摘要
The results are discussed of studies of the spatial variability of water retention, bulk density, natural moisture content, and cation-exchange capacity using tge theory of regionalized variables, taking into account the influence of the distance between sampling points on the variance of the distributions of the investigated soil characteristics. Semivariograms of water retention curves revealed a weak spherical spatial structure with high values of nugget variance, whose influence ranged from 21 to 63 m.
