Abstract Increased use of cover crops to promote soil health in high-intensity row-crop agroecosystems has resulted in more frequent reports of damage to soybean (Glycine max) commodity crops by voles (Microtus). Meadow (M. pennsylvanicus) and prairie voles (M. ochrogaster) may use overhead cover and forage provided by cover crops and browse soybean seedlings after emergence in spring. Because cover cropping is a recently adopted conservation practice, few methods have been evaluated for their relative effectiveness in preventing vole damage in cover-cropped fields. We used boosted regression tree models to assess how farming practices, physical and landscape attributes of cover-cropped soybean fields, and seasonal weather conditions were associated with severity of damage by voles across Indiana, USA. We found non-linear, asymptotic relationships between risk of vole damage and number of days of snow cover the preceding winter, percent of well-drained soils, and number of years of cover-crop use in a field. Damage risk was greatest at intermediate levels of grassland vole habitat within 50 m, and risk was lower when conservation tillage was applied. Our results can be used by producers to identify fields and years where vole damage is most likely to occur and identifies farming practices most likely to mitigate risk in those fields.

与覆盖作物田中田鼠 (Microtus) 损害相关的田地属性和耕作方法

摘要 在高强度的中耕作物农业生态系统中,越来越多地使用覆盖作物来促进土壤健康,导致更多关于田鼠(Microtus)对大豆(Glycine max)商品作物造成损害的报道。Meadow (M. pennsylvanicus) 和草原田鼠 (M. ochrogaster) 可使用覆盖作物提供的架空覆盖物和草料,在春季出苗后采食大豆幼苗。由于覆盖作物是最近采用的保护措施,很少有方法对其在防止覆盖作物田间田鼠损害方面的相对有效性进行评估。我们使用增强回归树模型来评估耕作方式、覆盖作物大豆田的物理和景观属性以及季节性天气条件如何与美国印第安纳州田鼠的破坏严重程度相关联。我们发现非线性,田鼠受害风险与前一个冬天积雪天数、排水良好的土壤百分比和田间覆盖作物使用年数之间的渐近关系。50 m 范围内草原田鼠栖息地的中间层受害风险最大,采用保护性耕作时风险较低。生产者可以使用我们的结果来确定最有可能发生田鼠危害的田地和年份,并确定最有可能降低这些田地风险的耕作方法。
