The research made is falling on the line to develop an sustainable agricultural system, responding to local requirements for establishing a scientific database necessary for the development of technology and measures of agroecosystems integrated management. The passing to no-till cultivation system radically changes the content of technological elements, that simplifies the technology by the suppression of soil work, so the impact on the agricultural ecosystem is different from that of conventional technology, first decreases the pressure on agricultural ecosystem and on the other apear new interactions, new disrupt the new balance or imbalances. The research made in the world concerning no-till technology get some information about the implications of this system of agricultural cultivation on the environment, showed that the impact varies from one area to another, depending on climatic and soil conditions encountered, agricultural management. The researches regarding the evolution of the agro-ecosystems quality and productivity from the Vinga High Plain in the no-till crop system tries to highlight the quality and quantity changes emerged in the agricultural ecosystem. There are presented some aspects regarding the physical-geographical characterization necessary for the experimental field localization are presented. Here are briefly introduced the geology and lithology of surface materials, clime conditions, land drainage etc., as defining elements for edaphic resources’ main characteristics. Also, regarding the soil conditions have been determined the defining characteristics for the ecosystems productivity, granulated structure and humus content. In close relation with the first two aspects have been established the water content and the cationic change capacity.. In order to determine the complex relation that take place between different soil characteristics and agro-ecosystems components, the researches were conducted both on field and laboratory.
