Potential carbon sequestration of Lombardy soils (Italy)

摘要

Lombardy soils have a high potential capacity to incorporate considerable amount of carbon, if carbon (C) saving land management is adopted. However, the certification of the changes of soil organic carbon (SOC) stock over the time is needed on the basis of transparent and cost effective methodologies. To this purpose, the soil sampling protocol recently proposed by the European Commission's Directorate General Joint Research Centre (JRC) of Ispra has been tested comparing three different land management occurring on the same soil type. Results showed a huge potential SOC sequestration rate ranging from 3,5 and 4,2 tC/ha/year and suggested the soil involvement in land-based C management practice can be actually feasible, even if the influence of soil mass on estimates of carbon storage should be in particular studied in more detail.
