AbstractThe Romanian strategy in the field of irrigations for the years of 2008-2011 consists of the modernization of the existing works covering about 3.1 mil. ha, while for the years of 2011-2025 the irrigation of additional area of 0.9 mil. ha is expected. In the climate conditions of Romania, the irrigation has a complementary character over the precipitations. Because of this reason, a correct regime of irrigations needs a very good correlation between watering and precipitations in order t...

Abstract It's well known the degradation of many Romanian (including Dobrogea) soils, both in hill and in plain environments, due to the increasing anthropic pressure on natural resources. Soil erosion and organic matter loss are recognized as the main processes responsible of such degradation and of the rising risk of desertification, to which land use changes and politics for agriculture not suitable for land specificities often contribute. The knowledge of land use impact on soil quality i...

Abstract The slags are an important waste and by-products of metallurgical industry. The present paper summarizes results obtained from physical and chemical analyses on metallurgical slag provided from S.C. ?Mittal Steel Galati? S.A. The physical structure and gradation of granulated slag depend on the chemical composition of the slag, its temperature at the time of water quenching, and the method of production. The following mineralogical components were noticed through bypowder X-ray diffr...

Abstract The influence of exogenous form of heavy metals intake on their transformation in the soil is determined during model experiments. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is observed. It is established that Cu accumulates mainly in the fraction connected with organic matter; Zn accumulates in...

Abstract In Hungary, 0.5 million m3 of thermal water is exploited every day for diverse purposes. After utilization, this enormous amount of thermal water becomes sewage water with a high concentration of salts, heavy metals, ammonia, nitrate, an unfavorable ion composition and high temperature. A common treatment is to dispose of waste water into a surface recipient through uninsulated channels surrounded by arable land. By infiltration, sewage water can cause potential salinization/sodific...

The accumulated characteristics of typical veterinary antibiotics (tetracyclines, sulfonamides, quinolones and macrolides) and tetracycline resistance (tet) genes in the different wetland soils (Krasnozem and Chernozem), and the effects from Phragmites australis were evaluated in this study. Results indicated that the concentrations of targeted antibiotics and tet genes in soils with swine treatment would increase as time progressed. The tet genes and targeted antibiotics (except sulphonamide...

Intensive cereal crops planted on soils from the Western part of Romania determine, annually, significant losses of essential microelements and macronutrients for plant development from the agricultural soil, which lead to the depletion of such lands. Fly ash (FA) resulted from coal combustion at the CET Timisoara power plant, can be used as supplement to an organic fertilizer, such as manure (M) to restore the balance of micro- and macronutrients, important to obtain healthy cereal crops and hi...
