Abstrakt:
Soil water properties are one of the most important soil features which determine water distribution and its availability for plants. Therefore, the aim of the study was to describe selected soil air-water properties and assess the size of spatial autocorrelation for soil properties. The soil samples were collected from a two-hectare field located in the mesoregion called Sępopol Lowland, in north-eastern Poland. The area is covered with Eutric Gleyic Cambisols formed from glaciolimnic sediments. Soil water retention properties as well as bulk and specific densities were analysed. The following soil pores and soil water capacities were calculated: macropores, mesopores, micropores, potential useful water retention (AWC - available water capacity), and among AWC, readily available water capacity (RAWC), and small pores available water capacity (SAWC). Geostatistical analyses as a function of the semivariogram and correlogram were carried out using Isatis Geovariance. The shares of the macro-, meso- and micropores in total porosity were similar. The lack of autocorrelation in the case of mesopores and micropores was noted. However, small autocorrelation was found in the case of SAWC, which was confirmed by a small nugget effect.
