CONSIDERATIONS ON OWNERSHIP AND OWNERSHIP OF FORESTS
Get PDFProperty is the foundation of any legal system. The history of every human society, in any geographical space, has emerged, is born and verticizes by property.The legal institution, called "property," is a special social reality, fundamental to any community, being unanimously recognized that property ownership is the most important of man's real rights.Occurred with the very appearance of man on earth, property stood and is at the basis of the development of human society, representing one of the fundamental problems of individual existence and of human society.Property could not remain outside the scope of the law because it is the premise of any economic activity, that is, the premise of the operation of the engine of any society, and the purpose of the law is precisely to organize and ensure the proper functioning of society
INFLUENCE OF THERMAL AND HYDROSTATIC STRUCTURE ON GROWTH PRODUCTION TO WHEAT AND MAIZE IN THE CARACAL FIELD
Get PDFIn this paper an analysis of the complex influence of the agroclimatic resource variability on the vegetation state and yields on the autumn and maize wheat field crops in the Caracal Plain is carried out for a period of 3 years during the whole autumn wheat and maize vegetation season, the agrometeorological conditions varied significantly from one agricultural year to another depending on the evolution of the agrometeorological parameters on specific phases of plant growth and development.The amount of precipitation and its distribution over months and critical vegetation intervals varies from year to year compared to the optimum limits specific to each month, season or agricultural year as a whole, significant negative deviations from them, causes unfavorable conditions for growth and development of plants during vegetation with influence on production.The combined and lasting action of the agrometeorological parameters of thermal and hydrological stress, respectively the days with maximum temperatures in the air that frequently exceed the critical biological threshold associated with insufficient precipitation (<10 l / mp / month), led to a significant decrease of the soil water reserves up to the values that characterize the occurrence of the pedological drought with varying degrees of intensity, the level of crops thus being in obvious correlation with their evolution and duration
STUDY ON THE ORWING REGIME OF THERMAL MOTORS OF AGRICULTURAL TRACTORS
Get PDFMotor vehicle rating parameters are expressed using features that are graphical representations of sizes that make it possible to compare with other similar engines and establish behavior in service. For motor vehicle dynamics, the engine speed or external characteristic speed characteristic is used, which represents the actual power variation curve and the actual moment depending on the engine speed or angular speed. At present, standards on engine testing methods vary from country to country, with regard to no. engine mounts during the tests, the volume of test work and the working conditions. As a result, for one and the same engine, it is possible to obtain different speed and load characteristics, depending on the standard or the tests performed.It has been found that the increase in the speed above the maximum allowable value, the engine power is considerably reduced due to the worsening of the filling of the cylinders with the fuel mixture and the mechanical losses in the motor. For these reasons and in order to avoid the high dynamic loads it is recommended that at maximum speed the displacement max. do not exceed the maximum power speed by 10 ... 20%
TECHNOLOGICAL AND ECOLOGICAL ASPECTS OF SOME WINE WASTE RECYCLING AND THEIR CAPITALIZATION IN FOOD INDUSTRY
Get PDFThe wine waste management aspect is very important for small and industrial wine producers from technologic, ecologic and legal aspect. The most important reason for the wine producers on the market is the legal one because, it has multiple implications at national level (economic, technological, ecological and food) if it has branch in Romania and also international, if the producer wishes to play on European and international market. Analyzing the actual legislation, in this paper will pe presented an innovative technology to capitalize some wine wastes, namely the marc byproduct, to be used in the food industry as raw material for high value phytopharmaceutical compounds. In this way is presented an alternative to recycle the wine technologic waste, to reduce the business ecological impact on the environment and to apply circular economic marketing strategies
CONSIDERATIONS REGARDING THE HARVESTING TECHNOLOGIES OF JERUSALEM ARTICHOKE
Get PDFJerusalem artichoke (Helianthus tuberosusL.) is not cultivated on the large surface that cereals, vegetables or potatoes so mechanizes technologies are not very often encountered. In this paper are presented few technologies used on the country where this culture occupied large surface and not only
STUDIES ON THE IMPLEMENTATION OF THE SUPPORT PROGRAM FOR TOMATOES IN PROTECTED SPACES IN 2017 AT THE COUNTY OF DOLJ
Get PDFIn order to support vegetable growers, the Ministry of Agriculture and Rural Development initiated in 2017 the "Program of support for tomato producers in protected areas", in which the owners of at least 1000 m2 of solariums, which marketed the production of at least 2000 kg during January - 15 June, and / or 23 October - 20 December, received from the state the sum of 3000 euros. In 2017, at the level of Dolj county, 620 vegetable growers benefited from the provisions of the tomato product support program in protected areas, the area of tomatoes cultivated in the solariums being of 74,83 ha. From centralized statistical data at the Dolj County Department of Agriculture, the area cultivated with tomatoes in solariums in the year 2017 was 125 hectares, resulting in the Program's share of the tomato area being 59,86% of the total area. Regarding the cultivars used, there is a wide diversity, 620 vegetable growers cultivating 91 cultivars, 96% hybrids, but also varieties and even local populations. In the hierarchy of varieties, predominates the Bulgarian hybrid Prekos F1, which cultivated in the area of 31,88 ha (42,60%)
ECOLOGICAL RECONSTRUCTION THROUGH AFFORESTATION WORKS OF THE JILT DUMP HAVING AN AREA OF 10 HA, LOCATED IN THE MIDDLE BASIN OF JILT RESULTED THROUGH SURFACE MINING
Get PDFThrough the research undertaken on the present subject it aimed the scientific groundwork of the ecological reconstruction of the dump resulted through surface minings located in the middle basin of Jilt and the choice of afforestation technical solutions using the forest vegetation. This scientific groundwork follows the way to achieve the dumps and their current morphology, as well as the mineralogical and particle size, physical, hydrophysical and chemical composition of these dumps, factors underlying the characteristics of the composed technosoils and the choice of the species, formulae and of the afforestation schemata. Also, the groundwork aims the harmonization of the ecological requirements of the used wood species with the dump soil characteristics.The preparation technology of the dumps in order to afforestation is relatively simple and it requires a rest period after the release from the technological changes, to strengthening and stabilization, followed by a microlevelling and then the artificial ingrass on the sectors  where it was not naturally installed. To establish the species used in afforestation works and the way of installation of the forest vegetation on the taken dumps, it were taken into account aspects specific to the site conditions.Forest promotes the storage of water on slopes, by preventing the formation of the surface runoffs and of the flood waters, following the heavy rains and the snowmelt, thus counteracting the flood phenomena and soil erosion. The establishment of the forest plantations aims the slope stabilization and the development of some forests with multiple role: the protection of the environment by regulating the climate and the hydrological regime and by creating parks and recreation places of favorable habitats for wildlife and protective role.Outstanding results on afforestation of the Jilt dump presented: sea buckthorn, black locust, poplar and walnut, these species will be used for the stabilization of the future dumps.Less well results presented species of Quercus (sessile oak, Turkey oak, pedunculate oak, red oak), pine, hazel
UTILIZATION OF TOTAL STATIONS IN THE WORK OF DETACHMENT A PROPERTY
Get PDFThe detachment of a property is common in recent years, primarily due to the modification of the urban plans, by the extension of the urban areas to the detriment of the arable lands. Thus, there is the possibility of lotizing larger terrains of the order of thousands of square meters in several plots of different sizes, generally 250-600 m2, which are then sold for the construction of new dwellings. In the paper is presented as a case study such a detachment of a property, using for field measurements the total station
RESEARCH ON THE COMBINED USE OF GPS - TOTAL STATION SURVEYING TECHNOLOGIES IN CADASTRAL AND ENGINEERING WORKS
Get PDFDuring the period 2015 – 2023, extensive national works are being carried out within the framework of the National Cadastre and Land Book Plan (PNCCF). In view of this, the research team from the Faculty of Agronomy in Craiova tried to achieve a simple, rapid and accurate procedure for terrain surveying with modern methods, using total station and GPS technology. The use of a total station was necessary since, even if topo-geodetic surveys performed with a GPS are faster and yield greater return, engineering works necessitate a high precision, which can only be fulfilled by combining the two technologies. It also made possible to verify the precision when determining new points in the support network built for this case. In order to achieve the proposed objectives, a complex building with a more complex composition from Craiova was studied, topo-cadastral elevations being accomplished using high-precision equipment, the efficiency of a total station (Trimble S6 servo) and GPS (Trimble R10), which from a technical point of view enabled us to achieve the best results in the most rigorous of cadastral works, carried out at a national or even international level. The results obtained from the methods and technologies, applied both on the ground and in the office work, as well as the calculation of the coordinates and the support network compensation are very relevant, precise and with high efficiency, making the proposed solutions to be of a real interest for terrestrial measurement experts at the local, national or even international level
