Multi-temporal analysis of erosional plots using aerial images and deep soil probes

Original language description

Evaluating erosion processes and their influence on soil degradation over extensive agricultural landscape is difficult. Because of the need for analysis and mapping of this problem, we elaborated a procedure applicable to a specific, intensively farmed, erosionthreatened chernozem area of CZ or similar regions. The aim of the research was to verify the possibility of digital aerial image analysis, along with a control study of soil sampling. To define and compare the boundaries and extent of erosion and deposition processes, we used images from two different years, showing changes in soil degradation. Orthorectification and unsupervised image classification were followed by interpretation and statistical evaluation. The results, locating erosional, transitional and depositional areas, were verified in laboratory analysis of soil samples for selected soil characteristics. Comparison of aerial images showed changes in the agricultural landscape over 35 years, showing an increase of ca. 60% in erosional areas. Extensive changes also occurred in transitional and depositional areas as material from the subsoil horizon of erosional areas covered some depositional areas. Importantly, our research confirmed the potential of digital aerial image analysis as a method of studying soil erosion over extensive landscape, and the possibility of using it in planning anti-erosion measures.
