Two of the main parameters, which defined the cleaning capacity of cultivated plants and productivity of aquaponic systems, are the type of hydroponic compartment and plant’s growing media. The aim of current research was to compare the cleaning capacity and plant’s productivity of media bed and raft hydroponic sections as a part of a model aquaponic recirculation system. The impact of different plant growing mediums (cotton wool and rockwool) on lettuce yields was also retraced. For the purpose of this research two types of hydroponic sections (media bed and deep water sections) were constructed and integrated into an existing recirculation aquaculture system. For the trial 36 lettuce seedlings were used. Half of the plants were transferred to cotton wool and the other half of the lettuce plants were transferred to rockwool (Grodan®) substrates and afterwards all plants were placed in hydroponic pots. Eighteen lettuce seedlings (half planted on cotton wool and the other half on rockwool (Grodan®) substrate) were planted on the hydroponic section filled with lightweight expanded clay aggregate (LECA) and the other eighteen plants (half planted on cotton wool and the other half on rockwool (Grodan®) substrate) were planted on the floating raft hydroponic section.The hydrochemical parameters were measured during the trial. At the end and middle of the trial the fresh weight of lettuce plants was measured.A better removal capacity in ammonium, nitrate and ortho-phospahte were observed in the LECA section compared with the cleaning capacity in the raft section as a part of experimental aquaponic system. The raft technology showed better plant productivity compared with the one found for the LECA bed technology. The productivity of lettuce plants is highly dependent on the type of plant growing medium, when they are cultivated in the floating raft technology.

The rapid growth of the world population also increases the amount of food needed for the human being`s life. Therefore, applications that increase productivity and through which production can be made throughout the year in plant production come to the forefront in the world. In this context, one of the most important activities is greenhouse cultivation through which production can be made throughout the year by keeping climate conditions under control. Greenhouses are climate-controlled plant production structures in which indoor environment conditions can be controlled and can be kept in accordance with growing conditions. Heating must be performed during the winter period in greenhouses if it is desired to make production throughout the year. In Turkey, almost all of greenhouse production is performed in the Mediterranean region, and the production areas are situated in a relatively limited area in the Southeastern Anatolia Region. In this study, 10-year climate data (Maximum, Minimum and Average Temperature, Humidity, Sunshine Duration and Amounts) of 5 provinces (Diyarbakir, Mardin, Siirt, Batman and Sirnak) in the Tigris basin were achieved by considering the climatic conditions and production capacity of Antalya province, which has the most production areas in Turkey. According to the results obtained, the average minimum temperature for each month showed a statistically significant difference according to the provinces (p<0.01). Consequently, while the highest heating load was 1852.836 W/m2 for a greenhouse of 576 m2 for Antalya province in January during which heating requirement is the maximum, 3887.13 W/m2 and 5615 W/m2 heating load differences were obtained from Mardin and Diyarbakir provinces, respectively.

Written by Barbaros S. KUMBUL, Kamil EKINCI, Ismail TOSUN

In this study, composting of opium poppy processing solid waste with poultry manure and rough sawdust with C/N ratio of 25 (65% opium poppy processing solid waste, 14% poultry manure, and 21% sawdust, dry basis) was conducted using fifteen-identical cylindrical stainless steel reactors, each of which has an effective volume of 100 L. The moisture content of initial mixture was 66%. Five aeration rates (aeration rates executed under set point temperature, Qmin,= 0.5, 1.0, 1.5, 2.0, and 2.5 m3/h) were applied with fan on/off time (min) of 5/25, 7.5/25, and 10/25. The experiment lasted for 7.79 days. In the experiment, the temperature, electrical conductivity (EC), pH, moisture, organic matter, oxygen (O2) and carbon dioxide (CO2) concentrations, total carbon and nitrogen contents were monitored. Dry matter loss, organic matter loss, carbon loss, and nitrogen loss were expressed as functions of Qmin and on/off times. Results showed that the highest losses occurred at the aeration rate of Qmin=1.5 m3/h. Losses as functions of aeration rate with on/off time showed that the highest losses existed at the aeration rate of Qmin=1.5 m3/h with on/off time (min) of 7.5/25-10.0/25.

CONSIDERATIONS ON THE WAYS OF DETERMINING THE MOVEMENT OF THE EARTH'S SURFACE DUE TO THE PHENOMENON OF SUBSIDENCE

Published in Scientific Papers. Series E. Land Reclamation, Earth Observation & Surveying, Environmental Engineering, Vol. V
Written by Ioan VOINA, Maricel PALAMARIU, Iohan NEUNER

The paper aims to present some theoretical and practical aspects related to the movement over time of the land surfaces affected by the groundwater exploitation of multi-layered deposits in the area. The methods and techniques described are intended to facilitate a rigorous observation of the evolution of risk and hazard phenomena, presenting a complex summary of the way of obtaining specialized information, as efficiently and precisely as required by the Romanian legislation regulations. Given that the phenomenon of subsidence keeps on being of a broad interest through its implications on urban planning, environmental protection and on the surface buildings, the issues described in this paper lead to short, medium and long-term forecasts regarding the subsidence due to the exploitation of multi-layered deposits. These forecasts are very important in the sustainable development of the areas affected by underground mining.

Land reclamation engineering technologies habe been succesfully applied to improve crop quality and compensate the natural inconspicuous and counterproductive factors for a long and radical evolution of the agricultural production. Still, an incorrect use of these technologies, inadequate agricultural exploitation and alcaline to salty soils, led to profound ecosystem degradation, up to desertification. It is the case of some specific areas in Braila county, Romania, which degraded from agricultural to desertified land. The paper aims to track the transformation of these areas over a 35 years period and to conclude whether stakeholders should follow the natural path and find a way to work along with the raw environment. The analisys passes in review the transformations of Braila plain from 1974 to 2010, based on graphic analysis of arridity index, Lang pluviometric index and Gaussen obrothermic diagram, corroborated with pedologic conditions, soil quality and climate factors variation, leading to the desertification of more than 2000 hectars, classified nowdays with the IV-th and V-th fertility grade. Administrative measures have been proposed by the local authorities but not applied on the site, due to high costs of implementation and the question to be answer is whether an eco management and economic solutions would better generate profitable use of these desertified soils.

The stands’ regeneration through afforestation does not represent the main modality for insuring the stands’ regeneration, but it is used where the natural regeneration cannot be assured, and when the forests are extend or reintroduced. It may be appreciated that nowadays, the stand’s status is mainly influenced by the climatic, pedo­hydrological and anthropical factors .In this context, we may witness the process of devitalization and trees’ abnormal drying, especially in the arid areas of the country, respectively in the steppe and forest steppe regions, also in Danube meadow regions, in plane and other hilly territories, mainly during dry and extremely dry years. Statistics regarding the beating-up works and rehabilitation of affected plantations within the plantations realized between 2001-2010 by RNP-Romsilva reveal that there were established on a total surface ranged between 5621 and 9239 ha, and 18-25% were damaged and had to be remade. Concerning the supplying of forest reproductive materials, it may be mentioned that during 2001-2011 the seed stand and the seed orchard surfaces decreased, but the seed stands surface for the main scattered and other noble hard wood species increased. The ecological rehabilitation of the degraded forest is necessary and should be realized by promoting species more resistant to more and more dryer site conditions from forest steppe the plane forest and by extension of surfaces covered by Norway spruce in sub alpine region, Stone pine and Mountain pine in the alpine region. Related to the afforestation realized within the state owned forests, it may be noted that they were made in accordance with technical guidelines using the best genetically improved forest reproductive materials, with adapted provenances/ species in different site conditions. We consider that it is mandatory to update the technical guidelines in order to include a more intensive afforestation and forest management processes, conditions that are necessary for obtaining more stable and higher quality stands.

There is no news that the use of GIS technique in the engineering field takes place at high level, and has a very well defined place in environment engineering. This paper shows a sequence of a GIS application in the field of quantification of soil loss as a result of water erosion The GIS application is exemplified in a water catchment of approximately 4000 ha in Berheci Superior of Bacau County, with intensive water erosion processes, both at the surface and in gullies. After the development of databases (graphic and alphanumerical), the determination of connections (keys) between them is very important, in order to enable interrogation. Interrogation ensures the value of GIS application, and in this application we can notice 2 interrogation methods. The development method of the interrogations, as well as the response manner in the own designed concept, with a relational alphanumerical database are shown. This paper shows the importance of correlated databases in the context of statistical analyses for large areas. Following these analyses and by means of the GIS, the most intelligent ecologic and anti-erosional management solutions can be taken in torrential hydrographic water catchments.
