Over a period of more than 140 years, the humus content in the arable layer of the chernozems, as a result of their use in agriculture, decreased by 2.47% or 43.2% from the content of the virgin (natural) chernozem, the rate of humus reduction of was 0.019% annually. Maintaining the annual reduction rate of humus content presents a significant ecological and economic danger for Republic of Moldova. The state quality of the investigated chernozems regarding the content of organic matter is satisfactory. The factors limiting the productivity of chernozems (and other soils) are: low humus and nutrient content, strong compaction and destruction of the arable and post-arable layer. The quality of the chernozem (and the soil resources in general) must be maintained by administering the organic-mineral fertilizers at optimum doses, incorporating plant residues and secondary production in soils, respecting crop rotation with the introduction of alfalfa into the soil, increasing the proportion of leguminous crops up to 20-25%. Key words: agriculture, chernozem, degradation, fertilizer, humus.

  • Fresh Rivers and Salt Springs: Modern Management and Ethno- Management of Water Resources in Eastern Romania

    Fresh Rivers and Salt Springs: Modern Management and Ethno- Management of Water Resources in Eastern Romania

Carol I 11, 700506, Iaşi, Romania; 3 CNRS, Université Paris 1 Panthéon-Sorbonne, UMR Trajectoires, 21 allée de l’Université, 92023, Nanterre cedex - France Abstract. The present study aims to evaluate the competition between the modern management and the ethno-management of the water resources from Eastern Romania. The employment of specific hydrological, ethno-archaeological and spatial analysis methods yielded well delimited specific areas, corresponding to the levels of NaCl present in rivers and springs. The waters from the mountainous and piedmont areas of the Carpathians are directly influenced by the presence of salt deposits. The reduced salinity of the larger water arteries is due to the important liquid discharges that dilute the salts. The recent ethno-archaeological investigations that focused on the approximately 200 salt springs which were identified in the sub-Carpathian areas of Moldavia, have highlighted a well-structured ethno-management system. The modern management of the fresh water resources, developed under governmental and local communal financial support, must be continued with increased intensity. Conversely, an involvement into the ethno-management of the salt-water springs must be generally prohibited; only seldomly, in cases of uttermost necessity, can it interfere with the 8.000-years-old ethno-management of these salt-water springs.

    Moldavia and Maramureş – Micro-Destinations for Relaunching the Romanian Tourism*

    Theoretical and Applied Economics Volume XVIII (2011), No. 10(563), pp. 45-56 Moldavia and Maramureş – Micro-destinations * for Relaunching the Romanian Tourism Aurelia-Felicia STĂNCIOIU Bucharest Academy of Economic Studies [email protected] Ion PÂRGARU “Polytechnica” University of Bucharest [email protected] Nicolae TEODORESCU Bucharest Academy of Economic Studies [email protected] Anca-Daniela VLĂDOI Bucharest Academy of Economic Studies [email protected] Monica Paula RAŢIU Romanian American University of Bucharest [email protected] Abstract. Since Romania holds a rich tourism heritage and a great tourism potential, the tourism division into zones was drawn up as “a possibility toward a superior and complex development of the tourism resources, in a unified vision…” (Erdeli, Gheorghilaş, 2006, p. 264), this representing a permanent concern of the specialists from all fields that are related to the tourism management. Although the criteria for selection and ranking of the tourist attractions have been the subject of some controversies, regarding the types of tourism that can be practiced in these areas, there were arrived almost unanimous conclusions. In order to ensure the representativeness and considering that all historical regions of the contemporary Romania are to the same extent micro- destinations with a substantial “tourism heritage”, the regions of Moldavia (including Bukovina) and Maramureş were merged into one for the elaboration of the research that presents, in essence, the main types of tourism and a part of the treasury of Romanian age-old heritage. Keywords: tourism destination; tourism micro-destination; destination image; regional tourism brand; type of tourism; destination marketing. JEL Code: M31.

    Section Hydrology and Water Resources THE DISTRIBUTION OF SALT MASSIFS AND THE EXPLOITATION OF ANCIENT AND CURRENT RESERVES OF MINERALIZED WATERS WITHIN THE SIRET HYDROGRAPHICAL BASIN (ROMANIA) – CASE STUDY FOR THE EASTERN AREA OF THE EASTERN CARPATHIANS Professor Dr Gheorghe Romanescu1 Associate Professor Dr Marius Alexianu2 Research Assistant Dr Andrei Asăndulesei3 1 “Alexandru Ioan Cuza” University of Iași, Faculty of Geography and Geology, Department of Geography, Romania. 2 “Alexandru Ioan Cuza” University of Iași, Faculty of Letters, Romania. 3 “Alexandru Ioan Cuza” University of Iași, Interdisciplinary Research Department – Field Science, Romania. ABSTRACT The present study proposed to underline the importance of salt-water reserves in the life of the local communities and to quantify the value of certain basic elements that can affect their chemical properties. The salinity does not produce pollution, but only a restriction of water use in certain domains. There is a close connection between the genesis of salt reserves and the emergence of springs, the type of rock, the regional and local climatic regime, the type of hydrographical network supply, and the liquid discharge. The waters within the Carpathian mountainous and sub-mountainous area can be influenced directly by the emergence of salt deposits on the surface. The poorest springs are situated in the area of the Moldavian Subcarpathians, where there are diapiric outcrops. The Neolithic settlements in the east of the Eastern Carpathians attest the oldest use of salt springs in the world. Some springs may be underlined by the humans through animals, mostly the sheep, which looked for salinized fields for their optimal water intake.

Spermatodes- mata occur in all examined taxa within the sawfly grade (Xyelidae-Orussidae inclusive), but are not found in the Apocrita. Using DAPI staining, the numbers of individual sperm per sperma- todesm were calculated and the values obtained are mapped on to the current phylogenetic hy- pothesis. The plesiomorphic spermatodesm in the Hymenoptera, based on that observed in the putatively basal family Xyelidae, contains relatively few sperm, approximately 16. However, in the Tenthredinoidea and in the Siricidae, far larger numbers are found, reaching up to 256 in the Cimbicidae.

Surveys on C. quadrimaculata in various ecologies have been conducted in the provinces (Adyaman, Diyarbakr, Elazğ, Mardin) of Southeastern and Eastern Anatolia regions of Turkey between the years 2010-2014. C. quadrimaculata larvae collected from Amygdalus communis L. (Rosacae) in Adyaman, Diyarbakr, Elazğ, Mardin. There were similarities in the larvae population changes in Adyaman-Diyarbakr and Elazğ-Mardin. The highest density of the larvae was recorded of Besni location in Adyaman province. Population density of the larvae was low in Mardin. Occurrence of the larvae generally observed between April and July in the all of province. C. quadrimaculata overwinter as a pre-pupa in a cocoon in the ground or other protected place, pupating in the spring. In early summer, adults lay eggs in or on plant tissue and the larvae feed on the leaves. Key words: Cimbex quadrimaculata, Almond pest, Hymenoptera, Cimbicidae.
