The enhancement of production and agricultural land suitability depends directly on a comprehensive understanding of soil processes, evolution, and the extent to which soils receive nutrients. The fundamental purpose of land evaluation is to assess its characteristics and qualities in order to determine its optimal use. The classification of farmland is established through land assessment, following an evaluation of its natural state. The concept of "land" encompasses all environmental elements (such as soil, topography, climate, hydrology, etc.) that exert a significant impact on its utilization. Land evaluation under natural conditions involves the incorporation of ecological characteristics and indicators to establish stringent evaluation criteria. The analysis of soil samples' physical and chemical properties (including texture, pH, and humus) as well as biochemical aspects was conducted at the OSPA Arad Research Laboratory, adhering to the national norms and standards established by the National Association of Standardization. Examination of ecopedological conditions, data organization, and processing were carried out following the Methodology for the Elaboration of Pedological Studies (volumes I, II, and III), outlined by the ICPA Bucharest in 1987, along with the Romanian System of Soil Taxonomy (SRTS-2012+). Previous studies have presented extensive analytical data spanning over four decades, during which various methodologies, mapping techniques, and assessments of agricultural lands were conducted. Given the dynamic nature of soil characteristics and their close relationship with the conditions of solidification, it is imperative to reevaluate the physical and chemical attributes, nutrient availability, and soil suitability for land utilization in the Arad Plain.
