CURRENT ASPECTS OF SOIL EROSION WORK ON AGRICULTURAL LAND DURING THE PERIOD 1990 - 2016 IN IASI COUNTY PUBLISHEDSimina-Mirela RĂILEANU None email@example.com
Most agricultural lands in Iasi County are located on slopes with different degrees of inclination. Areas affected by erosion all over the territory are significant and from 1990 until now the situation has worsened. For all slope agricultural land it is necessary to perform land improvement works on soil erosion control. Combating erosion, improving eroded land and bringing it to a high degree of fertility requires arrangements, measures and works to be applied differently for each situation. As early as the 1960s - 1970s, measures were taken to prevent and combat this degradation process by making anti-erosion arrangements on appreciable surfaces, these consist of: agrotechnical works to combat soil erosion on agricultural land with arable land and landscaping works with vineyards and orchards, improvement of pastures. The objectives are aimed at analyzing the exploitation behavior of soil erosion control works on the slopes of the studied area for a period of 16 years and proposals on the prospects of combating soil erosion. At the same time, also the destruction of important soil protection and soil conserving works on the slopes (brooks, terraces, debris, banquets and coastal canals). Considering that at the county, surfaces with lands requiring landscaping are also significant in relation to the pace at which such arrangements have been made so far, in the perspective of this, special financial efforts are needed for their extension In order to achieve the proposed objective, the data obtained from the study of the topographical maps (sc 1: 50,000 and 1: 100,000) and the soils (sc 1: 200,000), the information on the evolution of agricultural use and the anti-erosion works, as well as the findings fieldwork on slope processes and soil erosion control work by the research team involved in the topic. Rehabilitation of anti-erosion works and the execution of new ones are imperative in the county.
