Soil Modelling Studies: Soil Health and Carbon Dynamics (SMS)

Soil Health enhancement, soil carbon dynamics and carbon dioxide removal Miglioramento della salute del suolo, dinamica del carbonio e rimozione del carbonio dall'atmosfera

Conceptual framework of the biochar models

 

Esperimenti di laboratorio e in campo e sviluppo di modelli sulla dinamica del carbonio per la rimozione della CO2 dall’atmosfera e il miglioramento della salute del suolo 

  • studio degli effetti agronomici di lungo termine del biochar (applicato tal quale e in combinazione con fertilizzanti organici e inorganici) 

  • progettazione di esperimenti in campo con biochar (LTEP)

  • inclusione delle dinamiche del biochar nel suolo in modelli dinamici del carbonio nel suolo (es. RothC, MEMS), tenendo conto di feedback e effetti indiretti 

  • inclusione di pratiche agricole conservative nei modelli dinamici del carbonio nel suolo per permettere di stimare la potenzialità di Soil Carbon Sequestration (SCS) 

  • valutazione di modelli già esistenti per il calcolo delle emissioni di greenhouse gases (GHG) dal suolo

 

We aim at investigating the potential for soil carbon sequestration and soil health improvement of different agricultural practices and technological solutions (biochar), by performing laboratory and field experiments and by developing dedicated computer models.
More specifically, our aims are:
    • Study of long-term effects of biochar on soil properties, soil organic matter, and heavy metals in soils.
    • Inclusion of the biochar and its direct and indirect effects on soil organic matter in soil carbon dynamic models.
    • Soil carbon sequestration modelling aimed at calculation of carbon credits.

Presentation

 

The soil is vital for human society; however, climate change and the growth of global population are increasing the pressure on soil worldwide. An healthy Soil, able to provide many ecosystem services, takes a long time to develop from loose material; however, it can degrade very quickly. The soil is also a very complex system, with many biological, chemical and biological processes taking place simultaneously and interacting.

Our group investigates the complex mosaic of soil processes with both experiments and modelling, and aims at assessing methods and practices for the protection of soil health, sequestration of carbon in the soil and management of climate change. Our research is divided into two main areas: mechanistic research, which tries to unfold the tangled processes in the soil through laboratory and field experiments to inform chemical, physical and biological soil models; and systemic research, aimed at understand and model techno-economical and societal issues and present/implement policies for soil protection.

An example of our mechanistic research is the long term field experiment we maintain, in which a mix of compost and biochar is added to the soil every year, while we monitor soil physical, chemical and biological parameters. The knowledge coming from the field research is used to implement models of biochar interacting with soil organic matter, and this models are used then to inform systemic models to help understand how best to produce, distribute and deploy biochar and compost on some specific area.

To make sure our results are verified in various conditions, we created a web of collaboration with other universities and research centres. Finally, we maintain continuous collaboration with agricultural companies willing to decrease their environmental impacts.
