ECONOMIC EFFICIENCY OF MAIN SOIL TYPES FROM BÂRZAVA PLAIN FOR WHEAT AND CORN CROPS

This paper represents an economic study of the main soil types in Plain Bârzava forwheat and corn. Studying the economic efficiency of soil is important because according to it we can draw conclusions about the effectiveness and profitability of crops.Knowing evaluation notes I could find natural production potential of soils that wheat and corn crops by multiplying the grade of evaluation with 60 kg / point for wheat and 75 kg / point to corn.Economic comparison was obtained by multiplying production by 0.7 lei / kg forwheat crop and 0.8 lei / kg for corn, amounts representing the price / kg practiced in the summer of 2011

DEGRADATION OF AGRICULTURAL LANDS CAUSED BY EROSION (CASE STUDY, VERMES COMMUNE, CARAS-SEVERIN COUNTY)

Soil erosion is the washing process of the genetic horizons of soil rich in humus and of nutritive elements important for plant development, appearing on sloped surfaces by water action, followed by downhill sedimentation or sedimentation in water courses which carry these materials in lakes and seas. Thus, the sloped soils remain exposed to erosion and degradation processes.Because of land cultivation by inappropriate technologies, the quality of soilsdecreases and these are exposed to degradation of physical and chemical properties of horizon A and of subsequent others. Of course, this phenomenon is not immediately, its intensity and amplitude depends on anthropic factor (human activity), one of the most important factors, sometimes with disastrous consequences.Territory is affected by surface erosion with different intensities, and partially was observed landslide, especially at the origin of erosion valleys. The surface affected by erosion with different intensities is approximately by 11,5%

LAND EVALUATION FOR DIFFERENT CULTURES, THE CITY RECAS TIMIS COUNTY

The total area of 23,198 ha is Recaş village.When taken in culture and fertilized soils shows an enrichment of cations basics.Agricultural use as arable land is constrained cups increased Lift temporarily poor because of their compactness or submitted.To improve a number of interventions are necessary agrotechnical and agrochemical: the moldboard plowing to alleviate temporary excess humidity, calcareous amendments correct reaction conditions, organic fertilizers to increase reserves of humus and fertilizers. Due to excessive rainfall and high humidity plants are not optimal development.State nutrient supply is poor and existing reserves are mobilized difficult becauseair-fluid system losses and poor microbiological activities

THE SOILS STUDY IN AVRAM IANCU COMMUNE PERIMETER, ALBA COUNTY

The village is located in the depression formed by the upper course of Arieșul Mic46022' north latitude and 22049' east longitude with an altitude of 750 m is surrounded by mountains Biharia in NV, Mount Gaina part of V, and Muntele Mare in the NV. Soil studies and research synthesis that large areas of land are affected by one or more limiting factors and/or restrictive agricultural production.Physical soil has a loamy texture and bulk density increased with control conditionsaerohydric regime. Agrochemical soil is moderately debazificated acid, following the limits concerned in correcting soil and protection of the reaction (pH). Has an average supply of humus, probably due to the application in the area exclusively manure. Soil fertility and productivity is low

THE SOILS STUDY IN LENAUHEIM COMMUNE PERIMETER, TIMIŞ COUNTY

From the geomorphological point of view Lenauhein commune territory is situated inthe great unit of relief of Banato - Crişana plain, specially in Nordic Banat plain on Galaţca – Beregsău interfluve.Characteristic for the forest steppe area, natural vegetation in commune territory has been replaced, in a large measuring tool, by agricultural cropsMorphological characterization of the major physical and chemical soil typesaccurately depict current status for the supply of their products with the most important nutrients: humus, nitrogen, phosphorus and potassium. So by analyzes carried out it has been found that the best physico-chemical properties soil is Chernozemic soil

RESEARCH ON THE SOIL OF SUITABILITY RECAS GROWING CENTER

Viticulture is a branch of agriculture with a high intensity level, vines involves energy consumption, it can not develop without energy or low intake of it. Increased production WINE will take place in future energy crisis and raw materials (Ţărău D., Luca M., 2002, et Țărău D., Borza I., Dumitru M., Ciobanu C., 2007) .Objectives aimed especially following: identification and characterization of soiltypes and subtypes, calculating evaluation notes, determining suitability and land classification in classes of favorability. Recas vineyard soils Center, formed by the complex interaction of factors of which the most important pedogenetic are topography, water, rock parent, climate, vegetation and man. Thus the perimeter Recas are two areas where soils are well differentiated, a result of different climatic conditions

PRESENTATION OF THE HYDRIC AND CHEMICAL INDICES OF THE MAIN TYPES OF SOIL IN RECAS VITICULTURE CENTRE, TIMIS COUNTY

In order to reach the aim of this paper, we established the following objectives thatwe researched in the field and in the laboratory: identification of the soils and of soil units and land units morphological, physical and chemical characterization of the main types of soil,We made use of several research methods that are specific for pedology: soilmapping, morphological description, expeditive field determinations, laboratory analyses, processing the data referring to soils, etc. Thus, we identified nine genetic types of soil in the perimeter under research, after direct observations made recently in the field and processed in the laborator

SUITABILITY FAVORABILITY SOIL AND THE CITY OF PERIMETER FAGET, TIMIS COUNTY FOR MAJOR CROPS AGRICULTURAL AND HORTICULTURAL

The Făget city is located in the south-western Romania, in the contact area of theHills Plain Lugoj the upper Bega River.Plain occupies about half the land area is investigated and the lowest level morphology with hypsometric values between 75 and 200 mIn general, agricultural land is conditional evaluation of knowledge of the complex operation of breeding and fruit-bearing plants and to determine the degree of favorability of these conditions for each use and culture (as can be adversely land for certain crops and agricultural uses and favorable for others), through an index system of evaluation techniques and notes.The main types and subtypes of soils in the urban area Făget are: Regosoil,Luvisoil stagnated Luvisoil white, Gleiosolil typical, eutric

SUITABILITY OF SOILS REMETEA MARE, TIMIS COUNTY

Soils studied area formed by the complex interaction of factors of which the mostimportant pedogenetic are: landscape, water, rock parent, climate, vegetation, man. Thus the investigated area are two areas where soils are well differentiated, a result of different pedogenetic conditions.In the high plains and hilly area on the material more or less reddish carbonateformed and evolved preluvisols mollic typical.Mineralization because most parts of the debris that is deposited annually in the topsoil to form a small amount of humus and therefore higher horizon color is brown (Ao), met frequently with preluvisols horizon

THE AGRICULTURAL SYSTEM IN BEBA VECHE, TIMIŞ COUNTY

Beba Veche is a locality in Timiş County. Its coordinates in what latitude isconcerned are 46° 7' 60 north, 20° 19' east. It lies 81 m above sea level. It is the most western locality in Romania, situated at the border with Serbia and Hungary. The archaeological discoveries made here attest the millenary existence of the locality( Ţărău D., Luca M., 2002).The agricultural land of the commune is composed of the following: arable 7.767 ha, pastures 976 ha, hay land 3 ha, vineyard 16 ha and orchard 30 ha. As for the fertility classes, for the "arable" land the situation is the following: 1st class 804 ha (9.3%), 2nd class 2193 ha (25.5%), 3rd class 2755 ha (31.9%), 4th class 2777 ha (32.2%) and 5th class 98 ha (1.1%). The limiting factors that influence land quality in this area are represented by the phenomenon of severe salinization (salinization on 6.3% and alkalisation on 34.5% of the surface), low humus content (0.82%).
