Under consideration is the classification of soils and soil-like formations in special landscapes and the football ground in particular. The latter is usually represented by soils subjected to human impacts of varying intensity: from weakly transformed by technogenic processes to artificial soils or technogenic superficial formations. The objects of research are more than 40 football grounds in Russia and the Republic of Byelarus. They differ in the age (exploitation time), regular and intensive technogenic loads, natural conditions and soil properties. The football grounds under study were divided into 3 groups: sports-ground at the age of its exploitation (less than 5 years), sports-mass grounds (30-50 years) and professional football grounds (50-75 years). Every group of football grounds is characteristic of soils and technogenic superficial formations represented by (1) technogenic-natural soils, (2) technogenically transformed soils and (3) technogenic superficial formations. The first two groups include the surface-transformed and disturbed soils, the natural profile of which is weakly changed. The technogenic superficial formations artificially constructed on the buried horizons of natural soils are highly subjected to technogenesis. In dependence on natural and technogenic conditions, age or exploitation time, peculiar features of soil stratum on football grounds it is possible to recognize a postlithogenic type of soddy-podzolic soils as well as 3 synlithogenic types represented by techno-soddy podzolic soil and 2 types of technogenic superficial formations including primitive and soddy quasizems. The evolution trends are striving to develop three subtypes of soddy quasizems under all the bioclimatic conditions including lessive, gleyic and solonetzic ones, whereas under humid conditions of the Moscow region there exist 5 subtypes of techno-soddy podzolic soils represented by lessive, gleyic, technogenically overcompacted, residual-carbonate and chemically polluted ones.

Under consideration are typical profiles of podzolic loamy soils described in many publications on the soils of  Komi Republic with respect to their diagnostics in national and international classifica-tion systems. It is argued  that the podzolic soils should be preferably recognized at the type level with numerous subtypes to reflect the  variations in the profile drainage conditions. In terms of the international soil classifications (FAO/WRB) the  podzolic soils may be correlated with the former Podzoluvisols and recent Retisols better than with the  Albeluvisols of the intermediate versions.

According to various data, the area of grey forest soils in the world is 94–120.2 million ha, in Ukraine – 4.7–5.5 million ha (about 9 % of the country’s territory). The diversity of conditions for the formation of these soils, discussions about their genesis are the causes of different approaches to the classification of grey forest soils. The history of the classification of grey forest soils is analysed; the most common variants of their classification in Ukraine are presented. Seeking to find approximate equivalents, an attempt to find grey forest soils in the classification systems of different countries (Russia, Moldova, Bulgaria, Romania, Czech Republic, Poland, USA, Canada), as well as in the legend of the FAO-UNESCO map and the WRB has been made. To establish exact analogues of soils practically it is impossible due to different principles of classification’s construction. Modern soil classifications of different countries are as close as possible to WRB and “Soil Taxonomy”. The following names of grey forest soils are identified as the most grounded: light grey forest, grey forest and dark grey podzolic. The following equivalents of the WRB nomenclature (2014) for sub-types of grey forest soils are offered: light grey forest – Albic Luvisols, grey forest – Haplic Luvisols, dark grey podzolic – Luvic Greyzemic Phaeozems. To the names of analogues of these soils with gleyic properties, the qualifier “Gleyic” should be added before the name of the reference soil group. The urgent task for soil scientists of Ukraine is to create a new soil classification that would preserve the acquisitions of genetic soil science but took into account the world trends: the allocation of diagnostic horizons and features that have clearly defined quantitative boundaries. In the new classification, it is proposed to combine the light grey and grey forest soils by a separate group, dark grey podzolic soils to be grouped together in a group with podzolic chernozems. The need for such selection is confirmed by the study of the dark grey soils position in different classification systems of the world, most of which these soils are in the chernozemic type group (Mollisols, Phaeozems and Chernozems). Key words: classification, grey forest soils, Greyzems, Luvisols, Mollisols, Phaeozems.

Abstract The article contains a brief history of the development of the soil classification scheme of the Republic of Belarus. It comprises the description of the most widely-used (acknowledged) genetic classification of soils, characteristics of basic taxonomic units (type, subtype, sort, kind, and variation), and characteristics of the 13 main types of Belarusian soils. The map of the soil cover of Belarus and the morphological and genetic characteristics of typical and unique soil varieties are presented. The main problems of the national soil classification and its correlation with the international WRB system are shown.

Current geopolitical and economic conditions for the functioning of railway transport in most post-Soviet states are such that it is extremely difficult to provide required quality of transport services and break-even operations at high expenses for maintaining the railway infrastructure and rolling stock. Dynamics of transportation of the Tajik Railway (TSR) is shown, which displays that most of its sections are classified as low-intensity ones. The paper proposes methodical principles, setting and qualitative analysis of the task of rationalization of operational work and organization of car flows for international transportation, taking into account the specifics of the Tajik Railway. There is a problem of complex maintenance of the efficiency of operational work in modern conditions based on the synthesis of the tasks of self-management (rational internal operational technology of the Tajik Railway) and coordination tasks (technological interaction with railway administrations of other states). Author substantiated the necessity of solving this problem. Proposed classification of technological restrictions and controlled variables in the performance of transport takes into account methods for changing external conditions for the functioning of the railway landfill and methods for increasing internal efficiency of its operation. The search for the solution of the problem involves direct search of variants along its ordered set with clipping of groups of variants that do not correspond to constraints, with the subsequent finding of compromise control over a set of effective alternatives.

The paper contains the results of classification of rivers and streams of the Republic of Moldova according to classic Strahler method. Mentioned method was applied to estimate the hierarchical rank of the stream segments situated in 50 pilot basins using modern GIS techniques and drainage network of the GIS for Water Resources of Moldova. It was estimated that the maximal order of segments is 7 specific for the Raut and Ialpug rivers. Overall, length of 1st order streams forms 50%, while that of 7th order streams - < 1%. Additionally, stream number and frequency as well as drainage density were calculated for pilot river basins.

<p class="Default">In this paper, the current problems associated with the classification of brown earths, are presented. According to the Polish Soil Classification (PSC) (1989, 2011), base saturation is the main parameter for identifying eutrophic and dystrophic brown soils. In practice, however, it is not possible to determine the base saturation value in the field. Therefore, the aim of this study was to estimate the base saturation using a regression equation and create a field guide for brown earths, based on the pH value, measured using a Hellige indicator, and the calcium carbonate content. Determination of the pH ranges enabled the classification of brown earth types in the field. These results suggest that pH can be used as a proxy for base saturation especially in the field. A change in the hierarchy of soil (sub)types is proposed for the new Polish Soil Classification.</p>

The article compares conditions and procedures for the adoption of Constitution and amendments to thecurrent constitution between the Republic of Bulgaria and the Republic of Kazakhstan. The criteria used inthe legal theory for the classification of the constitutions according to the way of their change are used. Bothconstitutions refer to the category of the hard. Bulgaria has a solid core of the constitution, which can onlybe changed by a specially elected institution — a Great (Grand) National Assembly. In Kazakhstan there areeven texts that are not subject to change. The experience of several changes to the two basic laws has beenconsidered. Whit them some of the questions have been answered by juridical theory and practice, whileothers remain open. At the end, conclusions are drawn from the parallel between the changes to the bothconstitutions, some of which are of universal significance.
