Research goal is to accumulate scientific data on development of components of agriculturalland productivity, necessary to support of an methodology of their quality evaluation through a complexfirm approach to physical and geographical conditions from Banat Plain. Research on the main physicaland chemical characteristics of soil have been taken by many scientists, in the country and abroad, sincethe beginning of last century and the German classification system was designed mainly based on soiltexture in the so-called phase of its evolution. The objectives and activities fall within the currentagricultural research and agricultural practice, on international and national level, for the study of theimportance of hydro-physical characteristics of the edaphic coating in substantiation of tillage systems.As part of the soil, clay plays a role in the relations established between certain physical and chemicalproperties of soil and between them and the activities of organisms that inhabit it. The physical andchemical properties of soil samples (texture, pH, content of humus and N,P,K), were analyzed inUSAMVB-OSPA Timisoara Research Laboratory, after national norms and standards approved by theStandards Association from Romania (ASRO). The research of the ecopedologic conditions was madeaccording to “The methodology of elaborating of pedological studies”, vol. I, II and III elaborated by theICPA Bucharest in 1987, completed with specific elements from the Romanian System of Taxonomy ofSoils (SRSTS-2012). Knowledge of these features of the soil have of special theoretical and practicalimportance. Theoretical, it provides to specialist the possibility to interpret the phenomena that occur insoil and to predict soil evolution in particular and the environment in general, in terms of present andfuture health, and practical because warns the physician as what measures should be taken to bring thesoil 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 protectionby: The accumulation of scientific data necessary to support technologies of conservative tillage andsustainable management of soil and water resources, Implementation of conservative tillage andsustainale management of physical, geographical and edaphic conditions from Banat Plain.
