PHYSICAL-CHEMICAL CHARACTERIZATION OF THE SOILS IN THE AREA OF DOMASNEA MUNICIPALITY CARAS SEVERIN COUNTY.

The first attempts to explain the phenomena of soil formation and evolution were based on one or more pedogenetic factors, which results in the fact that there are a wide range of concepts and formulations in this regard. It is also specified that in the formation of the soil cover, in addition to pedogenetic processes, some geological processes also take place, which interfere with the formation of the soil cover and which are considered pedogeological processes. A thorough analysis of the specific and combined actions of all the factors involved in these processes is necessary in order to explain the genesis of soils and to establish their evolution time, both under natural conditions and under the conditions of their use by humans. This current research is important because it contributes to the knowledge of the physico-chemical characterization of the soil in the Domașnea region, Caraș Severin. This knowledge can contribute to future research on other soiels with similar characteristics. Climate is a particularly active and important factor for soil formation through the complex of meteorological phenomena: precipitation, temperature, wind, air humidity, brightness, and other aspects. The climate influences the process of pedogenesis and soil evolution, both directly and indirectly. Directly, it acts through the amount of precipitation, through the amount of water that evaporates, temperature, wind, etc. The action of the climate on the massive rocks starts right from the first phases of solification, triggering their disaggregation and alteration and their transformation into loose rocks.
