Lack of information still exists on relationships between the land use and various soil management practices on soil aggregate stability. This work focuses on the effect of soil management on soil properties and aggregate stability in the viticulture region where the soils are influenced by management practices such as deep ploughing before vineyard establishment and the long-term cultivation of grapevines and forestry. The obtained results showed marked differences in physical and chemical soil properties between the four study sites. In particular, the soil pH values and the contents of organic carbon and clay-fraction differed significantly. The comparison of the aggregate stability values determined for the various soil management systems indicated differences between the vineyard and forest sites. Soil aggregate stability decreases approximately according to the order where comparable original forest soil and afforested vineyard soil have greater stability than vineyard soil which is more stable than deeply ploughed vineyard soil. From all the soil properties studied, the soil organic matter content appears to be the main determining factor controlling aggregate stability.
