variogram - Opis:
- Presented investigations focused on spatial variability of forest soil pH on an example of luvisols derived from loess with underlier of marlstones. Four study plots were located in different parts of the slope. Marlstones, present deeper than 1 m under loess layer, had most significant influence on spatial variability of topsoil pH. Despite relatively thick separation from the surface, the marlstone layer altered topsoil via upward water movement (influence distributed evenly) or throughout exposed deeper soil layers as an effect of uprooting (specific island−mosaic of pH). Analysis of spatial variability of soil pH emphasize such phenomena as zero distance variability that reached up to 20% of sill, and 2−4 meters of autocorrelation distances. Thus, there is a need of extended soil sampling to cover both: nugget effect and autocorrelation.
