Proposal for a new diagnostic horizon for WRB Anthrosols
2009
Abstract To investigate man's role in the creation and evolution of soils in areas of large scale farming, and to investigate the main morpho-descriptive aspects of the related soils, a survey was carried out in south eastern Sicily, Italy, where, as common to other regions of the Mediterranean basin, there are wide areas with anthropogenic soils due to large scale farming activity. The complex genesis pattern of these anthropogenic soils, which shows a double sequence of man-made horizons, sideways oriented to the soil surface, does not allow their classification as Technosols, because their composition is not dominated or strongly influenced by artefacts or human-made materials as is the …
Realizzazione della carta digitale dei suoli della Sicilia utilizzando il rilevamento GIS-oriented e un modello CLORPT
2011
Produrre una carta digitale dei suoli della Sicilia (1:250.000) di tipo quantitativo, che combinasse l’approccio tradizionale deterministico con un modello CLORPT, e introducendo nel fattore rilievo i processi geomorfologici è stato lo scopo della ricerca. 1.532 profili di suoli (1.363 analizzati) sono stati raccolti da bibliografi a e da rilevamenti precedenti. Una carta fisiografica della Sicilia è stata realizzata per fotointerpretazione e consultando 54 lavori pubblicati di geomorfologia. Altre informazioni geografi che sono state raccolte: una carta geologica della Sicilia, la carta dell’uso del suolo Corine 2000 e la precedente versione della carta dei suoli della Sicilia. La banca da…
Influence of environmental factors on the spatial distribution and diversity of forest soil in Latvia
2012
This study was carried out to determine the spatial relationships between environmental factors (Quaternary deposits, topographical situation, land cover, forest site types, tree species, soil texture) and soil groups, and their prefix qualifiers (according to the international Food and Agricultural Organization soil classification system World Reference Base for Soil Resources [FAO WRB]). The results show that it is possible to establish relationships between the distribution of environmental factors and soil groups by applying the generalized linear models in data statistical analysis, using the R 2.11.1 software for processing data from 113 sampling plots throughout the forest terri…
