Processing of conventional soil survey data using geostatistical methods

Original language description

The aim of this study is to find a suitable treatment of conventional soil survey data for geostatistical exploitation. Different aims and methods of a conventional soil survey and the geostatistics can cause some problems. The spatial variablity of claycontent and pH for an area of 543 km2 was described by variograms. First the original untreated data were used. Then the original data were treated to ovrcome the problems that arise from different aims of conventional soil survey and geostatistical approaches. Variograms calculated from the original data, both for clay content and pH, showed a gig portion of nugget variability caused by a few extreme values. Simple exclusion of data representing some specific soil units (local extremes, non-zonal soils) did not bring almost any improvement . Exclusion of outlying values from the first three lag classes that were the most influenced due to a relatively big portion of these extreeme values provided much better rsults. The nuggetdecrease
