Abstract

The soil surface roughness is one of the most susceptible to variation in time and space characteristic, and depends on many variables like cultivation practices or soil aggregation. Various indices are used for its quantification, in microscale soil roughness is commonly expressed by HSD calculated from DEM of small sample area. The source of DEM can be close range photogramethry or laser scanning. However, for the scale of whole field that approach gives unclear separation, and new approach, based on geomorphons gives better results.
