Estimación de volúmenes de suelo perdido por procesos de erosión por piping. Sureste de España.

Abstract

Piping processes have been widely studied in many countries and regions, but especially in arid environments, on marl soils, reach a great development. We studied eight areas affected by piping, located in the Basin of Mula (Murcia), on terraced farmlands and abandoned about 40 years ago. Have been evaluated sediments mobilized by this process and erosion rates. The erosion rate per plot is 287 t/ha/year, undoubtedly, a very high value of soil losses. For this it is necessary soil conservation practices when these fields are abandoned.
