ABSTRACT
The term of “soil quality” is utilized until present with different connotations; its meaning became nowadays more comprehensive. The most adequate definition of the “soil quality” is: “the capacity of a specific kind of soil to function, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality and support human health and habitation” (Karlen et al, 1998) One distinguishes a native soil quality, in natural conditions, and a meta-native soil quality, in managed conditions. Also, one can distinguish a stable side and a variable side of the soil quality. It is useful to consider also the term of “soilscape quality”, defined as weighted average of soil qualities of all the soils entering soil cover and their arrangement (expressed by the pedogeographical assemblage). The assessing soil quality can be made indirectly by a set of indicators. The kind and number of the quality indicators depend on the evaluation scale and the objective of the assessment. New researches are necessary to define more accurately the soil quality and to develop its evaluation. Assessing and monitoring soil quality have global implication in environment and society.
