  "abstract": "This study explores the dynamics of optimizing crop nutrition and fertilization strategies in Europe, drawing on qualitative interviews with French experts (n=19) and quantitative data from a pan-European stakeholder survey (n=714, including 152 in France). The primary motivations for farmers to improve crop nutrition are economic and agronomic. Increasing yield potential is the most cited driver (76% Europe, 59% France), followed by reducing fertilizer costs (56% Europe, 47% France), highlighting the importance of input management. Enhancing crop quality (42% Europe, 34% France) and improving soil fertility (42% Europe, 67% France) are also significant. While compliance with agri-environmental legislation is a factor (21% Europe, 26% France), it remains less prioritized than direct economic gains. Notably, French respondents place more emphasis on public policies (43% vs. 25% elsewhere). Major obstacles include the high cost of tools and technologies (70% France, 49% Europe) and low farm income (49% Europe). Farm size also limits investment capacity (40% France). A significant knowledge and training gap is apparent (38% France), compounded by the complexity and insufficient interoperability of digital tools, a point frequently raised by French experts. Traditional practices are hard to change, but are minor factors compared to economic and knowledge barriers. Identified needs largely mirror the obstacles. Farmers prioritize training in soil fertility and crop nutrition (43% France, 47% Europe), along with awareness and practical demonstrations of tools. Access to independent research results and cost-benefit information (35% France) is crucial. Funding for tool investment (34% France) and incentives from industry and public support are also sought. Farmers specifically request independent agricultural advice and reliable, economically viable tools that allow them to adapt fertilizer dosages, reinforcing their desire to remain central to decision-making. The discussion emphasizes the strong interdependence between behavioural factors, knowledge dissemination structures (AKIS), and the collective capacity to produce relevant data. Behavioural barriers like perceived risk and economic uncertainty significantly impact technology adoption. The study highlights the need for localized, reliable data, transparent evaluation of digital tools, and co-development approaches. Enhancing knowledge circulation through robust AKIS, continuous training for farmers and advisors, and addressing interoperability issues are vital. Farmers prefer less automated technologies, and while environmental benefits like water quality improvement are recognized, economic and yield considerations often take precedence. The overall conclusion stresses that a multi-faceted approach, emphasizing outcome-based policies rather than prescriptive means, co-construction with farmers, and strengthening the entire innovation ecosystem, is crucial for a successful and sustainable transition in fertilization practices.",
