Research goal is to accumulate scientific data on development of components of agricultural land productivity, necessary to support of an methodology of their quality evaluation through a complex firm approach to physical and geographical conditions from Banat Plain. Research on ecometrical function of the main physical and chemical characteristics of soil have been taken by many scientists, in the country and abroad, since the beginning of last century and the German classification system was designed mainly based on soil texture in the so-called phase of its evolution (D. Teaci, 1980). As part of the soil, clay plays a role in the relations established between certain physical and chemical properties of soil and between them and the activities of organisms that inhabit it.The physical and chemical properties of soil samples (texture, pH, content of humus and NPK etc.), were analyzed in USAMVB-OSPA Timisoara Research Laboratory, after national norms and standards approved by the Standards Association from Romania (ASRO). Knowledge of these features of the soil are of special theoretical and practical importance. Theoretical, it provides to specialist the possibility to interpret the phenomena that occur in soil and to predict soil evolution in particular and the environment in general, in terms of present and future health, and practical because warns the physician as what measures should be taken to bring the soil in optimal conditions for growth and development of plants cultivated or wild. Importance, originality and timeliness of work is the need to protect the edaphic layer and environmental protection by: The accumulation of scientific data necessary to support technologies of consevative tillages and sustainable management of soil and water resources, Implementation of conservative tillages and sustainable management of physical, geographical and edaphic conditions from Banat Plain.

biovariety, cooperation, sustenability, monitoring.
