15 Romanian brands of mineral water were purchased from hypermarket. For each of the 15 mineral waters were determined the content of nitrates, nitrites and pH. The data obtained were compared with the content of nitrates, nitrites and pH of the tap water collected in 15 locations in Bucharest, according to data released by the Apa Nova operator. The results showed that the mean of tap water pH in Bucharest, although slightly higher than the tested mineral waters pH, did not differ significantly from the mean of mineral waters pH, being situated in the alkaline domain. The mean content of nitrates in tap water in Bucharest, did not differ significantly from that of the tested mineral waters (t = 0.811). Nitrates content of tap water in Bucharest was significantly distinct less, as the pH was higher (r = 0.68**). Basically, the change in pH by one unit, lowers the amount of nitrate by 46%. Bucharest tap water nitrites content was significantly lower than that of tested mineral waters (0.005 mg/l to 0.0124; t = 2.674*). Basically, Bucharest tap water contained up to 2.5 times less nitrites than the nitrites mean of tested mineral waters.

Quantifying the best possible the nitrification of nitrogen in the soil remains an important issue for the sustainable agriculture and for the environmental protection. The aim of the study was to evaluate in the laboratory the influence of some factors: temperature, humidity and amount of manure incorporated in the process of nitrification in a soil mainly in Călăraşi county, on a cambic chernozem. The results of the laboratory analyses were statistically processed by the analysis of variation. In the experimental model, the nitrogen dose increase, given to the soil, had no effect on the nitrification capacity. However, the humidity of 100 % nitrification was stimulated even in the case of the sample test, which has not received the ammonium nitrate. Such an observation could be the basis of the observation that in the irrigated fields, the processes of mineralization of organic substance are always high, especially at high doses of mineral fertilizer. It was noticed that the nitrification process was subject to a seasonal dynamics. The nitrification is more intense in autumn, when the conditions are optimal for this process. As a conclusion, the fertilization system has a great influence on the nitrogen nitrification in the soil.

Bulgaria's membership in the European Union defines the development of clusters as a key element of the National Strategy for increasing the competitiveness. The role of the clusters becomes especially important at this time because SME do not have the capacity to meet EU requirements and to survive without uniting themselves. Moreover the National Strategy for Vine-wine Sector in Bulgaria stipulates the transformation of the sector in a leading one and securing a decent place of Bulgarian wines on international market which may be succeed through cluster introduction in the sector. In the paper is presented an overview of the initiatives for cluster development in the Bulgarian grape-wine sector and are disclosed the structure and role of cluster participants.

The paper aims at identifying new opportunities for relaunching the Romanian beef consumption, from the domestic demand restructuring perspective, having in view the new Common Agricultural Policy (2014-2020). The research study on the evaluation of comparative aspects of beef consumption in Romania and other countries with similar consumption habits was based on the analysis of technical indicators (herds and meat productions, consumption) and economic indicators (incomes, expenditures), on the basis of information and data provided by the National Institute of Statistics – Tempo-online database, FAOSTAT Agriculture and EUROSTAT. The obtained results feature significant differences, with regard to the food intake/person coming from the Romanian beef consumption, both in quantitative and qualitative terms, compared to the other countries under investigation. The conclusion that can be drawn is that meeting the population’s consumption needs with beef products from the domestic production and the creation of export availabilities, as well as the qualitative improvement of the Romanian consumption represent a main objective, which can be reached only by sectoral policy measures, these measures being already included in the new NRDP.

In contrast to the industry, in the agricultural production process, specific factors intervene, which determine peculiarities in the use of labor, means of production and work items. The specific factors acting in the agricultural production process: land, plants, animals, soil and climate conditions, give special features regarding the development strategy, but also regarding the production processes with the two sides: technological and economical, causing certain features with effects on the methodology of economic analysis. These features of farm profitability analysis were briefly presented in this study.

The increased demand for the pharmaceutical market puts pressure on the wild species which on the other hand need to be protected. Collecting the wild plant species for pharmaceutical purpose may became a threat for the conservation of rare species such as Gentiana lutea which was declared as protected species for Romania since 1977. The purpose of this article was to develop a technology for the cultivation of this species as a crop plant. The starting material may be either seeds either seedlings, each of them involving different negative or positive aspects. The produced rhizomes morphometrically characterized and production were calculated. The entire technological chain is described and it may be considered that Gentiana lutea may become a valuable crop species for producers as well as for the pharmaceutical industry.

In most countries within Europe there are numerous small rural Waste Water Treatment Works (WWTWs) often serving a small number of people equivalents (PEs). It is usually impractical and expensive to upgrade such WWTWs and yet they are often delivering potentially highly polluting effluent into streams and rivers. Short Rotation Coppice (SRC) willow, grown as an energy source, may be an ideal crop for the bioremediation of a variety of effluents and wastewater streams. As part of an EU funded (INTERREG IVA) project called ANSWER (Agricultural Need for Sustainable Willow Effluent Recycling) four Proof of Concept irrigation schemes were established ranging in size from 5 to 15 ha. One of the larger of these at Bridgend, Co. Donegal, Republic of Ireland was planted in spring 2013 and has been irrigated with municipal effluent since June 2014. Over 19,000 m3 of effluent has been applied to the willow thus preventing 617 kg N and 28.5 kg P from being discharged to a neighbouring stream. Using SRC willow for the bioremediation of effluent from small rural WWWTs offers a sustainable, cost-effective and practical solution to wastewater management in many countries. There may be also potential to use willow for the bioremediation of landfill leachates, within the footprint of the landfill site.
