Abstract : In principle , land evaluation is to compare the properties and characteristics of the requirements or demands of land (use) it. Farmland assessment is the basis of their classification as class, after the note of evaluation in natural conditions. In concept assessing the concept of "land" includes all environmental factors (soil, terrain, climate, hydrology, etc.), which have significant influence on use. Because of economic conditions, different land in the same class of evaluation in natural conditions may have different economic outcomes, resulting in the amount of net income and therefore different economic values . Quantitative assessment of land was based on estimated production potential of evaluation by marks, calculated for existing conditions on the ground (current or natural conditions). Note of evaluation (natural conditions) divided the land quality in terms of their quality for agricultural use, and the use of shared framework in terms of production capacity. Agricultural production is adversely affected by restrictions given by some properties of soil, terrain and climate, which show equal intensities, decreases depending on how different productions of land use (arable, pasture, vines), so one and the same land may have restrictions of varying intensity depending on his usage. The land evaluation for natural conditions, ecological characterization participated indicators for determining the coefficients stringent evaluation notes. The physical and chemical properties of soil samples (texture, pH, humus and N, P, K content) and biochemical were analyzed in the OSPA Olt Research laboratory,  according with the national norms and  standards approved by National Association of Standardization. Research of ecopedological conditions, data ordering and processing was done in accordance with the Methodology of Elaboration of Pedological Studies; (vol. I, II, III), developed by the ICPA Bucharest in 1987 and the Romanian System of Soil Taxonomy (SRTS-2003). For details of the work to be as conclusive materials were used in the cadastral records OJCPI Olt. The work was carried out with a good control throughout the stages of work, the final result being given by grades and classes of evaluation. Field units (TEO) which were calculated scores and grades were established quality are concrete forms that appear in certain areas (geographic and historical), territorial units of the ground as concrete forms of manifestation and expression on the surface land, the actual taxonomic rank lowest (ground variations).
