Numerous drivers such as farming practices, erosion, land-use change, and soil biogeochemical background, determine the global spatial distribution of phosphorus (P) in agricultural soils. Here, we revised an approach published earlier (called here GPASOIL-v0), in which several global datasets describing these drivers were combined with a process model for soil P dynamics to reconstruct the past and current distribution of P in cropland and grassland soils. The objective of the present update, called GPASOIL-v1, is to incorporate recent advances in process understanding about soil inorganic P dynamics, in datasets to describe the different drivers, and in regional soil P measurements for benchmarking. We trace the impact of the update on the reconstructed soil P. After the update we estimate a global averaged inorganic labile P of 187 kgP ha\uffe2\uff88\uff921 for cropland and 91 kgP ha\uffe2\uff88\uff921 for grassland in 2018 for the top 0\uffe2\uff80\uff930.3\uffe2\uff80\uff89m soil layer, but these values are sensitive to the mineralization rates chosen for the organic P pools. Uncertainty in the driver estimates lead to coefficients of variation of 0.22 and 0.54 for cropland and grassland, respectively. This work makes the methods for simulating the agricultural soil P maps more transparent and reproducible than previous estimates, and increases the confidence in the new estimates, while the evaluation against regional dataset still suggests rooms for further improvement.A soil-based screening method was used to test tolerance of wheat genotypes to acidity. Plants were grown for 6 days in an acid soil with the pH adjusted to 3.9\uffe2\uff80\uff935.8. The number and length of roots were measured. To validate the method, 12 wheat cultivars of known acidity tolerance and one acid-sensitive barley cultivar were grown on an acid soil in the field with or without amelioration of subsoil acidity. The relative yields of these wheat genotypes on the soil with subsoil acidity ranged from 50 to 89% of yields on soil without subsoil acidity, and were correlated with root growth parameters obtained in the glasshouse. The best correlation was obtained between relative yields in the field (y) and root length per plant (x) at pH 3.9 in the glasshouse (y = \uffe2\uff80\uff9343 + 52*log x, r = 0.95) or root length per plant at pH 3.9 as a percentage of root length at pH 4.8 (y = 1.2 + 46*log x, r = 0.94). Following validation of the glasshouse screening method in the field, 115 wheat genotypes, including cultivars and breeding lines, were screened in the glasshouse. A substantial genotypic variation in acidity tolerance was found, with root length per plant at pH 3.9 ranging from 66 to > 350 mm. Many Western Australian breeding lines displayed better tolerance than existing tolerant wheat cultivars. The screening system can be instrumental in breeding wheat for increased tolerance to acid soils.

Site Characterization, Crop Yields And Soil Chemical Status", "description": "The productivity of Ferrosols used for rainfed agricultural production in the south and central Burnett regions of south-east Queensland was examined in relation to the duration under continuous cultivation. A range of crops grown in on-farm situations during 1986-90 were examined using paired sites to assess the extent of yield decline with time under cropping. The changes in soil chemical characteristics that have occurred during the cropping period were also assessed. All locations showed evidence of a significant reduction in crop growth (50-100%) where continuously cropped sites were compared with sites which had either never been cropped or which had been under grazed grass pasture for >20 years. In the absence of severe late season water deficits, this reduced growth rate was always reflected in lower (21-72%) crop yields at maturity. However, crop dry matter (DM) could interact with crop water use under conditions of late-season water deficit to negate, or even reverse, early growth advantages on previously untilled soil. At least part of the observed yield reduction on continuously cropped soil was due to nutrient deficiencies resulting from depletion of both surface and subsurface reserves during cropping. Long-term cropping has resulted in depletion of soil K and Zn (especially in the subsoil), organic carbon and total N status, and caused significant acidification of both surface and subsoil layers despite the use of lime. The decline in subsoil K status and falling subsoil pH have severe implications for crop performance in dry seasons, when crops rely on subsoil reserves to sustain crop growth. The decline in soil N status has occurred despite a high frequency (>50%) of grain legumes in the crop rotations practised on all farms monitored, and illustrates the small N return from these crops under rainfed conditions. The reduction in soil organic carbon due to cropping was extreme, with continuously cropped areas having organic carbon levels of only 0.9 to 1.5% in the 0-10 cm layer-values which were only 25-40% of levels in untilled soil. Grazed grass leys were only partly successful in restoration of soil organic carbon status.

The effects of annual applications of N and N plus lime were also studied at one site. Both sites received >I700 mm annual rainfall and had strongly acidic, sandy soils. A residual effect of increased pH in the surface soil (0-5 cm depth) was evident after 5 years for lime rates 2200 g/m2. Differences in the nature of the residual effect at each site are discussed in relation to soil acidification, lime dissolution and leaching. High lime rates (>300 g/m2) applied to the soil surface increased pH and reduced extractable A1 in the 10-20 cm depth interval after 12 months. Three years after application, the soil pH at depths of 20-30 and 30-50 cm had been significantly (P < 0.05) increased by surface applications of 600 and 1200 g lime/m2, respectively. The results of this study show that surface application of lime at economic rates (300 to 600 g/m2) can reduce subsoil acidity in coarse-textured soils in high rainfall areas.

However, there has been little corresponding change in the management of nutrients, especially phosphorus (P). This study investigated the effects of tillage and crop rotations on the stratification and transformation of P in soil profiles from 3 tillage/rotation trials encompassing 3 agro-ecological zones of southern Australia. Soil samples were collected from field trials at Longerenong (Vertosol, average rainfall 420\uffe2\uff80\uff89mm), Walpeup (Calcarosol, rainfall 325\uffe2\uff80\uff89mm), and Rutherglen (Chromosol, rainfall 650\uffe2\uff80\uff89mm) in Victoria. Soil samples from various depths were sequentially analysed for organic and inorganic P fractions. Phosphorus accumulated in the surface soil (0\uffe2\uff80\uff930.1\uffe2\uff80\uff89m) across all sites and tillage practices/rotations studied but the proportion of P in different chemical fractions varied markedly among soil types and tillage practice/rotation. In the sandy Calcarosol, a greater proportion of fertiliser P was transformed into labile (resin-P) forms, whereas it tended to accumulate in non-labile pools in the finer textured Vertosol and Chromosol. The effects of tillage and crop rotation were generally confined to the topsoil with P strongly stratified in the topsoil in direct-drill and zero-tillage treatments compared with conventional tillage. The implications for management of P fertilisers in Victorian cropping systems are discussed.

Thus, there is an ongoing need for further research towards sustainable agriculture. Soil is a habitat with great microbial diversity. Many of these microorganisms interact with plants, promoting plant growth, improving nutrient uptake, and making plants less susceptible to pathogens. Therefore, it is important to study microorganisms and their coexistence with plants. The aim of this thesis was to study the root fungal community structure across different fertilisation treatments, crop species and cultivars. Fertilisation treatment had no effect on overall root fungal community composition and richness. However, changes occurred when pathogenic and mutualistic fungi were studied separately. Both manure amendment and alternative organic fertilisation decreased mutualists and increased pathogen richness in comparison to mineral fertilisation. Fertilisation is not the only factor affecting the root mycobiome; the results of this thesis suggest crop species as the most important factor. When the effects of fertilisation treatment and crop species were studied together, the effect of crop species was greater than both fertilisation treatment and the species\u2212treatment interaction. Species richness and diversity were highest in wheat roots and lowest in potato roots. Crops species was the main factor determining differences in root fungal community composition. These results suggest that the root mycobiome is selectively recruited from the soil and related to host-plant physiological or morphological traits. In addition, potato cultivars differed in root fungal community composition and richness, again indicating the importance of host genotype in structuring the root mycobiome. This thesis improves our knowledge of how agricultural practices can shape root fungal community structure. This expertise is important for both scientists and agricultural practitioners. Understanding fungal communities allows us to use them to our advantage, and offers a promising strategy for improving soil quality and crop productivity. Without a fundamental understanding of how fungi respond to different agricultural practices at the field scale, it is not possible to develop these mycobiome-based sustainable farming practices.", "keywords": ["dissertations", "v\u00e4etamine", "soil chemistry", "sordid", "dissertatsioonid", "mullaseened", "p\u00f5llukultuurid", "soil fungi", "sorts", "mullakeemia", "crops", "fertilizing"], "contacts": [{"organization": "Soonvald, Liina", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.15159/emu.91"}, {"rel": "self", "type": "application/geo+json", "title": "10.15159/emu.91", "name": "item", "description": "10.15159/emu.91", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.15159/emu.91"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2022-01-01T00:00:00Z"}}, {"id": "10.1590/s0100-06832007000500025", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-25T16:19:41Z", "type": "Journal Article", "created": "2007-12-19", "title": "Qualidade De Um Solo Sob Diferentes Usos E Sob Cerrado Nativo", "description": "O uso sustent\uffc3\uffa1vel do solo tem-se constitu\uffc3\uffaddo em tema de crescente relev\uffc3\uffa2ncia, em face do aumento das atividades antr\uffc3\uffb3picas.

Soil pH varies by several units among ecosystems. While soil pH is known to be a key driver of plant species composition, we still have a poor understanding of how it affects carbon cycling processes. For instance, soil pH, or its associated chemistry in terms of base cations and organic acids, may affect decomposition rates of dead matter directly, by controlling decomposer composition and activity, and indirectly, by controlling the traits of the plant species and thereby the afterlife effects of those traits on litter decomposition. Leaf and litter pH may play a role in this control. Based on the very limited empirical data available, we hypothesized that variation in species traits including leaf (litter) pH, within and between ecosystems contrasting in soil pH, would have stronger effects on leaf litter decomposition rates than variation in soil chemistry would. 2. We tested this hypothesis by carrying out a \u2018common garden\u2019 litterbed experiment in subtropical SW China, in which leaf litters of the 30 predominant plant species from mid-successional forest on acidic sandstone (soil pH around 4.0) and calcareous soil (pH around 7.5) respectively, were incubated and their decomposition rates measured over two harvests in fourteen months, both in soil plus litter matrix from their \u2018home\u2019 forest and in those from the \u201caway\u201d forest. 3. We found that leaf (litter) trait variation among species and plant functional types, headed by species\u2019 dry matter content but also including tissue pH, was the strongest driver of variation in leaf litter decomposition rates. Surprisingly however, while these effects of interspecific trait variation were very strong among species from the same site, there was no overall difference in litter decomposability between the species from the acidic versus calcareous site. Equally surprising was that this strong difference in pH of soil substrate plus litter matrix from an acidic sandstone site versus a calcareous karst site did not directly affect leaf litter decomposition rates across a given species set. 4. This first attempt to disentangle the multiple potential direct and indirect ways in which soil and leaf (litter) acidity might be related to litter decomposition rates, has important implications for our understanding of soil-plant feedbacks. Based on our forest-based study, we predict that soil-plant feedbacks via acidity are unlikely to be strong in ecosystems with wide-ranging species in terms of their leaf functional traits, including leaf pH.", "keywords": ["litter pH", "Leaf traits", "soil-plant feedbacks", "soil acidity", "Soil chemistry", "calcareous substrate", "15.

By providing an abundance of sites for the sorption and incorporation of major and trace elements, Fe minerals can govern the fate and behaviour of numerous pollutants and nutrients in soils. Furthermore, the reactivity of Fe in redox-dynamic soils produces a web of Fe mineral transformation processes with broad consequences for element cycling. The importance of Fe cycling is no exception in acid sulfate soils, although the high sulfur and low pH conditions produce unique Fe mineral transformation processes and compositions. In acid sulfate soils, jarosite, an Fe-K hydroxysulfate mineral, and ferrihydrite, a common short-range-ordered Fe oxyhydroxide mineral, play a central role in the pedological development of active and post-active acid sulfate soils. Soil pH and the dynamics of metals, such as aluminium, are key to understanding the toxicity of acid sulfate soils and can be directly influenced by jarosite and ferrihydrite transformation processes. Although the transformation of Fe minerals is a key component of biogeochemical processes in redox-active soils, the variables that control the rates and pathways of Fe mineral transformations in soil remain uncertain. The uncertainty arises from the difficulty of tracing molecular processes within a matrix of diverse soil components. Iron minerals are regularly characterised in soils, but the processes that explain the Fe mineral composition of soils cannot be easily resolved. An alternative approach is to perform simplified experiments, such as mixed mineral suspension experiments, under controlled laboratory conditions, to test the effect of individual variables. These systems often use synthetic minerals, although relatively pure jarosite may also be isolated from soils and tested in mixed suspension experiments. While useful to derive mechanistic understanding, the measured outcomes of mixed suspension experiments may not represent the rates and products of transformations that occur in soils. Therefore, the objective of this thesis was to gain new understanding of the stability and transformation of jarosite and ferrihydrite in acid sulfate soils by developing novel experimental techniques to follow the transformation of synthetic jarosite and ferrihydrite directly in soils. The central theme of the thesis is the comparison of jarosite and aluminium-substituted jarosite transformation in experimental media of increasing complexity. The experiments are performed under conditions that are relevant to rice paddy soils because of the importance of rice in global food production, and the unique management of rice paddies whereby regular flooding during the growing season produces distinct redox cycles. In Thailand, large areas of the Chao Phraya River delta are cultivated as rice paddies despite being acid sulfate soils, providing a suitable site to observe the effects of regular redox cycling on the biogeochemistry of Fe minerals in acid sulfate soils. The thesis begins with characterisation of synthetic and natural jarosite mineral composition and reactivity. Spectroscopic techniques (Raman spectroscopy, M\u00f6ssbauer spectroscopy and Energy-dispersive X-ray spectrometry) and X-ray diffraction (XRD) were used to assess the element substitution of mineral samples from two jarosite-alunite synthetic solid solution series. The same characterisation techniques were then applied to a sample of jarosite from an acid sulfate soil in Thailand has a natural Al-for-Fe substitution. The mineral characterisation was followed by a transformation experiment in a mixed-suspension system, similar to experimental designs that have been previously used to study mineral transformation processes. The experiment followed the transformation of the natural jarosite sample from an acid sulfate soil in Thailand and three jarosite samples with variable amounts of Al substitution. The reaction solution mimicked the pH (circumneutral) and Fe(II) content (up to 1:1 ratio of Fe(II) in solution to Fe(III) in solids) of flooded acid sulfate soils. Furthermore, using a 57Fe tracer, the simultaneous transformation processes that explained the distribution of mineral products could be resolved from one another. The transformation experiment revealed the relative reactivity of the minerals in the presence of Fe(II), and created a baseline that could be used to compare traditional mixed-suspension experiments with transformations in complex media such as soil. To advance mineral transformation experiments towards studies in which transformation processes may be followed within a soil matrix, several novel techniques were developed. In a first step, ferrihydrite was incubated for up to twelve weeks in microcosms, each containing 300 g of 5 mM CaCl2 solution and 250 g of one of five paddy soils. The ferrihydrite was buried in the soil within a mesh bag (polyethel terephthalate, 51 \u03bcm pores, 30 mm x 12 mm x 3 mm) that allowed free contact between the synthetic minerals and the pore water, but separated the minerals from direct contact with the soil matrix. The mineral products of the transformation were identified and quantified by Rietveld fitting of XRD patterns. Further, the spatial arrangements of the ferrihydrite and transformation products were measured after two weeks by Raman spectroscopy, which could be used to assess the effects of pore water chemistry and diffusion processes on mineral transformation in the mesh bags. The second step involved measuring jarosite and Al-substituted jarosite transformation in flooded topsoil and subsoils from a rice paddy located on the Bangkok Plain in Central Thailand using an adaptation of the mesh bag method. To test the effect of pore water on the transformation of jarosite in soil, mesh bags were filled with synthetic jarosite and aluminium-jarosite and incubated in topsoils and subsoils, both in laboratory mesocosms and directly in the field. Then, the effect of the soil matrix was tested by completing a parallel experiment using mesh bags containing soil that was pre-enriched with synthetic 57Fe-labelled jarosite and aluminium-substituted jarosite. To facilitate the deployment and collection of small mesh bags in large soil volumes, the mesh bags were inserted into soils using custom-designed 3D-printed sample holders. At three timepoints within twelve weeks, one set of mesh bags were removed from the soil. Transformation products were identified and quantified in the pure jarosite and aluminium-jarosite mesh bags using Rietveld fitting of XRD patterns, while the fate of the 57Fe in enriched soil mesh bags was traced using 57Fe M\u00f6ssbauer spectroscopy. Performing experiments in increasingly complex media provides an insight into the effect of experimental design on the observation of Fe mineral transformations and provides new information regarding the transformation rates and pathways of jarosite and ferrihydrite within full complexity of soil media. Indeed, this thesis demonstrates that the complex chemistry, biological activity, and physical arrangement of components in the soil have strong effects on the rate and products of jarosite and ferrihydrite transformation processes. The transformation of jarosite and Al-substituted jarosite in mixed-suspension experiments presented in this thesis, in agreement with previous mixed-suspension experiments on both jarosite and ferrihydrite, occurred within a matter of hours. By contrast, the rate of ferrihydrite, jarosite and Al-jarosite transformation in soil pore and in direct contact with the soil matrix occurred over the course of several weeks or months. In the ferrihydrite mesh bags, slow ferrihydrite transformation kinetics on the outer rim of the mesh bag, and deep in the core of the mesh bag, indicated that the sorption of chemical components of soil pore water and diffusion limitations of Fe(II) in pore water could be reasons for the slower rates of transformation in soil. In addition, both Al-for-Fe substitution and Fe(II) concentration in solution were important factors that altered the rate of mineral transformation. The different incubation conditions for jarosite and Al-jarosite also altered the products of the transformation. Whereas the hydrolysis of jarosite in the absence of Fe(II) resulted primarily in the formation of ferrihydrite, jarosite transformation in the presence of Fe(II) led to ferrihydrite, goethite and lepidocrocite formation. The Fe oxyhydroxide products were consistent with Fe(II)-catalysed transformation, and Fe(II)-catalysed recrystallisation of jarosite may have occurred concurrently. Aluminium-for-iron substitution hindered the formation of lepidocrocite formation in favour of ferrihydrite and goethite. Similar product phases occurred when jarosite and Al-jarosite were reacted with pore water from acid sulfate soils, indicating that similar transformation pathways may define the mineral products of jarosite transformations when the jarosite occurs as accumulations of pure mineral in soil. However, non- or poorly crystalline phases predominated in the transformation products when jarosite or Al-jarosite were incubated in direct contact with the soil matrix, indicating that the transformation of jarosite under these circumstances was governed by different pathways and processes. The new insights into the transformation of ferrihydrite, jarosite and Al-jarosite in acid sulfate soils demonstrate that phases previously considered meta-stable may participate in the biogeochemistry of soil over period of several months. In the context of rice cultivation, the transformation processes may affect the biogeochemistry of the soils throughout the growing season. The formation of poorly crystalline minerals following the transformation in flooded soils may have positive consequences on the sequestration of other trace and major elements that were associated with the ferrihydrite, jarosite or Al-jarosite prior to the transformation. However, the stabilisation of reduced Fe in the soil matrix may have the opposite effect, promoting the mobility of other ions in solution. The methods used to incubate jarosite and ferrihydrite in soils are easily adaptable to new experimental questions involving the behaviour of Fe-bearing minerals in soil. Therefore, the findings open up a new class of experiments within environmental mineralogy and biogeochemistry, that can help to uncover the processes that occur in the environment and explain the natural variation in the composition of Fe phases in soil.", "keywords": ["jarosite", "iron biogeochemistry", "soil chemistry", "acid sulfate soil", "laboratory study", "ferrihydrite", "soil", "soil incubation", "redox chemistry", "goethite", "iron minerals", "2.

By providing an abundance of sites for the sorption and incorporation of major and trace elements, Fe minerals can govern the fate and behaviour of numerous pollutants and nutrients in soils. Furthermore, the reactivity of Fe in redox-dynamic soils produces a web of Fe mineral transformation processes with broad consequences for element cycling. The importance of Fe cycling is no exception in acid sulfate soils, although the high sulfur and low pH conditions produce unique Fe mineral transformation processes and compositions. In acid sulfate soils, jarosite, an Fe-K hydroxysulfate mineral, and ferrihydrite, a common short-range-ordered Fe oxyhydroxide mineral, play a central role in the pedological development of active and post-active acid sulfate soils. Soil pH and the dynamics of metals, such as aluminium, are key to understanding the toxicity of acid sulfate soils and can be directly influenced by jarosite and ferrihydrite transformation processes. Although the transformation of Fe minerals is a key component of biogeochemical processes in redox-active soils, the variables that control the rates and pathways of Fe mineral transformations in soil remain uncertain. The uncertainty arises from the difficulty of tracing molecular processes within a matrix of diverse soil components. Iron minerals are regularly characterised in soils, but the processes that explain the Fe mineral composition of soils cannot be easily resolved. An alternative approach is to perform simplified experiments, such as mixed mineral suspension experiments, under controlled laboratory conditions, to test the effect of individual variables. These systems often use synthetic minerals, although relatively pure jarosite may also be isolated from soils and tested in mixed suspension experiments. While useful to derive mechanistic understanding, the measured outcomes of mixed suspension experiments may not represent the rates and products of transformations that occur in soils. Therefore, the objective of this thesis was to gain new understanding of the stability and transformation of jarosite and ferrihydrite in acid sulfate soils by developing novel experimental techniques to follow the transformation of synthetic jarosite and ferrihydrite directly in soils. The central theme of the thesis is the comparison of jarosite and aluminium-substituted jarosite transformation in experimental media of increasing complexity. The experiments are performed under conditions that are relevant to rice paddy soils because of the importance of rice in global food production, and the unique management of rice paddies whereby regular flooding during the growing season produces distinct redox cycles. In Thailand, large areas of the Chao Phraya River delta are cultivated as rice paddies despite being acid sulfate soils, providing a suitable site to observe the effects of regular redox cycling on the biogeochemistry of Fe minerals in acid sulfate soils. The thesis begins with characterisation of synthetic and natural jarosite mineral composition and reactivity. Spectroscopic techniques (Raman spectroscopy, M\u00f6ssbauer spectroscopy and Energy-dispersive X-ray spectrometry) and X-ray diffraction (XRD) were used to assess the element substitution of mineral samples from two jarosite-alunite synthetic solid solution series. The same characterisation techniques were then applied to a sample of jarosite from an acid sulfate soil in Thailand has a natural Al-for-Fe substitution. The mineral characterisation was followed by a transformation experiment in a mixed-suspension system, similar to experimental designs that have been previously used to study mineral transformation processes. The experiment followed the transformation of the natural jarosite sample from an acid sulfate soil in Thailand and three jarosite samples with variable amounts of Al substitution. The reaction solution mimicked the pH (circumneutral) and Fe(II) content (up to 1:1 ratio of Fe(II) in solution to Fe(III) in solids) of flooded acid sulfate soils. Furthermore, using a 57Fe tracer, the simultaneous transformation processes that explained the distribution of mineral products could be resolved from one another. The transformation experiment revealed the relative reactivity of the minerals in the presence of Fe(II), and created a baseline that could be used to compare traditional mixed-suspension experiments with transformations in complex media such as soil. To advance mineral transformation experiments towards studies in which transformation processes may be followed within a soil matrix, several novel techniques were developed. In a first step, ferrihydrite was incubated for up to twelve weeks in microcosms, each containing 300 g of 5 mM CaCl2 solution and 250 g of one of five paddy soils. The ferrihydrite was buried in the soil within a mesh bag (polyethel terephthalate, 51 \u03bcm pores, 30 mm x 12 mm x 3 mm) that allowed free contact between the synthetic minerals and the pore water, but separated the minerals from direct contact with the soil matrix. The mineral products of the transformation were identified and quantified by Rietveld fitting of XRD patterns. Further, the spatial arrangements of the ferrihydrite and transformation products were measured after two weeks by Raman spectroscopy, which could be used to assess the effects of pore water chemistry and diffusion processes on mineral transformation in the mesh bags. The second step involved measuring jarosite and Al-substituted jarosite transformation in flooded topsoil and subsoils from a rice paddy located on the Bangkok Plain in Central Thailand using an adaptation of the mesh bag method. To test the effect of pore water on the transformation of jarosite in soil, mesh bags were filled with synthetic jarosite and aluminium-jarosite and incubated in topsoils and subsoils, both in laboratory mesocosms and directly in the field. Then, the effect of the soil matrix was tested by completing a parallel experiment using mesh bags containing soil that was pre-enriched with synthetic 57Fe-labelled jarosite and aluminium-substituted jarosite. To facilitate the deployment and collection of small mesh bags in large soil volumes, the mesh bags were inserted into soils using custom-designed 3D-printed sample holders. At three timepoints within twelve weeks, one set of mesh bags were removed from the soil. Transformation products were identified and quantified in the pure jarosite and aluminium-jarosite mesh bags using Rietveld fitting of XRD patterns, while the fate of the 57Fe in enriched soil mesh bags was traced using 57Fe M\u00f6ssbauer spectroscopy. Performing experiments in increasingly complex media provides an insight into the effect of experimental design on the observation of Fe mineral transformations and provides new information regarding the transformation rates and pathways of jarosite and ferrihydrite within full complexity of soil media. Indeed, this thesis demonstrates that the complex chemistry, biological activity, and physical arrangement of components in the soil have strong effects on the rate and products of jarosite and ferrihydrite transformation processes. The transformation of jarosite and Al-substituted jarosite in mixed-suspension experiments presented in this thesis, in agreement with previous mixed-suspension experiments on both jarosite and ferrihydrite, occurred within a matter of hours. By contrast, the rate of ferrihydrite, jarosite and Al-jarosite transformation in soil pore and in direct contact with the soil matrix occurred over the course of several weeks or months. In the ferrihydrite mesh bags, slow ferrihydrite transformation kinetics on the outer rim of the mesh bag, and deep in the core of the mesh bag, indicated that the sorption of chemical components of soil pore water and diffusion limitations of Fe(II) in pore water could be reasons for the slower rates of transformation in soil. In addition, both Al-for-Fe substitution and Fe(II) concentration in solution were important factors that altered the rate of mineral transformation. The different incubation conditions for jarosite and Al-jarosite also altered the products of the transformation. Whereas the hydrolysis of jarosite in the absence of Fe(II) resulted primarily in the formation of ferrihydrite, jarosite transformation in the presence of Fe(II) led to ferrihydrite, goethite and lepidocrocite formation. The Fe oxyhydroxide products were consistent with Fe(II)-catalysed transformation, and Fe(II)-catalysed recrystallisation of jarosite may have occurred concurrently. Aluminium-for-iron substitution hindered the formation of lepidocrocite formation in favour of ferrihydrite and goethite. Similar product phases occurred when jarosite and Al-jarosite were reacted with pore water from acid sulfate soils, indicating that similar transformation pathways may define the mineral products of jarosite transformations when the jarosite occurs as accumulations of pure mineral in soil. However, non- or poorly crystalline phases predominated in the transformation products when jarosite or Al-jarosite were incubated in direct contact with the soil matrix, indicating that the transformation of jarosite under these circumstances was governed by different pathways and processes. The new insights into the transformation of ferrihydrite, jarosite and Al-jarosite in acid sulfate soils demonstrate that phases previously considered meta-stable may participate in the biogeochemistry of soil over period of several months. In the context of rice cultivation, the transformation processes may affect the biogeochemistry of the soils throughout the growing season. The formation of poorly crystalline minerals following the transformation in flooded soils may have positive consequences on the sequestration of other trace and major elements that were associated with the ferrihydrite, jarosite or Al-jarosite prior to the transformation. However, the stabilisation of reduced Fe in the soil matrix may have the opposite effect, promoting the mobility of other ions in solution. The methods used to incubate jarosite and ferrihydrite in soils are easily adaptable to new experimental questions involving the behaviour of Fe-bearing minerals in soil. Therefore, the findings open up a new class of experiments within environmental mineralogy and biogeochemistry, that can help to uncover the processes that occur in the environment and explain the natural variation in the composition of Fe phases in soil.", "keywords": ["jarosite", "iron biogeochemistry", "soil chemistry", "acid sulfate soil", "laboratory study", "ferrihydrite", "soil", "soil incubation", "redox chemistry", "goethite", "iron minerals", "2.

However, the sorption capacity of biochar for these elements can vary widely depending on biochar nature and metal properties. Currently, there is no clear methodology to pre-screen biochars for their suitability as adsorbents for these elements. Therefore, to facilitate biochar selection for application in soil restoration, this study explored the relationships between the physico-chemical properties of five plant-based biochars and their capacity to immobilize Cd(II), Pb(II) and Zn(II). Batch experiments using synthetic soil pore water were used to assess the sorption of these elements. The sorption isotherms described by the Hill model indicated that PTE sorption capacity followed the order Pb(II) > Cd(II) >Zn(II) regardless of biochar type in mono-element systems. Preferential sorption of Pb(II) limited the immobilization of Cd(II) and Zn(II) in multi-element systems. ATR-FTIR and SEM-EDX spectroscopy studies indicated that Cd(II) and Pb(II) sorption was mediated by complexation with carboxylic groups, cation-\u03c0 interactions and precipitation with phosphates and silicates, while Zn(II) sorption occurred mainly by complexation with phenolic groups and precipitation with phosphates. A high correlation (>0.8) between Electrical Conductivity, Cation Exchange Capacity, pH and sorption capacity was identified for all metals tested, highlighting the electrostatic nature of the sorption mechanisms involved. Biochars derived from herbaceous feedstock were better candidates for remediation of soil polluted with Cd(II), Pb(II) and Zn(II), rather than wood-derived biochar.

However, the sorption capacity of biochar for these elements can vary widely depending on biochar nature and metal properties. Currently, there is no clear methodology to pre-screen biochars for their suitability as adsorbents for these elements. Therefore, to facilitate biochar selection for application in soil restoration, this study explored the relationships between the physico-chemical properties of five plant-based biochars and their capacity to immobilize Cd(II), Pb(II) and Zn(II). Batch experiments using synthetic soil pore water were used to assess the sorption of these elements. The sorption isotherms described by the Hill model indicated that PTE sorption capacity followed the order Pb(II) > Cd(II) >Zn(II) regardless of biochar type in mono-element systems. Preferential sorption of Pb(II) limited the immobilization of Cd(II) and Zn(II) in multi-element systems. ATR-FTIR and SEM-EDX spectroscopy studies indicated that Cd(II) and Pb(II) sorption was mediated by complexation with carboxylic groups, cation-\u03c0 interactions and precipitation with phosphates and silicates, while Zn(II) sorption occurred mainly by complexation with phenolic groups and precipitation with phosphates. A high correlation (>0.8) between Electrical Conductivity, Cation Exchange Capacity, pH and sorption capacity was identified for all metals tested, highlighting the electrostatic nature of the sorption mechanisms involved. Biochars derived from herbaceous feedstock were better candidates for remediation of soil polluted with Cd(II), Pb(II) and Zn(II), rather than wood-derived biochar. Overall, this study provides evidence of the direct relationship between specific properties of plant-based biochars (pH and EC) and their suitability as adsorbents for some PTEs in soil systems.", "keywords": ["H1-99", "Trace elements", "Environmental management", "Science (General)", "Soil pore water", "Soil pollution", "0211 other engineering and technologies", "Correlation analysis", "Cooperative sorption", "02 engineering and technology", "15.

The aim of the research is to observe changes in a wide range of soil characteristics, especially chemical properties, occurring at specific time intervals under the influence of agricultural and non-agricultural human activities. The research is carried out in 5-year cycles, starting from 1995, as part of the national network, which consists of 216 measuring and control points, located on soils used for agriculture throughout the country. At the designated sampling points, soil profiles are sampled and the following indicators are determined: granulometric composition (8 fractions), % humus, % CaCO3, pH, hydrolytic acidity, exchange acidity, content of plant-available forms of phosphorus (P2O5), potassium (K2O), magnesium (Mg) and sulphur (S-SO4), content of: total nitrogen, organic carbon, polycyclic aromatic hydrocarbons, interchangeable calcium, potassium, magnesium and sodium, electrical conductivity and radioactivity. The following are also calculated: ratio C : N, soil salinity, cationic sorption capacity, sum of exchangeable bases and degree of saturation with alkaline cations. In soil samples, the content of total forms shall also be determined: calcium, magnesium, potassium, sodium, aluminium, iron, phosphorus, manganese, cadmium, copper, chromium, nickel, lead, zinc, cobalt, vanadium, lithium, beryllium, boron, strontium and lanthanum.", "formats": [{"name": "Environmental monitoring facilities GML Application Schema"}, {"name": "OGC:WFS"}], "keywords": ["Urz\u0105dzenia do monitorowania \u015brodowiska", "Gleba", "Pa\u0144stwowy Monitoring \u015arodowiska", "The State Environmental Monitoring", "monitoring", "urz\u0105dzenie do monitorowania \u015brodowiska", "environmental monitoring facility", "obszar bada\u0144 gleby", "soil research area", "monitoring chemizmu gleb ornych", "monitoring of chemistry of arable soils", "gleba", "soil", "obserwacja", "observation", "chemizm gleb", "soil chemistry", "ocena jako\u015bci gleb", "soil quality assessment", "program", "programme", "National"], "contacts": [{"name": null, "organization": "G\u0142\u00f3wny Inspektorat Ochrony \u015arodowiska", "position": null, "roles": ["custodian"], "phones": [{"value": "+48515236721"}], "emails": [{"value": "inspire@gios.gov.pl"}], "addresses": [{"deliveryPoint": ["ul.
