During the last 10 years, several attempts to map soil attributes at the scale of mainland France have been realised. We exemplify them by seven major outputs: maps of organic C stocks, trace elements (TE), microbial density and diversity, soil thickness, available water capacity (AWC), extractable P, and changes in soil pH. We first briefly describe the data and the methods used to produce these maps and summarise their main results. We then focus on their impacts on various categories of the public, i.e. the general public and citizens; farmers; private companies; non-governmental organisations; agricultural development organisations, stakeholders, and national agencies; French governmental bodies; and international organisations. We also analyse the demands that came to the French National Soil Information Centre from 2008 to 2018 and the impact that our activities had in various media. Soil organic C had the largest impact in nearly all categories of end-users, which may be linked to the recent ‘4 per 1000’ initiative launched by the French governmentduring the COP21 and to the fact that farmers are interested in increasing the organic matter content of their soil for increasing the fertility. TE obtained high scores, which may be related to citizens' care about health and to the fact that governmental bodies and national agencies have a major interest in site contamination assessments. The soil P content, pH, and AWC exhibited major impacts on the agricultural sector. Maps of the soil P content and pH were used as geomarketing tools by private companies selling fertilisers and soil amendments, whereas the AWC was already incorporated into decision-making aid tools for irrigation management developed by development organisations for farmers. Microbial diversity generated collaborations with a large network of farmers and had a large media impact. Nevertheless, the visibility of soil information to the general public should be increased. This can be done by using new multimedia and interactive tools. Overall, these selected examples of digital soil mapping of soil attributes at the national scale in France clearly indicate that the soil attributes have substantial impact on various categories of end-users, such as farmers, professional organisations, stakeholders, and policymakers at different levels of decision-making, among others. However, the impacts on the general public and citizens are more difficult to quantify, and increasing the soil awareness of the general public should be of high priority.

在过去的十年中，已经进行了几次尝试绘制法国大陆规模的土壤属性的尝试。我们通过七个主要输出来举例说明它们：有机碳储量，微量元素（TE），微生物密度和多样性，土壤厚度，可用水容量（AWC），可提取的P和土壤pH的变化。我们首先简要描述用于生成这些地图的数据和方法，并总结其主要结果。然后，我们集中讨论它们对各种公众（即普通大众和公民）的影响；农民 私人公司; 非政府组织；农业发展组织，利益相关者和国家机构；法国政府机构；和国际组织。我们还分析了2008年至2018年对法国国家土壤信息中心的需求以及我们的活动对各种媒体的影响。土壤有机碳在几乎所有最终用户类别中影响最大，这可能与法国政府在COP21期间发起的“千分之四”倡议以及农民对增加有机物含量的兴趣有关。他们的土壤增加肥力。TE获得了很高的分数，这可能与公民对健康的关心以及政府机构和国家机构对现场污染评估的主要兴趣有关。土壤的磷含量，pH和AWC对农业产生了重大影响。出售肥料和土壤改良剂的私人公司将土壤P含量和pH值的地图用作地理营销工具，而AWC已被纳入农民发展组织开发的灌溉管理决策辅助工具中。微生物多样性与大型农民网络产生了合作关系，并产生了巨大的媒体影响。但是，应该增加土壤信息对公众的可见性。这可以通过使用新的多媒体和交互式工具来完成。总体而言，这些在法国全国范围内对土壤属性进行数字化土壤制图的选定示例清楚地表明，土壤属性对各种最终用户（例如农民，专业组织，利益相关者，以及处于不同决策水平的决策者等等。然而，对公众和公民的影响更难以量化，因此提高公众对土壤的认识应该成为重中之重。
