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 …
Changes in soil organic matter and soil humic substances following the afforestation of former agricultural lands in the boreal-nemoral ecotone (Latv…
2019
Abstract Abandonment of agricultural land is a widespread process in Northern Europe, which is associated with changes in content and distribution of organic matter in soil, including C stocks. There is insufficient information on changes in soil organic matter properties during afforestation of these lands. The aim of the study was to determine and describe the influence of afforestation on organic carbon (CORG) content and properties of soil organic matter (SOM) in mineral topsoil in the boreo-nemoral ecotone in Latvia. We studied soils in 4 model territories that represented abandoned farmlands and territories where mixed or coniferous forests were established at different times on forme…
An anthropic soil transformation fingerprinted by REY patterns
2009
Abstract This Focus article deals intentionally with modern soil disturbance in situ . This is of interest to archaeologists as after disturbances, both short- and long-term, pedogenesis (re-)starts obliterating previous signs. Soil modifications induced by human activity may be linked to pedogenetic evidence for disturbance with archaeological evidence for the cultural activities. We contrasted two 750-m 3 soil pedons, an Anthrosol and a Kastanozem, from which the Anthrosol is derived, using 77 descriptors of soil properties which have been utilized in archaeological studies (pedo-morphological, routine laboratory, biochemical, metals and rare earth elements plus yttrium, REY) with the aim…
Anthropogenic soils as the marker
2017
This article aims to support the Anthropogenic soils, the ones markedly affected by human activities, as the most meaningful marker for the onset of the Anthropocene. Although diachronous and not uniformly distributed throughout the world, these soils in fact show more prominently and potentially longer in time than other proposed markers for the impact of humans on the Earth surface.
Spatio-Temporal Effects of Land Use Change on the Anthropogenic Soils Diffusion: A Case Study in a Mediterranean Vineyard Area
2008
Anthropogenic soils created ex novo by land-use change in large scale farming are, from a pedogenetic point of view, catastrophic events that bring the soils to time zero and change the natural pattern of the soilscape, remarkably, in some cases. The quantitative aspects of pedodiversity of a soilscape in South-East Sicily, where some types of soils, in recent decades, have suffered a consistent reduction due to the transformations by large scale farming, are considered. The evolution of pedodiversity over a 53-year period (1955 to 2008) is examined using a dedicated statistical method and a space–time model based on Markov analysis and cellular automata in order to predict the evolution of…
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 …
Parastās egles Picea abies kā edafikatora ietekme uz smilšainas augsnes virskārtas īpašību izmaiņām bijušajās lauksaimniecībā izmantojamās zemēs
2016
Bakalaura darbā ir pētīts Latvijā arvien aktuālāks jautājums par augsnes īpašību izmaiņām saistībā ar bijušo lauksaimniecības zemju apmežošanās procesu, jo līdz šim ir veikti relatīvi maz pētījumu. Bakalaura darba mērķis ir noskaidrot 15 gadus vecas parastās egles Picea abies (L.) H.Karst ietekmi uz smilšainās augsnes virskārtas īpašību izmaiņām bijušajās lauksaimniecībā izmantojamās zemēs. Pētījums tika veikts Vidzemes augstienē, Taurenes apkārtnē, „Jaņu” viensētas tuvumā, kur augsnes cilmiezi veido smiltis. Pētījuma rezultāti parāda, ka parastā egle Picea abies (L.) H. Karst ietekmē smilšainās augsnes īpašības bijušajā lauksaimniecības izmantojamā zemē, ir konstatētas izmainās tilpummasas…
Development of protofragipanic horizon after severe degradation processes of greenhouses soil
2014
Plant growing in greenhouses and plastic tunnels has some advantages: obtaining early production, plant protection against hail, hoarfrost, late spring and early autumn frosts. The main criteria considered for setting greenhouses are the existence of heating and water sources. Due to the compulsory location imposed by the above conditions, many greenhouses were placed on soils having low capability. After application of ameliorative measures some satisfactory results could be obtained on a relatively short period. Our studies on some soils in greenhouses and plastic tunnels in Romania have shown that after 15-20 years of the intensive exploitation an impermeable soil horizon with brittle bl…
Anthropogenic soils: general aspects and features
2015
In recent decades man's role in soil formation has become a matter of great concern among soil scientists. Man is now considered a soil-forming factor and anthrosolization is recognised as a soil-forming process that consists of a collection of geomorphic and pedological processes resulting from human activities. These human activities include deep working, intensive fertilization, the addition of extraneous materials, irrigation with sediment-rich waters and wet cultivation. In this paper we review the influence of man as a soil forming factor stressing also some peculiar aspects linked to their classification.
