THE SOILS FAVORABILITY FOR THE MAIN AGRICULTURAL CROPS IN THE ARAD PLAIN PUBLISHED

ANDREI ILIUȚĂ, DORIN ŢĂRĂU
Increasing production and agricultural land fertility are directly determined by the detailed knowledge of soil processes, of evolution, and of the measure in which soils are supplied with nutrients. 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. 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 Arad 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). Previous research contain numerous analytical data over a period of over 40 years, an interval in which there were numerous methodology, mapping, abd assessment of agricultural lands. As both soil features are dynamic, in close relation with solification conditions, it is necessary to re-assess physical and chemical features, nutrient supply, and soil favourability for the main crops in the Arad Plain.
