Abstract : Agroforestry is considered a sustainable cultivating methodology in comparison to intensified and one-dimension agriculture, resulting in higher yields, socio-economic benefits and environmental protection as well. The silvoarable systems constitute classification of the agroforestry systems that involve crops and trees in the same spatiotemporal scales. One of the most important benefits related to the productivity of silvoarable systems is the maintenance or improvement of soil quality. In the present study, qualitative characteristics of soils in traditional silvoarable systems in the area of Mouzaki, central Greece, were studied through the determination of basic soil parameters, including the organic matter content, total nitrogen, exchangeable potassium and available phosphorus. All systems under investigation were characterised as boundary hedgerows (livefences). The trees in the hedgerows may include mulberry, wild pear, wild walnut, and other wild tree types typical of the Mouzaki landscape, whereas the understorey crops were both arable and horticultural. Within the research areas, the effect of the trees on the concentration of the selected soil parameters was investigated. Soil samples were collected in all systems at two depths (0-30 and 30-60 cm) and at three distances from the selected trees, corresponding to half, twice, triple or quadruple the tree canopy width. The results of the research provided evidence of C sequestration in all soils under investigation, thus indicating the positive effect of agroforestry systems on the environment.
