Assesment of Degradation Processes and Limitative Factors Concerning the Arenosols from Dăbuleni-Romania
Abstract: Soil degradation can be described as a process by which one or more of the potential ecological functions of the soil are harmed and also like a process that lowers the current and/or future capacity of the soil to produce goods and services. The arenosols from Dăbuleni Plain, located in the SW of the Romanian Plain, have a large extension due the aeolian sand deposits which covers the Danubian loess terraces. The main degradation processes affecting the arenosols are the removing and deposition of soil material by wind forces. This type of degradation causes loss of topsoil and severe sand accumulation, which reflects in terrain deformation. The loss of topsoil induces a decrease in depth of the A horizon due to the removal of soil material by the wind because of their sandy texture and insufficient protection offered by vegetation. We should also mention that the forest shelter belts are being destroyed. An irregular removal and depositions of soil material by wind action causes deflation hollows, hummocks and dunes which lead to “terrain deformation” with severe consequences concerning land quality.
