Biodiversity-friendly farming practices may create a win-win scenario for biodiversity and crop production by supporting ecosystem services to agriculture. On-farm wildflower plantings and conserving semi-natural habitat surrounding farms are two such practices that focus on the integration of non-crop components into production systems at the local and landscape scale, respectively. Here, we examine the impact of these practices on the regulating services of biological control and pollination, as well as the provisioning service of crop yield in four crops replicated across 22 farms in two US states. Wildflower plantings had no effect on pollination while their influence on pest control was both dependent on the landscape context and inconsistent across crops. In contrast, farms surrounded by higher amounts of semi-natural habitat had consistently higher marketable yields for all four crops. Our findings suggest a need to account for non-production values of wildflower plantings as they provide fewer direct production benefits than surrounding semi-natural habitats.

通过支持农业生态系统服务，生物多样性友好型耕作方式可以为生物多样性和作物生产创造双赢局面。在农场种植野花和保护农场周围的半自然栖息地是两种这样的做法，它们分别侧重于将非作物成分整合到当地和景观规模的生产系统中。在这里，我们研究了这些做法对生物控制和授粉调节服务的影响，以及在美国两个州的 22 个农场复制的四种作物的作物产量供应服务。野花种植对授粉没有影响，而它们对害虫控制的影响既取决于景观背景，又因作物而异。相比之下，被较多半自然栖息地所包围的农场，所有四种作物的适销对路产量始终较高。我们的研究结果表明需要考虑野花种植的非生产价值，因为它们提供的直接生产效益少于周围的半自然栖息地。
