Temi di ricerca

 

1 Current research activities


Scientific activity refers mainly to soil science (marginally jointed to agricultural, archaeological and hydrological projects) in Alpine areas and Prealps, in a framework of international co-operation.

 

 

The main subject of my studies concerns soils and the humus forms as connection for the fluxes of energy and matter in soils. The project where I worked on regard manly forest ecosystems to investigate the relation between soils and the adjacent geosystems, in particular of the role of humus with relation to the different types of epipedon and soils and with relation to vegetal covers.

The investigation pointed out a wide evolutionary variability of forest humus in the studied sites, permitting to identify a probable association trend between different growing-phases of forest and specific humus forms.

 

 

The characteristics observed in field were correlated with classical chemical and physical soil analyses. In order to discriminate the dominant soil forming process, the soils were described and classified in each site according to the World Reference Base (FAO, ISRIC et ISSS 2006), Soil Taxonomy (2006) and Référentiel Pédologique (AFES-INRA,1998).

 

 

I’m the team leader of a working-research team of young science researcher that is studying the evidences of the global change in the Alpine Ecosystem.

 

I have a great passion on studied subjects, meeting my obligations and giving evidence of my capacity to reach the prefixed objectives. I like to work in a multi-national context orientated to collaborate with different disciplines. I’m working in a International Humus Research Group (

 

 

 

http://humusresearchgroup.grenoble.cemagref.fr).

 

 

During the International Stage 2006 : 8th May - 18th July 2006 with the OCDE (Organisation for Economic Co-operation and development, Co-operative Research Programme: Biological Resource Management for Sustainable Agricultural Systems) I investigated, with the support of Prof. Nobuhide Fujitake, Professor of Soil Science (Kobe University, Dept. of Biological & Environmental Science, Faculty of Agriculture), how a forest ecosystem could be a model for agricultural sustainability in a biological and sustainable farming (close to Masanobu Fukuoka’s and Bill Mollison’s approach). This research is be done in Honsu and Kyushu islands (Japan).

During the course of the studies I had work experiences at the University of Milan-Bicocca, at the CNR (National Research Centre) IRPI, Institute of Turin for hydrogeologycs protection of Padanian Basis and at the Centre of Alpine Ecology (located in Monte Bondone, Trento).

 

 

I had many experience on field work, in education institutions and my present contract it’s a temporary science teacher contract in a Secondary School. I have shown significant work qualities of continuity and determination, as already I ascertained by the regularity of my studies.

Since July 2001, I have been working at the Centre of Alpine Ecology with several temporary contracts. The research activities of the last 5 years were done for the projects “DINAMUS” and “INHUMUSnat2000 - Humus forms–indicators of functionality for Nature 2000 sites” have been carried out in Italy, in the Centre of Alpine Ecology through field surveys, elaborations of data and interaction with European research groups. In the laboratory of the Centre, analysis and further elaborations of data have been executed as well.


Silvia Chersich has been graduated in Environmental Sciences in 1997 at the University of Milan with a multidisciplinary thesis on survey, analysis and classification of Mexican soils.

 

 

The following year she started to collaborate with the University of Milan-Bicocca, the CNR (National Research Centre) and IRPI (Institute of Turin for hydrogeologics protection of Padanian Basin). The main subject of her studies concerns soils: investigation of forest and natural ecosystems, soil processes, soil survey, soil analysis and soil classification. Projects have been done in Alpine areas and Prealps, in a framework of international co-operation.

 

 

Since 2001 to 2006 she has been working at the Centre of Alpine Ecology as head of soil research. She started to coordinate soil and humus survey field campaign and provide support to international project with national and international partners. The main subjects of study have been: role of humus with relation to the different types of epipedon and soils in relation to vegetal covers, the soil and humus survey, analysis and classification. All these subjects have been discussed in the PhD on Soil Science (2000-2003). From 2004 she’s working in a European Humus Research Group (http://humusresearchgroup.grenoble.cemagref.fr). She’s working also in a research team of science researchers that is studying the evidences of the global change in the Alpine Ecosystem were she is the team leader.

 

 

The research activities of the last 5 years were done for EU project that have been carried out in Italy through field surveys, elaborations of data and interaction with European research groups. Analysis and further elaborations of soil data have been executed due to classify the soils (to the WRB/FAO, Soil Taxonomy and Référentiel Pédologique). She has begun to write publications from 1997 till now in even more relevant Journals (Montecchio D et al., 2006. Journal of Thermal Analysis and Calorimetry, vol. 83(2006)2, pp.393-399. IF:1,587 -2009 ). All her research activity is documented by publications.

She has many experiences on education and from 2008 she was working as temporary professor on Soil Science at the Pavia University Department of Earth Sciences. She’s in contact with foreigner researchers on many projects and she likes to collaborate in multidisciplinary and multiethnic environment in an international network as she believes it’s a big opportunity to growth for both. Her attitude, towards soil professor activity is to taking responsibility and to find the best way to publicising, informing, communicating the research findings.

During her multi-disciplinary research activities she travelled extensively (Mexico, Russia, Czech Republic, Japan, and French Polynesia). All the scientific activity refers mainly to Soil Science and Environmental Science, to agricultural- archaeological-and hydrological- science. From 2000 she starts to investigate the soil of organic farms. She recognized the relevance to deeper the knowledge on forest ecosystem narrow to the farm and the relation with agricultural sustainability and soil fertility in biological and sustainable farming (close to Masanobu Fukuoka’s and Bill Mollison’s approach). She recognized the importance of this study for the development of the EU agriculture and she is convinced that scientific study can give an effort on it.

 

 

During 2006 she deeper her knowledge on this topic through the Co-operative OCDE Project on Biological Resource Management for Sustainable Agricultural Systems where she has worked in the Japanese laboratory of Kobe University. The aim of the project was the definition and selection of soil indicators for biodiversity assessment in agro-ecosystems.

At the Mycological Congress, Sagliano Micca (BI-Italy), 9/10/2005 she was invited to show the first results of the pedologic survey in a agro ecosystem with a low farming system. The topic has given the opportunity to collaborate with other researcher as Prof. V. Bianciotto for studying the interaction between soil and mycorrhizal (“Arbuscular mycorrhizal fungal biodiversity in low impact agro system” 53° Annual Genetic Italian Society Congress, Turin, 16-19/9/2009. Poster Session).

 

2- SUMMARY of the Degree Thesis in Environmental Sciences of Silvia Livilla Chersich

Title:"Studio pedologico-ambientale della piana del lago di Cuitzeo (Michoacán, Mexico) Centrale)"

Proposer: Prof. Franco Previtali

Co-proposers: Dr. ssa Isabella Assi, Dr. Roberto Comolli, Dr. Giuseppe Crosa


 

The object of the work relates to the analysis of environmental conditions of an area characterized by high ecological, agricultural and productive interest. Phenomenons of natural and anthropogenic degradation are taken into consideration. The study interests an area of 32.800 ha lying in Central Mexico (Michoacán region), between  the latitude 19°57'-19°46' N and the longitude 100°49'-101°13'O, and consists in two different approaches: a soil survey and an ecological study.

On February 1996 a soil survey with an observation density of one section of soil each 1261 ha was carried out. The most significant sections were examined being: apparent and dispersed texture, pH in water, total carbonates, cation exchange, cation exchange capacity, total acidity, electrical conductivity. Further analyses were made on soil resulting particularly saline so as to evaluate the cause of such chemical condition and the upgrading of salinity.

Having at one's disposal meteorologic data, local climatic and pedoclimatic considerations could be made. Soils have been classified according to USA (Soil Taxonomy, 1994) and French taxonomy (Référentiel Pédologique, 1995).  In the ecological study, chemical and phytoplantonical analyses were done in respect of the quality of the Río Grande de Morelia waters. Soils were found: belonging to Mollisols, Vertisols, Alfisols, Entisols. The French classification shows SODISOLS-REDUCTISOLS that evidences how hydromorphic processes are connected with the salinization of soil due to water logging connected with a superficial water table. The chemical characteristics of the water table seem to be influenced by the chemical composition of superficial waters which have a high ecological pollution linked with a high human pressure (sewage sludge). In this particular case from the study of Rio Grande de Morelia's water, it results that the water, coming from the fields, are less rich of nutrients and soluble salts if compared to those  from higher zones. Irrigated soils contribute to depurate the water because of their high capacity to hold the cations especially sodium. The salinity and sodicity of irrigation water remains however a source of heavy problem for its use in agriculture. 


3- Summary of the subject studied on PhD Degree Thesis on Pedology (XV cicle) at University of Palermo (Italy), ACEP Department, Agronomy, Coltivazioni Erbacee e Pedologia, Viale delle Scienze, 90128 Palermo. Coordinator: Prof. Carmelo Dazzi Tutor: Prof. Franco Previtali 

“Studio degli humus forestali e del ruolo che essi investono nella conservazione del suolo degli ecosistemi forestali”

“Study of forestal humus and of their roules in the evolution of the soils of forestal ecosystem”


The PhD concerns the study of forestal ecosystem, in particular the investigation is on the role humus relates with different types of epipedon and existing relations with vegetal covers.

Humus plays crucial role on transformation of the residual vegetation upon the surface of the soil; it represents an important source of information about the nutrient cycles.

A target of PhD is the knowledge of the dynamics of humus formation under leaves forest and under Picea excelsa forest.

I started to study humus form in a Prealps area (300-500 m.a.s.l) under moor vegetation with porforitic rocks. In the vegetation it was found: chestnut-trees (Castanea sativa), oaks (Quercus petreaea, Q. robur), cherry-trees (Prunus avium), birches (Betula pendula), grey alders (Carpinus betulus).

The last year the humus form was studied in the Picea Alpine forest in Alpine sites of the “DINAMUS” (DINAmic of huMUS) Project of “Centro d’Ecologia Alpina” del Monte Bondone di Trento. This is in Italy the biggest Centre for humus form study. I worked in a research team with different subject of study: animal of the soils and humus, micromorphology, fungi, vegetation (sinusia), climate,.. The scientific research is related with projects belonging to principal thematic area of: Forestal ecology.

In alpine environment we studied and classified soil profiles and humic profiles in order to understand the role and the mutual influences of humus and soil in forest ecosystems.

We studied the role of humification process in the genetic development process involving soils and vegetations.

Study sites are located at an altitude of 1770 m a.s.l The parent soil material is predominantly acid. The soil temperature regime is cryic, while the moisture regime is udic. Forest cover consists of alpine spruce forests.

The forest ecosystem was defined using integrated synusial phytosociology (Gillet, Gallandat, 1996; Gillet, 2000). This method allowed us to identify at first 4 relevant steps of the forestry dynamics in the sites were we opened the pedo-humic profiles. The characteristics observed in field were correlated with classical chemical and physical soil analyses. In order to discriminate the dominant soil forming process, the soils were described and classified in each site according to the World Reference Base (FAO, ISRIC & ISSS, 1998). Humus was described and classified using the morphological-genetic approach (Jabiol et al., 1995).

By the correlation of vegetation, humus, and soils data, we emphasized the role of compared study of soil structure with humus forms as a good morphological index of the pedological processes. This allowed us to associate a definite humus form with a pedological process at a particular step of the forest evolution.

We concluded that the morphological-functional approach can provide information useful for formulating hypotheses about the role of humus forms in the soil evolution in the forest ecosystems.

The two sites analysed were:

1-       Madonna di Campiglio (Pinzolo) Tione forestal distrect, Pinzolo forestal station (X= 640815.994 Y= 5122410.761, Arc explorer) with the follow characteristics: South Exposition, 1770 m a.s.l. Altitude, acid with moraine quaternary cover, presence of idric erosion, Vegetation: 94,8%  of Picea excelsa; from Odasso (2001), the spruce wood is a “pecceta altimontana silicicola tipica” with dominance of acid species as Avenella flexuosa, Calamagrostis villosa, Calamagrostis arundinacea, Deschampsia caespitosa, Athyrium distentifolium, Anthirium flix-foemina, Dryopteris dilatata, Homogyne alpina, Hieracium sylvaticum, Luzula albida, Luzula nivea, Rubus idaeus, Vaccinium sp.,

2-       Dieci- Fazzon- Pellizano Val di Sole, Malè forestal distrect, Ossana forestal station (X= 1637958.795 Y= 5127925.759, Arc explorer) with the follow characteristics: North Exposition,  1740 m a.s.l. Altitude, acid with moraine quaternary cover; no erosion, Vegetation: 95,7 % of Picea excelsa with4,3% of Larix decidua. Of ; from Odasso (2001), the spruce wood is a “pecceta altimontana dei substrati silicatici” with dominance of acid species as Avenella flexuosa, Calamagrostis arundinacea, Calamagrostis villosa, Deschampsia caespitosa, Athyrium distentifolium, Anthirium flix-foemina, Dryopteris dilatata, Homogyne alpina, Hieracium sylvaticum, Luzula albida, Luzula nivea, Rubus idaeus, Vaccinium sp.

The soil temperature regime of the sites is Cryic (con 0<Tm<8°C) and the moisture regime is udic (the soil moisture control section is not dry in any part for as long as 90 cumulative days per year (humid climate or humid- temperate).

The soil Processes examined in the field were:
- Brunification

There is the freedom of Fe from the minerals of bedrock and the formation of aggregate of Fe-clay and humus. Characteristic it’s the presence of a cambic horizon (with an alteration in situ, reddish colour, good developed of soil structure).

- Podzolization

Leaching of Fe, Al and organic matter from A to B horizon that made a spodic horizon (reddish, with spodic materials composed of organic matter and Al) under an eluvial horizon (albic, ochric). It is typical of cool, humid, and acidic environments.

Pedological samplings are taken in the field. Soil and humus classification are done after pedological analyses (morphological and chemical).

The soils and humus forms were characterized with Chemical analysis: pH  H2O, KCl (measured potentiometrically; 1:2 soil to liquid mixture), Organic Carbon (O.C.-LOI-%) direct estimation of organic matter by loss on ignition, Organic Carbon (O.C. W&B%) by wet digestion (Walkley and Black procedure), Organic Carbon (O.C.%) with Elemental analyser and muffle, Organic matter O.M % = C. org. % x (1,724), Total nitrogen (Nt) with Elemental analyser, Real Texture (KUNZE, 1965, 5 fractions), Total acidity,  Potential acidity and exchangeable cations CECCONI S. , POLESELLO A. ( 1956), Cation Exchange capacity, Base saturation percentage.

The analytic method used was the:"Metodi ufficiali di analisi chimica del suolo" (Ministero delle risorse agricole, alimentari e forestali, 1994; “Met. Uff. n.VII.3 “Suppl. Ord. G.U. n. 248 del 21.10.1999).

In the site elaboration of pedoclimatic data (humidity and temperature of the soil) has done.

4-Work experience:  Project “DINAMUS – Humus forms and forest dynamics”: an interdisciplinary approach to an ecological study


Project DINAMUS is an example of an interdisciplinary study of the climate-soil-plant system. The aim of this work is to combine the study of humus forms dynamics with a vegetational study for the main development stages of a spruce forest: open canopy, regeneration, intermediate, and mature wood. In order to achieve this goal, the integration of various disciplines related to forest ecology is necessary. In this project, humus forms dynamics was studied at a detailed scale, so that this alpine spruce forest system could be defined using synusiae. Field work consisted of the following surveys: vegetational (using the integrated phytosociological synusial method), humus form (using transects), pedological, climatic, soil fauna, mycorrhiza and mycological. In the laboratory, the samples of OH and A horizons were observed stereoscopically, with the aim of identifying the principal organic and mineral components of each layer.

In addition, traditional chemical and physical analysis on soil samples were made, and qualitative and quantitative aspects of organic and humic substance present in the A horizon were determined, with particular attention to the study of hormone-like activity.

In the Region Trentino Alto-Adige, 59 soils and humus profiles were studied and classified in order to understand the variability of soils and humus forms in alpine forest ecosystems. In particular, the evolution of humus forms was investigated in relation to the development of vegetation cover, with the aim of determining whether a humus form can be representative of a specific forest phase. For the study of humus profiles, transects were traced so as to cut across all 4 principal dynamic phases of forest evolution: open canopy, regeneration, intermediate and mature. Two sub-sites (of about 1000 m2) were selected at an altitude of 1700 m. a.s.l., on parent soil material of morenic sediments on acid substrate and with a vegetation cover of alpine spruce forest: the first, having a north exposition, is located within the Municipality of Pellizzano in Val di Sole, near Mount Nambino; the second, with a south exposition, is located near Madonna di Campiglio, in Val Rendena, near Mount Ritorto. The soil temperature regime is frigid, while the moisture regime is udic. Our investigation pointed out a wide evolutionary variability of forest humus in the studied sites, permitting to identify a probable association trend between different growing-phases of forest and specific soils and humus forms.


INHUMUSnat2000 Project

The soil study, completed with the data and the elaborations made by the others different Project Groups, aims to characterize the possible indicators of the conditions of the  environment (used/anthropized or not). The reconstruction of the pedogenetic process that control the genesis and evolution of the different pedotypes supplies with information  useful to the interpretation of the ecosystem dynamics.

The survey planning carried out on 2005 and 2006 years. On 2005 we acquired general informations concerning the studied environment (morphological and vegetation characters of the studied sites). In particular we collected samples of different rocks and we described and sampled 12 soil profiles in the sites (the permanent test sites excluded) to evaluate the representativeness of the pedons and their variability in the other test sites and to observe the soil profiles under spruce in the Tovel Valley. In addition, we collected photos in the permanent sites. During the 2006 we planned a support contribution to the work of the other groups through the soil survey and the acquisition of detailed pedological data in the 4 study permanent areas. All the collected chemical  and survey soil data will undergo a statistic analysis and a summarizing interpretation. The soil survey of 2006 was focused on the analyses of a reference soil profile (with  morphological and chemical analyses and classification) for each permanent site. More in detail, we identified the synusia number 6 (leaf layer) because it is present in all the 4 sites.

Chersich S. et Sartori G., 2007. Viote Soil Map.Report Centro di Ecologia Alpina n. 39. Trento.

The results of the study carried out by the Centro di Ecologia Alpina on the soils of the Piana delle Viote and adjacent slopes, in the Monte Bondone Group (Trento), are presented. The area (roughly 500 ha) shows a great variability in the parent materials, landforms and vegetation covers. Hard limestones, marly limestones, eolian deposits, glacial deposits with a calcareous lithology, and with mixed calcareous and siliceous lithology, the latter with a prevalence of one of the two lithologies. The detailed scale adopted (1:5,000) has permitted a precise assessment of the relationships between the soils and the environment, and of the effects of past human activity. Due to the cold and wet climate, soils with relatively high carbon contents in the topsoil, not calcareous and acid, are prevalent. Most of the of the soils, with the exception of the shallow soils of the alpine meadows (ST: Lithic Cryrendolls) and/or of very steep slopes (Typic e Lithic Haprendolls, Inceptic Haprendolls), show a clay accumulation in the B horizon (Typic o Inceptic Hapludalfs). A podzolisation process can be detected on the glacial deposits very rich in siliceous elements and relatively rich in coarse fractions (Typic Haplorthods).

Particular attention was paid to the humus forms of both forests and meadows, and to their relationships with the chemical and physical characters of the topsoils, with the vegetation covers and to changes induced by human activity. A wide range of humus forms have been observed, resulting either from the activity of anecic worms (“biomacrostructured” mull), or of endogeic worms (“biomesostructured” mull), or enchytreids (moder). Micromorphological investigations of the humus forms have enabled a verifi cation and deeper comprehension of the fi eld observations and of the chemical data.

Progetti di ricerca

Outline of planned research

Researches on forest ecosystem, on soil and humus and development.

I am very concerned with forest humus, soils, sustainable agriculture, vegetation, hydrology and geomorphological studies.

 

I’m working on the following research:

 

  • Evidences on the soils of Global Change in the Alpine Ecosystem

The Alpine ecosystem is very sensitive to climatic changes, therefore it is an optimal marker to record them. The aim of this work is to describe the effects of global change on the soils. We observe the effect of the global change on the Alpine land, from the top of the Alpine horizon (2400-2600 m. a.s.l.) to the lower Alpine altitude (timberline).

The Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR) argues that the frequency of intense precipitation events will likely increase, especially in winter. General Circulation Models (IPCC, 2001) forecast a higher frequency of extreme rainfall events, a lower amount of rainfall days, and longer intervening dry periods. Regional Circulation Models applied to European Alps show that Alpine climate in the latter part of 21st century will be characterized by warmer and more humid conditions in winter, and much warmer and drier conditions in summer.

The effect of climate changes on landscape dynamics can be investigated on geomorphic features deposited or produced during the LGM (Late Glacial Maximum) or Holocene period, when a dramatic temperature increase was recorded within a relatively short period of time. This situation has some parallels with nowadays in lands with similar climate and contextual challenges as North America, Australia (Snowy Mountains) and New Zealand. In fact, the European Alps have lost about half their glacier mass during the past 150 years. Generally, impacts of changing in temperature and precipitations regimes on Alpine ecosystem result in glaciers retreat, decrease in snow cover extent, earlier snowmelt, permafrost melting (with consequences in destabilisation of mountain walls), changes in river runoff systems, reduction in annual duration of lakes and rivers, upward migration of Alpine plants, changes in phenology, extensive species losses (in some areas up to 60% under high emissions scenarios by 2080), especially concerning endemism, due to invasive species (IPCC, 2001, 2007).

 

 

  • Humus forms : ecological indicators and pedological processes

I’m working with International Humus Research Group (http://humusresearchgroup.grenoble.cemagref.fr) and the Topsoil Network (topsoil@ispa.uni-vechta.de) for the description of the relation between humus forms and pedological process due to use these knowledge for revision and expansion of FAO Draft (www.plant-soil.com).

Humus can’t be regard as a single element as for the soil. It’s been proved (Chersich et al., 2005) as the relations between soil and humus it’s not only binded on the superficial horizons of the soil (A horizons) but also on the deepest one (B). Besides, where the pedogenetic process of the soil is the result of a unsteady factors equilibrium, the humus form, often, is the dete rmining factor to suggest  if the pedogenetic process that we observe is in equilibrium with the environment or is developing to a new pedogenetic process. In a natural condition, the soil, as ecosistemic component, is liable to the pedogenetic process  and directly to the humologic process.In the climax stage the humic process appears only apparently to haven’t an influence on the pedogenetic process and it is considered that existed a good soil inertia degree in reply to the superficial outside modifications.

According to Jenny equation (1941) the soil that we observe in a certain morphological position is the result of the parent material transformation occurred in a circumscribed time, under climate and biota action. The weight of each single factor depends on the ecological environment where the soil is developed. From m the ecological poin of view we have to regard the pedogenesis as a reply of following environment change that has benn perceived as soil self-evolution stages.

 

  • Chemical analysis for the soil and humus interpretation

Using the datas of DINAMUS and INHUMUSnat2000 projects (5 years datas) I would like also to correlate the japanese podzols soils with the italian one. I’m working on relation between soil and humus chemical datas, soil and humus morphological description, vegetation,pedofauna, morphology, parent material and climate of the site.. I’m looking for a description of the geosystem with the analisis of the dinamic fluxes of energy and matter.

  

  • Field work

The scientific research is related with projects belonging to principal thematic area of: Forestal ecology. We studied the role of humification process in the genetic development process involving soils and vegetations.

Due to deepen the humus broadleaf knowledge, it’s starting the measuring of the thickness of the humus horizons (OL- leaf horizon and OH humificated horizon) during the year in a broadleaf forest. In the same time we are collecting the quality and quantity humus data. The site is located in a Prealps area (300-350 m.a.s.l) on porforitic rocks, under chestnut-trees (Castanea sativa), oaks (Quercus petreaea, Q. robur), grey alders (Carpinus betulus) vegetation.

In alpine environment we studied and classified soil profiles and humic profiles in order to understand the role and the mutual influences of humus and soil in forest ecosystems. Humus was described and classified using the morphological-genetic approach (Jabiol et al., 1995).
