\uffc2\uffb0 (14.9\uffe2\uff80\uff9381\uffc2\uffa0km) in the cross-semivariograms using the OC contents, textural fractions, and CEC as auxiliary variables. The generated spatial maps allowed outlining two sub-areas with predominantly high K above 3.0\uffc2\uffa0m\uffc2\uffa0day \uffe2\uff88\uff921 in the northern sandier (sand content\uffe2\uff80\uff89>\uffe2\uff80\uff8974%) and less silty (silt content\uffe2\uff80\uff89<\uffe2\uff80\uff8922%) part and, with lower K in the southern part of the study region. Generally, the spatial distribution of the K values in the study region depended on the share of individual intrinsic textural fractions. On the other hand, the ranges of the spatial relationship between K and the intrinsic and relatively stable soil properties were much larger (from\uffe2\uff80\uff89~\uffe2\uff80\uff8915 to 81\uffc2\uffa0km) than between K and the temporally variable soil properties (0.3\uffe2\uff80\uff930.9\uffc2\uffa0km). This knowledge is supportive for making decisions related to land management aimed at alteration of hydraulic conductivity to improve soil water resources and crop productivity and reduce chemical leaching. 50 m) in the range from 46.3 to 82.3% and increased the level of residual pores (<0.5 m) by 91.0\u2013198.6%.
