Magdaléna Lacko-Bartošová, Joanna Korczyk-Szabó

The aim of this research work was to evaluate the quantitative and qualitative parameters of winter wheat cultivated in ecological (ES) and integrated (IS) farming systems. Farming systems were established in fall of 1990 at a research base near Nitra in South Slovakia region on brown clay loamy soil. The experimental field altitude is 178 m., average year temperature was 10.4ºC and average annual precipitations was 582 mm. The chemical inputs of integrated system were replaced by multifunctional crop rotation, ecological plant nutrients, mechanical and physical weed control and optimal soil cultivation in ecological system. In the 2005-2007 the effect of two different farming systems (ecological and integrated ) and two levels of fertilization on qualitative parameters of winter wheat were observed. Year of farming had highest influence on production parameters. Falling number and wet gluten had been influence by year of farming, fertilization and system of farming. Fertilization and system of farming did not have any significant influence on gluten index.

AGRICULTURAL USE OF SEWAGE SLUDGE PROS AND CONS pag. 15-20

Adina Berbecea, Isidora Radulov, Florin Sala

Sewage sludge, also referred as biosolids, is a byproduct of sewage treatment process. Land application of sewage sludge is one of the important disposal alternatives. Characteristics of sewage sludge depend upon the quality of sewage and type of treatment process followed. Being rich in organic and inorganic plant nutrients, sewage sludge may substitute for fertilizer, but available of potential toxic metals often restricts its uses. Sludge amendment to the soil modifies its physico-chemical and biological properties. Bioavailability of metals increases in sludge amended soils at excessive rates of application for many years. Plants differ in their abilities to absorb heavy metals from sludge applied on the soil. The aim of the paper is to review the available information on various aspects of sewage sludge application on soil fertility and consequence effects on plant production to explore the possibilities of exploiting this byproduct in agriculture.

CLAY MINERALS IMPACT UPON SOME MICROORGANISM POPULATION OF SOIL pag. 45-50

Constantin Crăciun, Marius Eftene, Victoria Mocanu, Sorina Dumitru

The paper is an attempt of quantification of clay minerals influence upon the population of certain groups of micro organisms from soil. The aim of this paper is to verify and to validate the earlier established relationships between soil biological and mineralogical parameters in a context of qualitatively and quantitatively extended pedological information. The obtained results confirm to a great extent the former ones. Thus, the established relationships between biological and mineralogical parameters indicate that the bacteria and fungus number are closer related to the clay quality than to its quantity. The same relationships show that between the soil biological indicators and clay iolite content there is a direct linear relation, while between the same biological parameters and the clay smectite content this linear relation is inversed. The confirmation of these relationships on statistical basis, using results of physical and chemical determinations, becomes more difficult when the number and complexity of the considered situations are increased.

The field experiment was conducted on Luvi-Haplic Chernozem with loamy to clay-loamy texture and humus content of 1.8-2% in maize growing region in south-west of Slovakia. The aim of the research was the time and space evaluation of bulk density dynamics in conditions of the no-till system and the mouldboard ploughing. Soil samples for measuring the soil bulk density were always taken in the spring term (March-April), after the crops harvest in the summer term July-August except for the maize and mostly in September and October in the autumn term at the three soil layer 0.0-0.10; 0.10-0.20 and 0.20-0.30 m. A positive correlation between the soil bulk density and amount of rainfalls in the period from spring to summer was determined. In comparison with the mouldboard ploughing, soil in the no-till system was mellower in all layers. Relative differences at measured figures of the average SBDr between the tillage systems with regard to the depth of soil were the highest in the upper layer and were gradually reduced towards the depth. The biggest difference of the soil bulk density was recorded in summer. The differences were reduced from summer to autumn and they approached the figures measured in the spring season. The reduced soil bulk density was mostly influenced by weather, date and depth of sampling as well as the tillage system.

The exact appreciation of the soils degradation state, by the erosion and associated processes, is an operation that involves high costs and a long time for observations, determinations and measurements. It also requires a geographic informational system that allows to identify the spatial dates and to compare these dates and the interpretation of theses are made through analytical methods. In Romania, the intensity of the soil erosion on the agricultural lands is very high; annual 106 mil to/year of soil are lost. In Bistra Hydrographic area the surface erosion is caused by the improper usages of the lands and by the excessive grazing.

Like nitrogen and phosphorus, potassium is major nutrition`s element contributing to large, steady and high quality crops. Crops need potassium and nitrogen in fairly comparable amounts however everyday agriculture stands proof to a lack of balance in the intake of these nutrients to the detriment of the potassium. The potassium used in fertilizers, especially in developing countries, is much below the amount of the potassium in the crops. By way of consequence the amount of the potassium in the soil diminishes and so does soil fertility.

Soil enzyme activities (actual and potential dehydrogenizing, catalase, acid and alkaline phosphatase) were determined in the 0–10, 10–20, and 20–30 cm layers of a preluvosoil submitted to a complex fertilization experiment with different types of green manure. It was found that each activity decreased with increasing sampling depth. It should be emphasized that green-manuring of maize led to a significant increase in each of the five enzymatic activities determined. The enzymatic indicators of soil quality calculated from the values of enzymatic activities showed the order: lupinus + rape + oat > lupinus > vetch + oat + ryegrass > lupinus + oat > rape + lupinus >rape > unfertilized plot. This order means that by determination of enzymatic activities valuable information can be obtained regarding fertility status of soils. There were significant correlations of soil enzyme activities with physical and chemical properties.

The paper is based on the researches carried out in an experiment set up in 1990 in Oradea, on a preluvosoil. The experience has two factors – factor A is crop rotation (a1 – wheat monocrop, a2 – wheat, maize; a3 – wheat – maize - soybean) and the B factor is the water regime (b1 – unirrigated, b2 – irrigated) with maintaining the soil water reserve between the easily available water content and field capacity on watering depth (0 – 50cm). The researches carried out between 2005 – 2007 have shown the smallest of the gross protein content, wet gluten, dry gluten, deformation index and fall index registered in the wheat monocrop. In the wheat-maize crop rotation the values of the quality indexes have improved, the differences were statistically assured. The biggest values of these indexes were obtained in the wheat – maize – soybean crop rotation, the differences when reported to monocrop being very significant in all the studied years, in the conditions in which, in the durable agricultural system is the central pivot, and the researches carried out show the importance of the crop rotation with a large number of plots and the importance of the soybean crop as a forerunner for wheat, it’s effects being positive on the both on the quantity and the quality of the wheat yield, as well as the protein, dry gluten, wet gluten content, fall index and the deformation index.

The paper is based on the decadal determinations of the soil moisture and the dynamics graphs of the soil water reserve on the watering depth. These show the decrease of the soil water reserve under the easily available water content every year, and in ten years under the wilting point. An inverse correlation between the number of days with pedological drought and maize yield very significant statistically was quantified; a direct correlation between the number of days with drought and the yield gain was also quantified. Irrigation determined an improvement of the conditions of the microclimate (water consumption and water use efficiency). The correlations quantified in the soil – water – plant – atmosphere system sustain the opportunity of maize irrigation the Crisurilor Plane.

The opportunity of the soybean crop irrigation is sustained by researches regarding soil water regime and show that in unirrigated conditions, the water reserve dropped under the easily available water content in every year, thus irrigation was needed in order to ensure a proper water supply. Irrigation determined the improvement of the microclimate conditions and the increase of the consumption levels, and in the end obtaining high yield gains very significant statistically. Direct correlations between the water consumption and the yield and between the climate indicator and the yield are the arguments that sustain the opportunity for irrigation of the soybean crop in the Crisurilor Plane.

F. Gadotti, Cosmin Popescu

The use of a 3D scanner in measurement optimises design, architecture, town planning and cadastre-related activities. The measurement instruments make use of a quick laser and a video camera to capture a large number of points and video images. The 3D images consisting of points can be changed into objects that in turn can be analysed, processed and registered in a database, together with a series of attributes and data. Such applications can be used in the study, the comparative chronological analysis and the inventory of an object, taking into account that for a high resolution either millions or only several points can be captured for high resolution. Also, point density can be selected for objectives like roads, streets, bridges or tunnels, where distances vary.

THE USE OF THE MERCATOR PROJECTIONS INTO THE CARTOGRAPHICAL REPRESENTATIONS pag. 313-320

Octavian Herbei, Artur Ursu

In general, the existent topographical maps of the Romanian territory are made by using on of the systems of cartographical projections: Stereographical projection – 1970, Gauss-Krüger or UTM (Universal Transversal Mercator). Each of these systems of cartographical projections has advantages and also disadvantages. One of the basic criteria in using a cartographical projection for a certain cadastral territory is that the relative linear deformation should be as small for that geographical area. The maps from the UTM projection have a great importance in the sea navigation and in the air navigation, because it is a conform projection, and the cartographical network is made from perpendicular lines, plain will be a right line. The same line makes with each of the meridians projection the same azimuth.

TECHNOLOGICAL AND CALCULUS ASPECTS OF ANCHORED FOUNDATIONS APPLICABLE TO SPECIAL CONSTRUCTIONS pag. 349-356

Carmen Aurelia Peptan, Virgil Haida, Gheorghiţa Peptan, Floarea Maria Brebu

The procedure of anchorages with pretensioned tie bars creates the possibility of solving some foundation problems that in other solutions would be extremely expensive or impracticable from practical point of view. Anchorages are used at a series of foundation works in the domain of civil, industrial and agricultural constructions (anchoraging some cantilever constructions and some special roof types) and as much for the hydrotechnical constructions. Considering the great number of pretensioned anchorages achieved up to now for a great number of foundations and embankments works, the knowledge about their behaviour is still incomplete. These happen not because there are missing some measurements at natural scale, but because of relatively reduced possibilities of understanding the earth behaviour by its properties in the process of tensioning tie bars, in execution phase, but mainly during their operation in time. Conception and comprising of different types of anchorages or tie bars are not based on calculus, but more on intuition and palpable experiments on site, after that the improving of site technologies is done in general, by the practitioners.

Choosing the type of structure and foundation appropriate to soil category on which is located the construction, is one of the hardest problem of structural engineering. The interaction between structure - foundation - soil (ISFS) represents the behaviour and respond way at the loads of ensemble construction-soil, considered as a unity, compound from constituent parts that have different geometrical and mechanical characteristics and between there exists a continuous process of redistribution of efforts during the progressive increasing of unequal settlement of supports, till the final values. The great variety of constructions structures, geotechnical properties of soils foundations, as many factors and parameters that interfere, it makes the results obtained by classical methods not to present satisfying correspondence between the theoretical an practical results. Hence, it results the conclusion that it’s necessary to give a particular importance of theoretical and practical determination of parameters and factors that interfere in an inter-working calculus.

MECHANICAL MODEL OF THE HUMAN BODY SITTING ON A TRACTOR CHAIR pag. 453-458

Radu Ilea, Cornelia Tonea

The elaboration of the mechanical model of human body sitting on a tractor chair needs the knowledge of the elastic and mass characteristic of the body. The complexity of the human body structure, as well the response of human organism or of different parts to external actions, needs more simplifications for obtain the human body model sitting on a chair or a vibrant platform. For the estimation of mechanical model parameters representing the human body sitting on a vibrant platform it is developed a program for calculus

A NEW THEORY REGARDING THE VEGETAL MATTER DISPLACEMENT ON SHAKER STRAW WALKERS DISPOSED ON TWO AXES AT CONVENTIONAL CEREAL HARVESTING COMBINES pag. 459-465

Gheorghe Ivan, Simion Popescu

The conventional harvesting combines for cereal comprise a shaker aiming (straw walkers) to separate the seeds out of straws coming from the threshing apparatus. The working capacities of the straw walkers and implicitly of harvesting combine depend on the configuration and kinematics regime of shaker. Within the following paper a new theory of straw displacement on the shaker is presented. This theory is decisive for manufacturing a performing shaker.

HEAT PUMPS INSTALLATION FOR HEATING-COOLING THE WATER FROM RE-CIRCULATING AQUATIC SYSTEMS pag. 489-496

Augustin Pop, Petru David, Valentin Popovici, Dorel Lazu

The efficiency of aquaculture practiced in recirculation system types depends by more than one factor, among which the most important is the energetic consumption of the system. To assure a high grade of energy conservation in an aquatic recirculation system, it must be maximized the water recirculation grade and impose the utilization of some unconventional energy sources for heating, respective cooling the water. For this purpose the optimum solution is using an installation for heating/cooling the water with heat pumps.
