The issue of the urban soil survey, mapping and classifications (including urban soil diagnostics) seems to be not unified and standardized in the last time research. To contribute to the knowledge profound, we present procedure of the urban soil mapping which was based on the concept of pedo-urban complexes enabling to map urban soils in large or middle-sized scale. The mapping process includes the use of multiple background materials such as land cover/land use map, digital terrain model, satellite images, and soil survey results in the field. The example of this mapping method was demonstrated on Bratislava City in Slovak republic. The Slovak Morphogenetic Soil Classification system (MKSP 2014) and World Reference Base for Soil Resources (WRB 2015) was used for soil map unit’s classification. Concept of the pedo-urban complex (PUC) includes several mapping attributes: urban land use, mapping of soil sealing, mapping of soil units (prevailingly soil association) as well as technogenic substrates. This basis was completed by soil texture, and level of environmental risk. PUC can create some spatial pattern depending on urban land use. Other soil areas are delineated as natural soil types variously influenced by geomorphology or pedology setting. The result of this process is creation of the soil map of Bratislava City which consists of 1,478 areas with soil units. Soil map could be applied in urban planning processes, as very detailed information provided within the map. Also it can be showed some gaps in mapping which should be the topic of further discussions and studies.

"The possibilities of using black walnut (Juglans nigra L.) from a production-ecological point of view in agroforestry systems in Slovakia were tested on the pilot research-demonstration plot of Kosihy nad Ipľom. This tree is a woody plant that is growing to a lesser extent in forest stands but it can be found also in ornamental gardens and parks. However, its potential for agroforestry systems use in the framework of sustainable management of agricultural land has not yet been re-evaluated. It can generate very interesting and promising commodities for farmers, both in terms of fruit production and high-quality wood that is well monetized on the market. The methodology is based on the identification of agro-ecological conditions of black walnut (Juglans nigra L.) growing and proposal of areas suitable for these trees planting (ranked as very suitable, suitable, and unsuitable). The land evaluation units – BPEJs (© VÚPOP Bratislava) were separately evaluated based on several major land properties like climate

The paper evaluates black soils (especially Chernozems) in the Danubian Lowland in terms of their occurrence, mineralogical composition, basic soil properties, soil genesis and classification. The evaluation of black soil is based on the results of the General Survey of Agricultural Soils from the 1960s, the results of which (maps and databases) were processed by the latest digital information and communication technologies. The paper analyses and supplements the more detailed characteristics of the Žitný ostrov area soils, especially Chernozems, but also touches on other related soil types. A detailed field survey of Chernozems, including specific analytical measurements, allowed us to deepen the knowledge and identify differences or similarities of soil types (physical-chemical and micromorphological differences). Attention is mainly paid to the separation of the facies of mycelial carbonate Chernozems of the Danubian Lowland, which are unique in current soil and climatic conditions. A distinctive feature of all mycelial carbonate Chernozems is the presence of a zone of needle calcite (lublinite). In addition to illite, these soils are characterized by a high chlorite content. It has been found that the carbonates of the alluvial deposits of Žitný ostrov, as well as the lower Váh valley, as well as the loess of the Trnava Uplands consist not only of calcite (CaCO3), but also of dolomite (CaMg(CO3)2). Both minerals dominate the clay fraction of all, but especially in Chernozemic soils. The genesis of the soils is supported by micromorphological characteristics, pointing primarily to the paleo-hydromorphic character of the Žitný ostrov soils. Hydromorphic and saline soils, which are part of the Danube Lowland, are also marginally mentioned. Soil classification is based on the morphogenetic principle applied in the Morphogenetic Soil Classification System of Slovakia and compared with the current development of the classification of black soils in the world (FAO International Black Soil Network, World Reference Base for Soil Resources).

"The paper provides an overview of the of anthropogenic substrates issue, which is an essential part of the classification and mapping of anthropogenic soils. These are related to anthropogenic processes, the variability of which is quite large. It reflects number of classification systems of anthropogenic soils, which tend to be quite different in various countries. There is a discussion of the terminology of “anthropedosphere” as an exceptional sphere of anthropogenic soils and substrates investigation, and differentiation of anthropogenic and urban soil terminology is mentioned. The soil-forming substrate is a significant part of the soil mass especially for technogenic soils. Correlation relationships between the individual systems was not yet resolved. Ten soil classification systems over the world were overviewed in relation to applied principles and criteria of anthropogenic substrates. Recognition confirms a lack of anthropogenic substrates system in most soil classification systems and their remarkable diverse used principles. The connecting element is the reference classification of WRB soils with related anthropogenic materials: artefacts, technic hard material and anthropic qualifiers. Comparing systems; several attributes were similar like presence of artifacts or human transported and altered material or human-induced properties like qualifiers Ekranic, Urbic, Spolic or Garbic. As the most elaborate systems can be considered the German Soil Classification, USDA Soil Taxonomy, and Morphogenetic Soil Classification system (MSCS). The main aim of the paper is to evaluate the system of anthropogenic substrates in the MSCS (2014) in the light of latest information in the world and to provide a new proposal for the solution of anthropogenic (also by human transported) substrates (materials) for its revised version.
