Economic Efficiency of Irrigation Regime of Tomatoes and Cucumbers Crops Cultivated in Of Protected Areas

Irrigation is the method to cover the soil water deficit for the benefit of agriculturalproduction. It took different forms in time and space, both in terms of concepts and one of the methodsof application. The main goal of our research is to determine whether the furrow or drip watering atdifferent times of onset of splashing. Irrigation by furrows lead to the achievement of higher waterconsumption, but may be, in some cases, a key element in achieving higher production by theadministration of large quantities of water. Lower production obtained in the case of drip wateringmay have economic justification, because the water was more efficiently valued on the plant. As aresult, the farmer is often placed in a dilemma: it is preferable to obtain smaller quantities of fruit withlower water consumption or to obtain higher yields, even in the conditions that the water taken in largequantities can lead to diseases

Review for Soil with Excess Moisture

Soil is one of the natural factors representing the environment over which occurs during the process of watering and acts as a "reservoir" of water storage. Soil is a porous medium that cannot hold a lasting only a certain amount of water, excess water either through ground water seepage and moisten the lower strata either be retained on the surface water ponding. Excess moisture temporary or periodic: Prolonged excessive wetting, wetting the medium term, the short wetting, wetting of varying duration (short-extended). After excess moisture source and intensity:  moderate excess ground moisture; strong excess ground moisture; overate excess moisture from precipitation; strong excess moisture from precipitation; excess moisture from precipitation under phreatic intake; excessive humidity combined: groundwater and precipitation; excessive humidity in coastal streams; flood excess moisture; excess of moisture and salts. Heavy rainfall produces excessive humidity in cool areas where evapotranspiration is low and with low soil permeability. Depression relief favors the appearance of excess moisture in the rainy season on clay-rich soils. Low renewal of the air in the soil results in the accumulation of large amounts of CO2, the CO2 content of the air in the soil than 1% by plants suffer. Excess moisture causes reduced soil aeration, slowing oxidation and mineralization grading the pharmaceutical insufficient debris. Remove excess moisture by means of a network of drainage channels, as compared with the removal of excess moisture by a network of open channels, has a number of advantages, such as small area removed from the culture, ease of agricultural works by mechanical means, simple maintenance work, lack of widespread outbreaks of weeds, pests and diseases etc. The disadvantage is the high cost of pipes, drainage filter material and execution

Importance of Topographic Works in the Real Estate Assessment

Property valuation is an area that has taken off in recent years, because worldwide, eachperson uses the property for which they paid a certain amount to purchase. Evaluation on establishinga value to help the buyer, who must establish a purchase price, or to help the seller, the person who hasto establish a sale price. Another reason assessment evaluation is carried out is to establish a value forthe calculation of taxes. In this area, the surveyors are increasingly asked to carry out measurements toestablish property limits for the determination of areas, because these data is needed in the valuationprocess, the assessor must make a confrontation between data obtained from the owners with dataobtained from topographic measurements

Researches Concerning the Dynamics of some Physical-Chemical Modifications in First Quality Beef during the Salting and Tendering Process

Twenty-five samples of beef semi-manufactured products (minced and salted beef, in different stages of tendering process) used in the manufacturing process of some meat products in casings have been organoleptical and physical-chemical examined. During the salting and tendering process a pH increase can be noticed, total and protein nitrogen decreases proportionally with the proteolytic degree, respectively, the degree of ageing of meat.The quantity of water and nitrites decreases while the salt content increases proportionally with the water content decrease.These values limit the period of the tendering process at maximum 72 hours, the optimum period being considered at 48 hours, at the storage conditions: +2…+4 Celsius degrees

The Result of Inappropriate Farming Practices on the Quality of Sandy Soils on South Oltenia

The paper was realised having as departure point the map of soils from the South of Oltenia, processed with the aid of SIG. The South area of district Dolj, though its geographical position it is situated under the influence of an excessive natural ground with annual average temperatures that are high enough, average annual precipitation of 400-500 mm and the value of the small aridity index is considered to be one of the most predisposed areas at the process of soil degradation due to drought phenomenon of drought - aridity - desert. Work of improvement and preservation of the soils must be advisable realised

Quantitative Determination of Organochlorine Pesticides Residues in Raw Milk Used for Scalded Paste Cheese Production

The aim of the study was to determine the level of organochlorine pesticides residues in raw milk samples collected from five units of cheese production. The determined organochlorine pesticides were α-HCH, β-HCH and γ-HCH (Lindan).Â

Quantitative Estimates of Sediment Deposited

Soil (ground) is for people amid social and economic activities, natural resource invaluable, the most precious wealth of a nation. From this point of view, Romania has a great wealth, especially given balanced structure planning: third area of forests, meadows third of hills, orchards and vineyards and third lowland land where farming takes place. Preventing soil erosion requires measures imposed by climatic characteristics of the area and socio-economic status, medium and long term actions to improve the situation of soil, which can then be combined nationwide to save and to ensure rational use and exploitation and sustainable land it holds Romania, regardless of land ownership

Surface Erosion Estimations Using Universal Soil Erosion Equation (USLE) Regarding Terrain Revegetation

Depending on the amount allowable soil losses can be used to establish strategies for choosing cultural structures and their relationship, their share in a crop rotation with very good, good or poor soil protection. Following heavy rains, leaks occur as a rolled canvas spread over the land surface. Following leakage of these processes, with streams of water are entrained soil particles and moved longer distances or smaller. Following this process, after a time, depending on the frequency and duration of heavy rains that generate surface runoff, finally, lead to total washing humus accumulation horizons and finally reach the parent rock or rock foundation. Under the indirect method (Universal Soil Erosion Equation of conditions in Romania) has determined that the surfaces covered with forest, located on a slope of between 5-10% slope and slope length of steepest slope below 100 m, recorded an annual loss of 0.0067 t · ha-1, respectively on a slope with the largest slope length greater than 100 m is estimated annual quantity of 00.0058 t · ha-1. To identify risk areas for soil erosion is necessary to set limit values ​​of tolerance levels and set the type of soil and its characteristics, except that vary from region to region and depending on the type coated surface of the land

Researches Regarding the Level of Organophosphoric Pesticides Residues in Raw Milk Used for Scalded Paste Cheese Production

The aim of the research was to establish the level of organochlorine pesticides residues (αHCH, β-HCH, γ-HCH (Lindan), DDT-T, Heptaclor, Dieldrin, Endrin) in the raw milk used for cheese production. Sixty samples of milk were analyzed, using the gas-chromatographic method from AOAC (Association of Official Analytical Chemists). Thus, the pesticides residues from milk fat or from the ether extract of the sample were selectively extracted with acetonitril and petroleum ether and purified on florisil column and than eluted with petroleum ether, diethyl ether and ethanol mixture.Â
