Variabilità della salinità dei suoli lungo un versante collinare della Sicilia centrale

È possibile stimare le variazioni dei crediti di carbonio forniti dai suoli agricoli e forestali italiani

2011

L’Italia ha aderito al Protocollo di Kyoto, ma ha deciso di eleggere solo la gestione forestale nell’ambito delle attività addizionali previste per contabilizzare i crediti di carbonio. Lo scopo principale di questo lavoro è stato quello di dimostrare che è possibile stimare le variazioni del contenuto di carbonio organico dei suoli in Italia durante gli ultimi 3 decenni (dal 1979 al 2008) e contabilizzare i crediti di carbonio originati dalle attività di gestione sia agricola che forestale.

USING WRB TO MAP THE SOIL SYSTEMS OF ITALY

2012

Aim of this work was to test the 2010 version of the WRB soil classification for compilating a map of the soil systems of Italy at 1:500,000 scale. The source of data was the national geodatabase storing information on 1,414 Soil Typological Units (STUs). Though, basically, we followed WRB criteria to prioritize soil qualifiers, however, it was necessary to work out an original methodology in the map legend representation to reproduce the high variability inside each delineation meanwhile avoiding any loss of information. Each map unit may represent a combination of three codominant STUs at the most. Dominant STUs were assessed summing up the occurrence of STUs in the Land Components (LCs) …

Biotechnology of the Recultivation of Technogenically Disturbed Landscapes in the South and East of Kazakhstan (биотехнология рекультивации техногенн…

2018

Reclamation of technogenically disturbed lands requires several procedures and assignments. In the South of Kazakhstan during the field development of phosphate deposits, pastoral type lands were disturbed. Reclamation works were done in two stages - technical and biological. The technical stage included the dump planning, loamy ground delivery for bottom lining, layer-bylayer covering and stabilisation. The biological stage included planting of phyto-meliorants, biochar and carbamide insertion under crops. In the city of Ridder, around the mining processing industry, the black humus soil was exposed to aggressive emission of zinc plant. The soil is currently degraded and devoid of vegetati…

Soil genetic erosion: a new concept for a new environmental challenge and a new soil paradigm

2018

The author proposes a new concept of soil erosion to shed new light on soil erosion an ecological environment conservation in order that politicians and administrators could pay great attention to preserve soil resources. A new concept of soil erosion is suggested by proposing ideas, explaining concepts, summarizing and case studies. The economic value should be assigned to the soil ecosystem services and the new concept of soil erosion that could be called “soil genetic erosion” is proposed. Soils are very diverse natural resources that positively affect and promote the economy of the social systems if they are maintained in good health.

SOILS WITH HIGH ORGANIC CARBON STORAGE CAPACITY IN DEPTH

2012

Most studies about soil organic carbon (OC) stock focus on the topsoil storage capacity, however, it has been proved that OC can reach relatively high values also in depth. The aim of this work was a preliminary investigation of the soil types with a high OC content in depth and the relationship with the main pedogenetic factors. The dataset was the 1,414 Italian National Soil Typologies (STU). The selected attributes were: mean value of OC in the superficial functional horizon (L1); weighted average value between 50 and 100 cm (L2) and under 100 cm (L3); WRB classification; main lithology, morphology and land-use. About 92% of typologies had more than 0.58% of OC in L1, about 30% in L2, an…

The influence of industrial emissions from a zinc factory on the properties of Chernozem soil

2018

This article describes the influence of zinc factory emissions on soil cover and vegetation cover of the lands of East Kazakhstan. It is shown how the physical properties of water affect soil moisture. The authors consider how heavy metals destroy the composition of organic acids and how it affects the aggregate state of the soil cover.

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.
