Between the morphological, chemical, physical and hydrophysical characteristics of soils which directly influence the composition and life medium of phytocoenosis and which have a determinant role in establishment of measures for sustainable utilization of soils, used in present by the pedological school from our country, we mention: gleysation, stagnogleysation, reaction, humus reserve and the content of main nutrients (N, P, K), texture, porosity, low edaphic volume etc. Agricultural technological systems have major effects on the main characteristics of soil, as was observed within the researches made in the stationary experiments on long term or different physical models. The approached problematic is referring to 869.665 ha, 702.398 ha being represented by agricultural lands.
