Description	In this study kriging and inverse distance weighting methods were used to compare their performance. Ordinary kriging with the default linear variogram and with the modelled variogram were implemented. Inverse distance weighting method with powers p=1, 2, and 4 was used. Two data sets of high sampling density on the field of an area of 54 ha with a higher and a lower variability were used in the comparison. The results show that the choice of the interpolation method for characterizing the spatial heterogeneity of the soil properties does affect the resulting map. Kriging with the modelled variogram produce smoothed maps, while kriging with the default linear variogram show all levels of the measured values. Inverse distance weighting method tends to generate maps with a pattern of round areas, which size is strongly dependent on the used value of the power p.
