SOIL RESOURCES EVALUATION FOR ESTABLISHING PRODUCTION CAPACITY OF LANDS OF SC ALCRIST LLC DEVESELU, OLT COUNTY PUBLISHEDLICA TUTI, D. ŢĂRĂU
Information based on soil, environmental factors were established soil resources and productivecapacity of the land of SC ALCRIST LLC Deveselu. The results of this work will be materialized in thethesis entitled Ecopedological foundamentation of cadastral value of agricultural land in the Olt, county.To achieve those objectives were investigated three fields, namely 73, 74, and 75 of the SC ALCRIST LLCDeveselu, opening two main sections, considered sufficient for the area studied, within which werecollected soil samples pedogenetic horizons. The soil samples were labeled and transported to the Officeof Soil and Agrochemical Studies Olt where they were analyzed according to national standards andapproved by the Standards Association of Romania (ASRO). In the case of 2 profiles based oninformation from the land, but also on soil analyzes have identified one type of soil, Chernozemrespectively, with subtype cambic. Productive capacity of lands was determined by the method ofRomanian evaluation agricultural lands (D. Teaci et al., 1980), considering the conditions of relief,climate resources, hydrology, soil characteristics. Land evaluation under natural conditions was basedon participation of ecological characterization indicators, setting the mark of evaluation by limitingfactors.Characterization of climate resources has been achieved using data from the MeteorologicalStation Caracal. Weather data from Weather Station Caracal is between multiannual average isothermsof 11.1 to 12.0 0 C (11.70 C for 2010-2012, representing the period of doctoral research in schools and11.4 0 C for the period 1980-2011). The precipitations regime is characterized by an average annual of525 mm (504.5 mm to 523.0 mm for the period 2010-2012 and 1980-2011). For the category of arable,note the result of evaluation by calculating the arithmetic mean of evaluation notes for 8 crops namely:grain, barley, corn, sunflower, potato, sugarbeet, soybean, peas-beans. Characterizing the main soilprofiles for the three fields the mark of evaluation for arable is 61, and crops: grain, corn and sunflowermark of evaluation is 65. Production achievable under natural conditions of climate (kg of product to thepoint of evaluation by D. Teaci et al., 1980) is 3900 kg / ha for grain, 5200 kg / ha for corn and 1950 kg/ha for sunflower. Technological sheets were prepared for crops of grain, corn and sunflower, accordingto the technology applied to every case. Following the application of advanced technology, productionswere higher than anticipated.
