As a national Agri-environmental Programme in Austria, ÖPUL subsidises mulching/no-till and cover crops to mitigate soil erosion. In this study, the participation rates and effectiveness of these ÖPUL-measures are analysed. In addition, the impact of different farming systems (conventional farming vs organic farming) on the soil erosion risk in Austria are compared. A national analysis is carried out, while local data is implemented at the scale of agricultural fields. Therefore, we use the well-established Revised Universal Soil Loss Equation (RUSLE). The analysis demonstrates that 1) soil erosion is strongly related to regional-specific management practices, and ÖPUL-measures in their current form are not consistently applied in areas where erosion mitigation is desired, 2) the ÖPUL-measures mulching/no-till and cover crops are not used to their full potential due to a lack of participation, while fields with implemented ÖPUL-measures indicate a significantly lower chance of soil erosion > 11 t ha⁻¹ yr⁻¹ than others and 3) the lower soil erosion in organic farming is due to a lower proportion of erosion-prone crops in the crop rotation compared to conventional farming. Soil erosion > 11 t ha⁻¹ yr⁻¹ is approx. 1.5 times more likely on conventional fields compared to organic fields, suggesting that both farming types require further erosion mitigation strategies. Actual implementation rates cannot reach the potentially high effectiveness of ÖPUL-measures against erosion. The authors suggest that participation could be raised if options for additional measures are offered by the ÖPUL programme, such as grassed waterways or micro dams in potato farming.

作为奥地利的一项国家农业环境计划，ÖPUL 补贴覆盖/免耕和覆盖作物以减轻土壤侵蚀。在本研究中，分析了这些 ÖPUL 措施的参与率和有效性。此外，还比较了不同农业系统（传统农业与有机农业）对奥地利土壤侵蚀风险的影响。进行全国分析，同时在农业领域实施本地数据。因此，我们使用行之有效的修正通用土壤流失方程 (RUSLE)。分析表明 1) 土壤侵蚀与特定区域的管理实践密切相关，目前形式的 ÖPUL 措施并未始终如一地应用于需要减缓侵蚀的地区，⁻¹ yr ⁻¹比其他农业低，并且 3) 与传统农业相比，有机农业中较低的土壤侵蚀是由于作物轮作中易侵蚀作物的比例较低。土壤侵蚀> 11 t ha ⁻¹ yr ⁻¹是大约。与有机田地相比，传统田地的可能性高 1.5 倍，这表明这两种耕作类型都需要进一步的侵蚀缓解策略。实际实施率无法达到 ÖPUL 措施防止侵蚀的潜在高效性。作者建议，如果 ÖPUL 计划提供额外措施的选择，例如马铃薯种植中的草地水道或微型水坝，则可以提高参与度。
