Since ancient times, agriculture has been a vital area of human activity. It is the only source of food, but also a major supplier of raw materials, both for industry and market. Human evolution leads to the creation of optimal conditions for the development of the agricultural sector and it becomes a fundamental activity that will increase the local economy. The man begins to get his own food, while modernizing agriculture. (ARDELEAN V., ZĂVOIANU I., 1979, BORCEAN I, 1996) Agricultural development is the result of the changes stimulated by demographic pressure aimed at increasing agricultural production to ensure the basic food needs for a much larger population than the one currently existing. Dorobanți is located in the Western Romanian Plain, namely in its central part. The structure of the plain was formed over the crystalline foundation of the Pannonia Depression. The perimeter presented, although located in a plain, has various morphological differences, which has led to the fragmentation of the territory into three geomorphological subunits. These subunits are represented by the Comlăuș Plain, the Macea Plain and the Turnul Iratoş Plain. (COSTE I, 1986) The Comlăuș Plain is a small area located east from and at about 1.5 km from the territory of Curtici and south from the Curtici-Sântana county road. The Macea Plain: from under the loessoid materials with low thicknesses come out the sands that cover a wide strip about 2.5 km wide oriented towards NW – SE. The Turnul Iratoş Plain: over the sands existing at the end of the Quaternary, the beginning of the Halocene, there were loessoid deposits of relatively small thicknesses of 2.0 m similar to those of Banat at Biled Bulgaruş Lovrin. From a geological point of view, nature is of particular importance, showing the physical and chemical properties of the parental materials of the soils. In the Comlăuș Plain to date appear loessoid deposits of fine medium texture, reshaped, rich in carbonates. In the Macea-Curtici Plain, Zimand, the soils formed on sands. The texture of soils formed in some interdunes is medium (medium clay), or medium and fine sandy clay. (IANOŞ G, 199, IOAN OANCEA, 2005) On dune ridges, coarse fractions show higher values. To the west of the area occupied by the sands, namely the Macea-Curtici Plain, Zimand-Cicir, in the studied perimeter, over the sands, at the end of the Quaternary, the beginning of the Halocene, the loessoid materials were deposited. Their thickness is small and does not exceed 1.5 to 3.0 m< much of them have been reshaped. The territory under investigation is characterized by a moderate continental temperate climate with shorter and milder winters with a certain circulation of air masses of various types, circulation marked either by centres of action of dynamic origin (Azores and subtropical anticyclone), or seasonal thermal action centres (Siberian anticyclone, Asian or Mediterranean depression).
