In the last years, zeolites have been researched for a variety of agricultural and environmental applications because possess unique properties: cation-exchange, adsorption, and molecular sieving. Zeolite can be used as soil conditioners, amendments, remediation agents in contaminated soils with heavy metals et all. Because commercially zeolites are expensive the researches have as objectives synthesis of new materials from different materials. These materials are raw or wastes, for example power plant ash, and can to be used effectively in soil applications if understand effects of these in soils or soil-like systems.The aim of this study is synthesis and characterization of zeolitic materials synthesized from power plant ash. Two different zeolite materials, rich in zeolite phases, K–cabazite were obtained from power plant ash, using 3 M KOH solutions at atmospheric pressure, temperature below 90°C and contact time of 4 and 8 hours.New materials were analyzed for their composition and properties. The synthesized products provide a significant increase of CEC (cation exchange capacity) and the high ability to adsorb heavy metal ions (over 39 mg gí1). Because synthesized materials have high cation -exchange capacities that can be used as cation-exchange in a soil. The high cation-exchange capacities determined several researches for using of materials for lead and copper removal from soil.

The experiment was conducted over three years: 2009, 2010 and 2011, in five locations: Fundulea, Calaraúi county; Valu lui Traian, Constanta county; Sarichioi, Tulcea county; Cazasu, Braila county and Caracal, Olt county. These locations were selected as being representative for corn cropping area from South Romania. Eight corn hybrids (F475M, Olt, Paltin, F376 from Fundulea Institute and PR35F38, PR37Y12 , PR36V74, PR37F73 from Pioneer) were tested using two levels of water regime: irrigated with 800 3/ha and non-irrigated. The study showed that the 2009 was less favorable for corn crop in all testing areas, comparing with 2010 and 2011 which were favorable for corn crop. In the case of non-irrigated corn trials the yield was influenced by the climatic conditions of the year, while in the case of irrigated corn trials, the yield was much higher and stable. The hybrid PR36V74 had the highest yield in all irrigated and non irrigated testing locations. Average yield of the hybrids over three years varied between 93.8 q/ha (F475M) and 130,3 q/ha (PR36V74) in non-irrigated conditions, while in irrigated conditions average yield increased significantly by applying of 800 m3/ha varying between 101.2 q/ha (F475M) and 155,9 q/ha (PR36V74).

Drought refers to a temporary decrease in water availability, for example, when it doesn’t rain over a long period of time. On the other hand, water scarcity occurs when the demand for water exceeds the available sustainable resources. Most European countries are affected by the consequences of water scarcity, droughts and land degradation caused by water resources over-exploitation and exacerbated by climate change. The satellite systems present a wide range of new capabilities that can be used to assess and monitor the actual conditions of agro­ecosystems since information can be obtained on remote, wide area, non-destructive and/or real-time bases. Remote sensing data with low spatial resolution and high temporal resolution provide a useful tool for the monitoring of the vegetation activity from global to regional and local scale. The agricultural vegetation condition monitoring is currently possible, ranging from medium spatial resolution satellite derived - products, with daily revisit (NOAA­AVHRR, SPOT-VEGETATION, etc.) to high and very-high spatial resolution, offered by environmental satellites (LANDSAT, SPOT, FORMOSAT, IKONOS, QuickScat etc.) with longer revisit period. The most important parameters are: vegetation indices, maximum greenness during the growing season, total greenness during the growing season, fraction of photosynthetically active radiation and leaf area index.The study is focused on vegetation state assessment based on satellite derived products for drought monitoring (drought duration and intensity). This paper is based on the analysis of several vegetation indexes (NDVI, NDWI, etc) and biophysical parameters (LAI, fAPAR, land surface temperature, etc).The study area is focused on agricultural region situated in the western part of Romania, in the Romanian downstream of Mures River.

The paper aimed to determine the rate of change in swelling behaviour and liquid limit of clayey soils when exposed to natural seawater with respect to distilled water. The four clayey soil samples were gathered with different mineralogy and plasticity characteristics and tested to determine liquid limit and swelling characteristics in the presence of distilled water, tap water and seawater. The seawater effect is most noticed on the swelling behavior for montmorillonitic soils which have high plasticity.

Increased vulnerability of human society to natural hazards is not so much due to a change in the way phenomena manifest, but also to anthropogenic causes, which require more than ever, a pertinent analysis of risk factors and constant involvement of specialists in all fields activity in reducing the negative effects they may cause to people, to the infrastructure or to environmental factors. Safety of structures is one of the main performance requirements for buildings. Expressed in a quality-like manner, this requirement must be completed with quantitative factors.

Aim of the study: The response of some sunflower hybrids in low water-supply conditions. The central part of Dobrogea is chiefly characterized by a warm and droughty climate, with the medium annual temperature of 11ºC and medium annual rainfall of 432,2 mm, which are irregularly distributed during the whole year and therefore for the sunflower crop there isn’t ensured a comfortable humidity regime for a normal development of plants. A decreased sunflower yield is drastic if there is an intervining of the hidric shortage. Taking into consideration the importance of the usage of some drought and torridity resistant genotypes, the work aims to find the most adequate germoplasm for obtaining some profitable crops in low water- supply conditions in the central Dobrogea Plateau. The methods used: The sunflower trial was located at S.C.D.A Valu lui Traian, Constanta County in 2011; bifactorial type it was used the randomized blocks method, with the follwing factors and graduations: A Factor: Water- supply level (A1 unirrigated; A2 – irrigated with pedological norm of 700 m3/ ha; A3- irrigated with 50% reduced pedological norm = 350 m3/ ha;B Factor: The hybrid (FAVORIT, SINGI, DELFI, PR64A89, TEKNY, KONDI). Results: 2011 proved to be a favourable one for the sunflower crop.The obtained yield while using the sunflower hybrids was influenced by the water – supply level, the average being 42,0 q /ha in unirrigated conditions, 50,4 q/ha taking into account the pedological norm of 700 m3/ha and 45,7 q /ha, with50% reduced the pedological norm. Conclusions: The classification of hybrids after the obtained yield in different water- supply conditions is: Singi, Kondi, Tekny, Favorit, Delfi and PR 64A89. The average seed- weight per head, 1000 – seed weight and the hectolitric mass varied in terms of the hybrid and the water- supply level.

The paper aims to present the early stages in the implementation of a Geographic Information System in the field of archaeology and its advantages. This field uses the spatial information in the required activities, whether in research or management. The chosen area of study is located in the West part of Galați City. We used as support data the orthophotoplans of that area, produced by National Agency for Cadastre and Land Registration, a topographical map produced by D.T.M, sets of photographs of archaeological sites in the area, taken from the helicopter and a LiDAR dataset for the archaeological site from “Bărboși”.I wanted to highlight the placement of these objectives in the area of study and to present the potential that LiDAR technology has in archaeology. For this I drew up a situation plan based on the digitised data, I realised a Digital Terrain Model using contours and points of known elevation from the topographic map. I generated a Digital Terrain Model based on LiDAR data, for archaeological site from “Bărboși” and I showed a few of the analysis possibilities on the basis of this model.

The paper presents some aspects concerning two ecological rehabilitation projects that were partly implemented by WWF International – Danube Carpathian Programme within the Lower Prut River Basin region, in the period of years 2003-2006: Elan/Prut River Basin in Romania, respectively “Lower Prut” Scientific Reserve, in Moldova. The Prut River is one of the main tributaries of Danube River and it forms the border between Romania and Moldova, in South-Eastern part of Europe. The Lower Prut floodplain in Moldova, with a total surface of 19,125 ha, contains about 6,114 ha of wetland habitats which are officially designated under the Ramsar Convention as being a Wetland of International Importance. The floodplain has also a regional importance due to presence of an impressive list of rare and threatened species of flora and fauna, including herons, egrets, cormorants, storks, swans and the globally threatened White pelican, as well as for flood control, nutrients and sediment mitigation and groundwater recharge. The site contains the largest natural lakes in Moldova, Beleu and Manta, which are unique ecosystems, described by some scientists as being part of the last natural floodplains in the Lower Danube River. Being aware by the global importance of these wetlands, the Moldavian Government has created in 1991 the Lower Prut Scientific Reserve, located at the lower stretch of the river to its confluence with the Danube. The Reserve, with a total surface of 1,691 ha, is covered by about two thirds by lake and one third is represented by alluvial forests (mainly willows). The main purpose of creating the Reserve was to protect the valuable ecosystems mentioned above. The Reserve is also an important component of the biggest freshwater programme in the region, called Lower Danube Green Corridor (LDGC). The LDGC declaration, signed in 2000 in Bucharest, between Romania, Bulgaria, Ukraine and Moldova, aims to help creation an integrated ecological network of healthy, restored and protected wetlands, of about 900,000 ha along the Lower Danube River and to promote sustainable socio-economic development in the area.
