The technology of desalination of fine-textured soils using deep tillage, leaching operations and chemical reclamation agents includes the calculation of doses of ameliorants and leaching requirements, methods and timing of reclamation, soil treatment, selection of crops, and the need for fertilizers on reclamation lands. The stages of preparation of the fields before the application of ameliorants are reviewed. Initially, the fields are divided into lots, the location of loose ameliorants clamps is determined. The options for overall and selective land reclamation are considered. When conducting selective reclamation, it is necessary to locate the solonetzic spots and mark them with range poles. The options for cultivating the soil of irrigated lands characterized by increased density of the subsurface soil horizon of more than 1.4 t/m3 are reviewed. The most pressed are the solonetzic soils with a poor structure or without it. The most preferred methods of cultivating degraded soils (deep loosening or plowing) are identified, which are one of the necessary techniques to provide the greatest depth, degree and speed of soil desalinization. The options for leaching of chloride-sulfate loamy soils, chloride-sulfate salinization and soda salinization are considered.

This paper presents the two approaches used in creating specialized web corpora of Croatian tourism in Japanese for their usage in building a specialized learners’ dictionary. Both approaches use the WebBootCat technology (Baroni et al. 2006, Kilgarriff et al. 2014) to automatically create specialized web corpora. The first approach creates the corpora from the selected seed words most relevant to the topic. The second approach specifies a number of web pages that cover tourism-oriented information on specified regions, cities, and sites in Croatia available in Japanese, which are then used for web corpora creation inside the Sketch Engine platform. Both approaches provide specialized web corpora small in size, but quite useful for lexical profiling in the specific field of tourism. In the process of dictionary creation, the second approach has proven to be especially useful for the selection of lexical items, while both approaches have proven to be highly useful for the exploration and selection of authentic examples from the corpora. The research exposes some shortcomings in Japanese language processing, such as errors in the lemmatization of some culturally specific terms and indicates the need to refine existing language processing tools in Japanese. The Japanese-Croatian bilingual learner’s dictionary (Srdanović 2018) is currently in the pilot phase and is being used and built by learners and teachers through the open-source dictionary platform Lexonomy (Mechura 2017). In addition to the fact that work on the bilingual dictionary is useful as a means for training students in language analysis and description using modern technologies (e.g. corpora, corpus query systems, dictionary editing platform), the dictionary is also important in educating new personnel capable of working in tourism using the Japanese language, which is strongly needed. In future, the same approach could be used for creating specialized corpora and dictionaries for Japanese and other language pairs.

Women make essential contributions to agriculture and rural economic activities in all developing countries. Even though women contribute 60 to 80% of the labour in agriculture and animal husbandry, their involvement in selection of suitable crops and adoption of innovative and good management practices is very low. The study reported that sampled women respondents have shown participation in all the selected agriculture and livestock activities excluding marketing and financial management. The study put forth that very less households witness female participation in agriculture and livestock activities related decision making. Some of the important reasons for their subdued role in decision making in agricultural production could be lack of awareness about new opportunities and modern technologies, inadequate facilities for training and capacity building and poor access to extension workers for consultation whenever needed.

We have studied the possibility of increasing the production of young carp by applying a set of intensification measures and the introduction of innovative production methods, when growing it in artificial reservoirs. Works that has been carried out works provided with technology of cultivation of young fishes as one of the first stages of production of marketable products in aquaculture, secures the selection of qualitative and viable breeding material, providing it with appropriate environmental conditions for normal growth and development, search of optimum and balanced compound feeds which will supplement natural fodder base of ponds, and carrying out of complex measures concerning intensification of fish farming taking into account natural-climatic and geographical-zonal features of a separate economy. The main purpose of the work was to improve the technology of growing young fish in the carp farm of Ltd "Mykolaivska RMS" when using in the feeding of this year's granular feed. Generally accepted hydrochemical, hydrobiological and fish farming methods were used in order to achieve this goal. The technological features of growing carp fish planting material at low planting densities were studied in the ponds of the experimental fishery. The effect of land reclamation, fertilization of ponds to improve the natural feed base, feeding fish with granular feed with a well-balanced content of nutrients and biologically active substances, with constant control of temperature and hydrochemical regimes of ponds on morphometric parameters expediency of carrying out such measures in fisheries. Our research results indicate that the natural fodder basis of ponds of the experimental carp farm Ltd "Mykolaivska RMS" does not fully meet the regulatory conditions for growing young carp and carrying out the above set of intensification measures in combination with feeding young carp granular concentrated organic feed environmentally friendly and economically feasible.

This report presents detailed histograms of data from the Regulated Substances Library (RSL) developed by the Illinois Department of Transportation (IDOT). RSL data are provided for state and IDOT region, IDOT district, and county spatial subsets to examine the spatial variability and its relationship to thresholds defining natural background concentrations. The RSL is comprised of surficial soil chemistry data obtained from rights-of-way (ROW) subsurface soil sampling conducted for routine preliminary site investigations. A selection of 22 inorganic soil analytes are examined in this report: Al, Sb, As, Ba, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Ni, K, Se, Na, Tl, V, and Zn. RSL database summary statistics, mean, median, minimum, maximum, 5th percentile, and 95th percentile, are determined for Illinois counties and for recognized environmental concern, non-recognized environmental concern, and de minimis site contamination classifications.

There are so many things made of concrete, glass and metal in modern cities. All of this displace nature and there is no space for planting. Plants produce oxygen and clean the environment. That is why the landscaping of the roofs of buildings is a kind of compensation in landscaping. The article is about studying methods of creating extensive green roofs from the origin to nowadays. The work includes the study of historical, architectural and regulatory documents and some literary sources. It also includes some facts from the history of green roofs creation, which appeared in the 9th century, on the example of the old house of the Vikings, who lived on the territory of the Faroe Islands. There is a comparative analysis of historical and modern technologies in the article. The design features of extensive roof landscaping are considered. The study revealed modern techniques of extensive landscaping, as well as a list of plants that are resistant to roof landscaping. Recommendations for the usage of waterproof materials like bitumen roll and other are given. The modern approach to the selection of substrates for growing plants on extensive green roofs is also considered. The study revealed modern techniques of extensive landscaping, as well as a list of plants that are resistant to roofing landscaping. It has been revealed that modern materials significantly reduce the specific weight of the construction and ensure the excellent efficiency of the system and the viability of plants during the all working lifespan of the roof. They are discussed the technology of growing planting material for roof landscaping like moss or sedum mats, growing plants in pallets and multiboards, etc.
