COMPARATIVE STUDY OF SOIL INFILTRATION CAPACITY AT SELECTED SITES Summary

The study deals with definition and cross-comparison of soil infiltration capacity at two selected sites located in cadastral territories of Nosislav and Žabþice, Czech Republic. In order to assess the soil infiltration capacity in the ar-eas of interest Niva and Kovál over the course of the 2010 growing season, four trips were made with three measurements taking place during each trip. A method of double-ring infiltration measurement was applied, based on the use of two con-centric cylinders in field conditions and the subsequent data processing via geo-graphical-empirical method according to Kostiakov. The soil infiltration capacity was assessed with regard to physical properties determined by an analysis of intact soil samples using Kopecky cylinders. The results indicate a reduced infiltration capacity due to soil compaction and also significant differences between the two sites, primarily caused by differences in soil type and, hence, different physical characteristics.
