Approached issues refer to a 869665 ha area of which 700477 ha of agricultural terrains.Vegetation growing conditions (with hard impact on terrain production), together with environmentalfactors soil characteristics, represent a majour component with multiple manifestations due not only to itsown proprieties but also to its depositing capacities for other environement factors influence. We brieflypresent physical and geographical characteristics of this zone , their edaphic cover structure andspecific features of each zone, respectively their favourability regarding main crops in natural oranthropically modified conditions. This paper presents main aspects refering to the zonal and microzonalcharacter of agriculture, definitory and decisive determinant factors of terrain productive capacity,present and potential ecologic favourability, dynamic character of yield as an expression of a certaindevelopment stage and of weather phenomena in the territory. As agroecosystems element, the soil mayfavour productivity through a range of defined specific properties, such as: quantity, quality, equilibriumof nutritive elements, thermic and hydric regime, mineralogic composition, etc. These factors cognitionpresent a considerable practical and theoretical importance. The soil types characterised and definedand identified within main fisical and geographical units of Timis County , constituted basic elementsin zones , microzones defining and the main areas agroeconomic. Areas of agroeconomic groupsadministrative and cadastral territories farms based on element similar on the sensitive: the conditions ofrelief, climate, soils, introduction of irrigation technique and equipment (inland communications, food,etc.), traditional agricultural activity, and also the profile of the territories considered in so far as itmeets the criteria on the achievement of a sustainable development perspective. The research of eco-pedological conditions, ordering and processingof dates was done in accordance with DevelopmentMethodology of Soil Studies (Vol I, II, III), developed by ICPA Bucharest in 1987 and the RomanianSystem of Soil Taxonomy (SRTS-2012).
