During agroecological transition, farmers test and adjust new cropping practices that can enhance the ecosystem services of their agrosystems. Supporting farmers to change their practices requires a description and understanding of the step-by-step design of innovations, and the learning processes that unfold with the farmers’ actions. Our research focuses on the re-introduction of horse-drawn tillage in viticulture, during on-farm experimentation involving the collaboration of a service provider. Our objective is to show how our research approach, based on the use of videos, allows us to access, characterize, and share the knowledge embodied and mobilized in situ by the service providers, considered here as farmers. To do so, we mobilized the methods of the course-of-action research program. First, we filmed the hilling operations performed by two service providers on thirteen plots. We then conducted self-confrontation interviews to highlight their implicit and invisible activity. Next, we conducted an allo-confrontation interview with a third service provider to validate/invalidate and complete the knowledge mobilized during the hilling activity. Finally, through a comparative analysis, we developed a first provisional qualitative modeling of the hilling activity. We thus show that the equine traction service providers used not only visual cues but also sound, tactile, and relational cues with the horse, to adjust their practices; and we illustrate the advantages of using videos to decompose the individual activity of service providers, to then share and compare this activity with those of peers, and, finally, to recompose the hilling activity in a qualitative model by identifying key dimensions structuring the activity. The use of digital technology makes it possible to construct data on farmers’ learning processes as they change their practice to support agroecological innovations. The material produced and the insights gained can contribute to the building of digital resource banks that are valuable tools for training.

在农业生态转型期间，农民测试和调整可以增强其农业系统生态系统服务的新种植方式。支持农民改变他们的做法需要描述和理解创新的逐步设计，以及随着农民行动而展开的学习过程。我们的研究重点是在涉及服务提供商合作的农场实验期间，在葡萄栽培中重新引入马拉耕作。我们的目标是展示我们基于视频使用的研究方法如何使我们能够访问、表征和分享服务提供商（这里被视为农民）在现场体现和动员的知识。为此，我们动员了行动过程研究计划的方法。第一的，我们拍摄了两个服务提供商在 13 个地块上进行的爬山作业。然后，我们进行了自我对抗访谈，以突出他们隐含和无形的活动。接下来，我们与第三家服务提供商进行了一次 allo-confrontation 访谈，以验证/无效并完成在爬山活动中调动的知识。最后，通过比较分析，我们开发了第一个登山活动的临时定性模型。因此，我们表明，马牵引服务提供商不仅使用视觉提示，还使用声音、触觉和与马的关系提示来调整他们的做法；我们说明了使用视频分解服务提供商的个人活动，然后与同行分享和比较该活动的优势，最后，通过确定构建活动的关键维度，在定性模型中重构登山活动。数字技术的使用使得构建农民学习过程的数据成为可能，因为他们改变了他们的做法以支持农业生态创新。产生的材料和获得的见解有助于建立数字资源库，这些资源库是宝贵的培训工具。
