Patterns of rock fragment cover generated by tillage erosion

Auteur(s) et Affiliation(s)



Description :
Intensively cultivated areas in the upper part of the Guadalentin catchment (southeast Spain) show a systematic spatial pattern of surface rock fragment cover. The objective of this paper is to quantify and to explain this spatial rock fragment cover pattern. Therefore, a map of an intensively cultivated area of 5 km2 was digitised, and for each pixel total topographic curvature was calculated. The results clearly indicate that tillage erosion is the main process responsible for the observed rock fragment cover pattern in the study area.
