This paper aims to obtain a fund of pedological and agrochemical information on the soil cover in Șagu commune, Arad County in terms of its properties: morphological, physical-mechanical, hydrophysical and chemical, in order to establish their quality in terms of productivity and data regarding the nature and intensity of the limiting factors and of the possible degradation phenomena, which should substantiate technically-scientifically the most adequate technological measures specific to each distinct piece of land from an ecological aspect. The soil, as a means of production in agriculture and horticulture, has certain peculiarities, which distinguish it from other means of production. Thus, the soil is a natural means of production, which is formed and evolves on the land surface, over time and under the influence of environmental conditions. Also, unlike other means of production that wear out by use, the soil, if used rationally, not only does not reduce its fertility but, on the contrary, can increase it. In the case studies are presented the analysis and graphic interpretation of the analytical data obtained following the sampling of soil samples from Șagu commune, Arad County and their physico-chemical analysis. The soil is connected to the environment through a continuous flow of matter and energy. In its long evolution, under the action of natural and agricultural factors, the soil tends to a steady state, characterized by equalizing tendencies of imports and exports of energy and substances. The type of soil found within Sagu locality, Arad county is preluvosol, with two studied subtypes, vertical-stagnant and stagnant. The problems of raising the fertility of the soil must be seen both in terms of current requirements to increase agricultural production, improve the quality of primary production (and not only) and increase yields in agriculture, and their harmonious combination with the main parameters physico-chemical properties of the soil, with which they are in close interdependence.
