- Abstract:
- Soil erosion control by means of soil conservation practices has gained importance in vineyard management of recent years. However, evaluation of soil erosion risk at regional scale remains difficult as little information is available on the heterogeneity of vineyard management and its effects on soil loss. The viticulture fields of Eastern Austria are handled at a very small scale, thus land use management may vary greatly across neighbouring fields. Management practices range from keeping fallow soils to the perpetuation of a constant vegetated cover throughout the year. However, amount and intensity of soil cultivation do have influence on soil erosion susceptibility. In a field research conducted over the time span of one year, different land use management systems were identified and dynamics of soil cover development were recorded for 6 different sites located in the regions around the villages of Göttlesbrunn and Purbach east of Vienna. By combining measured and modelled data individual soil cover parameters for every researched vineyard were predicted and transformed into soil loss using the well known C-Factor of the Revised Universal Soil Loss Equation (RUSLE). The effects of regional land use management forms and cultivation practices were compared and evaluated with regard to their respective erosion reduction potential. An overall C-Factor of 0.06 was calculated for the entire study site while individual field plot C-Factors range from 0.01 to 0.38. Moreover, results indicated that a combination of reduced surface disturbance and increased vegetation cover fairly reduces the erodibility of soils.
