Disambiguating the soils of Mars
2020
Abstract Anticipated human missions to Mars require a methodical understanding of the unconsolidated bulk sediment that mantles its surface, given its role as an accessible resource for water and as a probable substrate for food production. However, classifying martian sediment as soil has been pursued in an ad hoc fashion, despite emerging evidence from in situ missions for current and paleo-pedological processes. Here we find that in situ sediment at Gusev, Meridiani and Gale are consistent with pedogenesis related to comminuted basalts mixing with older phyllosilicates – perhaps of pluvial origin – and sulfates. Furthermore, a notable presence of hydrated amorphous phases indicates signi…

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 …
Anthropogenic processes in the evolution of a soil chronosequence on marly-limestone substrata in an Italian Mediterranean environment
2007
Due to anthropic pressure, many areas of the world are affected by a process of soil “entisolization” that leads to the formation of “anthropogenic soils”. In order to investigate Man's role in soil evolution, a survey was carried out in Southeastern Sicily (Italy), where, for years, there have been wide farming areas with anthropogenic soils. A chronosequence of anthropogenic soils in a vineyard area, cultivated for 22 years, was investigated. The first stage of the chronosequence was made by the original soils which, in the study area, had been undisturbed till the 1980's. These soils, classified as Entic Haploxerolls under the American Soil Taxonomy (ST) or Calcaric Kastanozem according …
Vegetation, soils, and humus forms of Sardinian holm oak forests and approximated cross-harmonization of vegetation types, WRB Soil Groups and humus …
2018
Five plant communities, related to elevation above sea level and geological substrata, are recognized in the holm oak forests of Sardinia (Italy). These forests show a considerable inhomogeneous structure due to present day and past uses. Coppice management prevails, influencing the quantity and quality of organic horizons. Most frequent mineral soils are Cambisols, Leptosols, and Regosols. Regarding the humus forms, Moder and, with less extent, Amphi, are prevailing. Furthermore, the paper presents a synoptic table giving a rough picture of the relationships between vegetation types, WRB Soil Groups and humus forms in selected Mediterranean ecosystems.
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…
Soil interpretation in the context of anthropedogenic transformations and pedotechniques application
2018
Abstract Following a long and vigorous study carried out by the International Committee on Anthropogenic Soils (ICOMANTH), the Soil Taxonomy (ST) classification system recently incorporated a number of changes to include Human-Altered and Human-Transported soils, generally called anthropogenic soils. These changes underwent careful scrutiny as they affect the current classification of existing soil series, and as the proposals and logics are as yet untested against existing data and descriptions. Particular attention was given to the diagnostic characteristics of the anthropogenic soils and to the Subgroups for Human-Altered and Human-Transported soils. In this study, we consider a frequent…
Komunikacja niespójna w teorii i praktyce terapeutycznej
2016
Komunikacja niespójna może wynikać z niezgodności wypowiadanych przez człowieka słów i towarzyszących im zachowań niewerbalnych lub ze sprzeczności między pojawiającymi się w tym samym czasie różnymi przekazami pozasłownymi (np. silny uścisk dłoni kłóci się z czerwienieniem się na twarzy, a zaciśnięte usta pozostają w sprzeczności z gestami rąk znamionującymi szczerość i otwartość). Zjawisko komunikacji niespójnej stało się przedmiotem dociekań wielu wybitnych teoretyków i praktyków psychoterapii. G. Batesona zainspirowało do prac nad zjawiskiem „podwójnego związania"; niespójność w komunikacyjnej teorii podwójnego związania uznano za niezgodność między przekazem słownym i bezsłownym. V. Sa…
