Abstract

The increase in the soil organic carbon (SOC) content has well-acknowledged positive effects on the soil chemical, biological and physical fertility. Recent global warming concerns have recommended maintaining and restoring soil carbon as a measure to mitigate rising atmospheric carbon dioxide (CO2) concentration (Follett, 2001; Lal, 2008). Organic fertilization is one of the most diffused practices that increase the SOC content (Smith, 2004), and composting park or municipal solid wastes has become an important way to recover organic matter from wastes (Gigliotti et al., 1996; Centemero, 2007). The objective of this paper was to assess the potential of compost fertilizer addition to influence the maize crop yield and the soil carbon sequestration, compared to green manuring and minimum tillage. Preliminary results are here discussed. Preliminary results suggest that compost supplied at low-medium rates may exert a negative effect on maize growth, especially in poorly-aerated soils, probably owing to the immobilization of N. An increase in the SOM content could not be detected after the first applications to the soil.
