A multitiered approach for grassland ecosystem services mapping and assessment: The Viva Grass tool
Throughout the second half of the 20th Century, the area of semi-natural grasslands in the Baltic States decreased substantially, due to agricultural abandonment in some areas and intensification in more productive soil types. In order to halt the loss of biodiversity and ecosystem services provided by grasslands, the LIFE+ programme funded project, LIFE Viva Grass, aims at developing an integrated planning tool that will support ecosystem-based planning and sustainable grassland management. LIFE Viva Grass integrated planning tool is spatially explicit and allows the user to assess the provision and trade-offs of grassland ecosystem services within eight project case study areas in Estonia, Latvia and Lithuania.
In order to ensure methodological adaptability, the structure of the LIFE Viva Grass integrated planning tool follows the framework of the tiered approach. In a multi-tier system, each consecutive tier entails an increase in data requirements, methodological complexity or both. The present paper outlines the adaptation of the tiered approach for mapping and assessing ecosystem services provided by grasslands in the Baltic States. The first tier corresponds to a deliberative decision process: The matrix approach is used to assess the potential supply of grassland ecosystem services based on expert estimations. Expert values are subsequently transferred to grassland units and therefore made spatially explicit. The data collected in the first tier was further enhanced through a Principal Components Analysis (PCA) in order to explore ES bundles in tier 2. In the third tier, Multi-Criteria Decision Analysis is used to target specific policy questions
The contribution of the European Society for Soil Conservation (ESSC) to scientific knowledge, education and sustainability
Soil is an integral component of the global environmental system which supports the quality and diversity of terrestrial life on Earth. Therefore, it is vital to consider the processes and impacts of soil degradation on society, especially on the provision of environmental goods and services, including food security and climate change mitigation and adaptation. Scientific societies devoted to soil science play significant roles in reducing soil degradation and promoting soil conservation by advancing scientific knowledge, education and environmental sustainability.
The ESSC was founded on 4 November 1988, with the aims to:
1.
Support research on soil degradation, soil protection and soil and water conservation.
2.
Provide a network for the exchange of knowledge about soil degradation processes and soil conservation research and practises.
3.
Produce publications on major issues relating to soil degradation and soil and water conservation.
4.
Advise regulators and policy-makers on soil issues, especially soil degradation, protection and conservation.
The societal challenges that can be addressed through better soil protection, advancing knowledge and scientific approaches to soil protection and sustainable management, mean the ESSC embraces the on-going development, application, review and constructive criticism of highly innovative scientific soil conservation methods. In this context, the ESSC analyses and publicizes the roles and functions of soil in natural and human-modified systems and the functional optimization of soils to ensure sustainable environmental protection.

Barriers and opportunities of soil knowledge to address soil challenges: Stakeholders? perspectives across Europe
Climate-smart sustainable management of agricultural soil is critical to improve soil health, enhance food and water security, contribute to climate change mitigation and adaptation, biodiversity preservation, and improve human health and wellbeing. The European Joint Programme for Soil (EJP SOIL) started in 2020 with the aim to significantly improve soil management knowledge and create a sustainable and integrated European soil research system. EJP SOIL involves more than 350 scientists across 24 Countries and has been addressing multiple aspects associated with soil management across different European agroecosystems. This study summarizes the key findings of stakeholder consultations conducted at the national level across 20 countries with the aim to identify important barriers and challenges currently affecting soil knowledge but also assess opportunities to overcome these obstacles. Our findings demonstrate that there is significant room for improvement in terms of knowledge production, dissemination and adoption. Among the most important barriers identified by consulted stakeholders are technical, political, social and economic obstacles, which strongly limit the development and full exploitation of the outcomes of soil research. The main soil challenge across consulted member states remains to improve soil organic matter and peat soil conservation while soil water storage capacity is a key challenge in Southern Europe. Findings from this study clearly suggest that going forward climate-smart sustainable soil management will benefit from (1) increases in research funding, (2) the maintenance and valorisation of long-term (field) ex-periments, (3) the creation of knowledge sharing networks and interlinked national and European in-frastructures, and (4) the development of regionally-tailored soil management strategies. All the above -mentioned interventions can contribute to the creation of healthy, resilient and sustainable soil ecosystems across Europe
Soil sequences atlas. 2
TäistekstThis is the second book in the series of Soil Sequence Atlases. The first volume was published in 2014. Main pedogeographic features are presented in the form of sequences to give a comprehensive picture of soils - their genesis and correlations with the environment in typical landscapes of Central Europe from Estonia furthest north, through Latvia, Lithuania, Poland, Germany, Czechia, Slovakia and Hungary to the southernmost Slovenia. Soils of natural landscapes - loess and sand (continental dunes) - are presented, as well as those of plains of various origin, karst lands, low mountains, and anthropically modified soils. Each chapter presents soil profiles supplemented by landscape information and basic analytical data. Then, genetic interpretations of soil properties related to soil forming agents are given as schematic catenas. When one factor changes while the others are more or less stable, the soil sequence can be recognised. Depending on the dominant soil-forming factor affecting repeated soil patterns, different types can be distinguished. Chapters are arranged roughly in accordance with the main soil-forming process in sequences, and referring to the WRB key (peat formation, vertic and gleyic process, podzolisation, humus accumulation, clay illuviation), with one small exception - the Technosols have been placed at the end of book. The main objective of this book is to present the diversity of relations between soil and landscape, climate, hydrology and human relations, and to present interpretations reflecting the World Reference Base for Soil Resources (2015) classification with comments on the choice of qualifiers. Sixteen Reference Soil Groups are featured, and represented by 67 soil profiles. The secondary objective is pedological education. One of the aims of soil science education is to explain to students the relations between landscape and soil cover. The patterns of soil units within landscapes are to some extent predictable. The collected data is intended as a useful educational tool in teaching soil science, supporting understanding of the reasons for the variability of soil cover, and also as a WRB classification guideline. The Atlas was developed as part of the EU Erasmus+ FACES project (Freely Accessible Central European Soil). Marcin Šwitoniak, Przemyslaw Charzynsk
A global perspective on soil science education at third educational level; knowledge, practice, skills and challenges
The pivotal role of soil as a resource is not fully appreciated by the general public. Improving education in soil science represents a challenge in a world where soil resources are under serious threat. Today’s high school students, the world’s future landowners, agriculturalists, and decision makers, have the potential to change society’s apathy towards soils issues. This research aimed to compare the level of soil education in high and/or secondary schools in forty-three countries worldwide, together comprising 62% of the world's population. Comparisons were made between soil science content discussed in educationally appropriate textbooks via a newly proposed soil information coefficient (SIC). Interviews with teachers were undertaken to better understand how soil science education is implemented in the classroom. Statistical analyses were investigated using clustering. Results showed that gaps in soil science education were most commonly observed in countries where soil science is a non-compulsory or optional subject. Soil science concepts are predominantly a part of geography or environmental science curricula. Consequently, considerable variability in soil science education systems among investigated countries exists. Soil information coefficient‘s outcomes demonstrated that a methodological approach combining textbooks and the use of modern digitally based strategies in the educational process significantly improved soil education performances. Overall, soil science education is under-represented in schools worldwide. Dynamic new approaches are needed to improve pivotal issues such as: i) promoting collaborations and agreements between high school and universities; ii) encouraging workshops and practical exercises such as field activities; and, iii) implementing technology tools. This, in turn, will prepare the next generation to contribute meaningfully towards solving present and future soil problems

A very high diversity of soil groups within relatively similar Quaternary deposits was determined according to international FAO WRB soil classification. Spatial distribution relationships between soil groups, their prefix qualifiers and environmental factors (Quaternary deposits, soil texture, forest types) were ascertained of drained and undrained soils that are characteristic with nutrient poor environmental conditions and nutrient very rich geological deposits, however significant relationships with CORINE Land Cover 2005 classes and topographical situation were not clarified.
The development of predominant soil forming processes (lessivage, decarbonisation, podzolization) are relatively delayed during the initial time period after abandonment of agricultural lands in comparison to forest lands developed on former agricultural lands within boreal-nemoral areas. That is determined by soil texture, lithological and chemical composition in parent material
The obtained results would facilitate the future mapping of the boreo-nemorial region soils on a regional scale of 1:50,000.

Leaching of Contamination from Stabilization/Solidification Remediated Soils of Different Texture
Development of soil and groundwater remediation technologies is a matter of great importance to eliminate historically and currently contaminated sites. Stabilization/solidification (S/S) refers to binding of waste contaminants to a more chemically stable form and thus diminishing leaching of contamination. It can be performed using cement with or without additives in order to stabilize and solidify soil with the contamination in matrix. A series of experiments were done to determine leaching properties of spiked soils of different texture bound with cement. Results of experiments showed, that soil texture (content of sand, silt and clay particles) affects the leaching of heavy metals from stabilized soils
Tree Species Establishment in Urban Forest in Relation to Vegetation Composition, Tree Canopy Gap Area and Soil Factors
The study of density and growth of pine, birch and oak seedlings and saplings in canopy gaps in the urban boreal forest in Riga, Latvia, indicates that natural regeneration can increase diversity in small gaps caused by tree mortality, and can ensure conversion from even-aged pine forest. Abundant regeneration in small gaps showed that light (gap area) was only one of the factors affecting tree regeneration in the gaps. The depth of the O layer and pH were suggested to be important factors for the establishment and growth of pine and birch. For oak, the main factors for establishment and growth were favorable moisture, higher pH and N concentration. Knowledge of ecological factors affecting the establishment of seedlings and growth of saplings of the most common trees species in the urban boreal forest is needed to predict successional trajectories and to aid management
Effects of afforestation of agricultural land with grey alder (Alnus incana (L.) Moench) on soil chemical properties, comparing two contrasting soil groups
Abstract Background Natural afforestation of former agricultural lands with alder species is common in Europe. Symbiotic nitrogen fixation by actinomycetes associated with alder species has been widely used for improvement of soil properties of abandoned agricultural lands, but relatively little is known of the interactions of these processes with soil type and chemical composition. We conducted a space-for time study with soil sampling under and outside grey alder tree canopies on two different soil groups to explore effects of colonisation of former agricultural lands by alder on soil properties. Results The results were analysed using analysis of variance. During the first 25 years after afforestation of former agricultural lands there was a significant increase in content of Ctot, Ntot, K+, Fe3+, Mn2+ and available P in the topsoil (0–10 cm and 11–20 cm) of Dystric Arenosols soils, which are deficient in organic matter. Such trends were not evident in organic matter rich Endostagnic Umbrisols soils, in which exchangeable K+ concentration decreased and exchangeable Fe3+ and Al3+ concentration increased. Conclusions The results show that the effects of grey alder on soil chemical properties depend on initial soil properties. The invasion of agricultural land by grey alder leads to spatial variability of soil chemical properties creating a mosaic pattern
Vegetation changes in boreo-nemoral forest stands depending on soil factors and past land-use during an 80-year period of no human impact
Information on the long-term changes in plant communities that occur without human interference is limited, due to insufficient studies where vegetation can be resurveyed. In 1912, a strict nature protection reserve, with non-intervention management, was established on Moricsala Island in Latvia, located in the boreo-nemoral forest zone. Prior to establishment of the nature reserve, part of the island area was used for agriculture. The island is now covered almost entirely by forest dominated by Quercus robur and Tilia cordata on sandy soils. Resurvey was conducted in 2011 in seventeen plots in which tree layers and the understory vegetation had been described in 1930. The plots were classified into two groups based on tree species composition in 1930, to determine changes in species composition. Differences in understory and tree canopy composition between these groups persisted over the period between the studies, in relation to soil factors and past stand history. Considerable turnover of species occurred, with decrease of species typical of open habitats and replacement by species typical of nemoral (temperate deciduous) forest plant communities. In the past, Quercus robur had likely established in open habitats created by agricultural land-use or past fire, but is presently not regenerating in the understorey.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
