EVOLUTION OF THE COMPONENTS OF AGROECOSYSTEMS PRODUCTIVITY FROM BANAT PLAIN, MURES-BEGA INTERFLUVE, IN 2011-2012 AGRICULTURAL YEAR

The research are for grounding of sustainable agriculture system, responding of local demands of establishing scientific database and to develop technology actions necessary to support integrated management of agroecosystems. They were made in the stationary experience, in the field of OSPA Timisoara, organized in two locations: Sanandrei and Jimbolia, representative for Banat agricultural area. At Jimbolia, the experiences are placed a typically chernozem, dominant in Jimbolia - Bulgarus plain and representative for a large area of Banat low plain, as part of Mures Plain, at south of the current course of the Mures. At Sanandrei, the experiences are placed on a an mollic reddish preluvosol, dominant in Plain Vinga and representative of a large surface of Banato-Crisana plain. The goal of research its found theyr origins in current scientific and practical preoccupations to identify and put in place an integrated management of agroecosystems, agronomic effective, with limited energy and financial efforts, ecological and conservativ for the soil and environment. To achieve the objectives, the research were oriented toward the observations and measurements made in the experimental field and in the validation of these observations by laboratory analysis. The research of the ecopedologic conditions was made according to "The methodology of elaborating of pedological studies", vol. I, II and III elaborated by the ICPA Bucharest in 1987, completed with specific elements from the Romanian System of Taxonomy of Soils (SRSTS-2003/2012). Research consists in the accumulation of scientific data on the development of components of agricultural land productivity, on the supply of atmospheric, cosmic, relief and soil, necessary for substantiation of current cultural technologies of performance use of these resources through a complex firm approach of physical-geographical and climatico-edaphic conditions from Banat Plain soils (Mures-Bega interfluve). They were investigated in relation to environmental factors, natural or anthropical, which makes the existence, together forming units ecologically homogeneous area (TEO's) with specific suitability or favorability and different technological requirements.
