Mapping the topsoil pH and humus quality of forest soils in the North Bohemian Jizerské hory Mts. region with ordinary, universal, and regression kriging: cross-validation comparison
Black Triangle digital soil mapping geostatistics map accuracy
2015/3/9
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated ac...
Mapping soils using the fuzzy approach and regression-kriging case study from the Považsky Inovec Mountains, Slovakia
fuzzy k-means regression-kriging digital landscape data grid interpretation spatial distribution soil classification
2015/1/30
The paper introduces a method of digital mapping of spatial distribution of soil typological units. It implements fuzzy k-means to classify the soil profile data (study area from the Považsky Ino...

Artificial neural networks bulk density cone index regression models water content
2009/1/8
Penetration resistance (PR) is an important property of soils, and can be expressed as cone index (CI). Because of high variability, there are no accurate and representative PR data in most cases. Va...
