土壤信息对于农业研究和发展至关重要。在像赞比亚这样的发展中国家，土壤信息的可用性受到新的土壤调查费用的限制。遗留的土壤信息可能有助于填补这一空白。这项研究评估了赞比亚南部和东部省份遗留土壤信息的可用性。我们还研究了调查比例尺、图例、边界密度和地图纹理。我们研究了C.G. Trapnell从1932年到1942年在该地区，评估土壤，植被，景观和农业系统提供的信息。向在卢萨卡举行的各利益攸关方讲习班介绍了这一遗产的概况，并征求了他们对遗产效用的意见。已知在这两个省进行的大规模调查中，60%以上无法追踪，在追踪的调查中，有些地图页无法获得。大多数调查报告都是硬拷贝，有些报告的状况很差，只有7份报告的扫描本可在国际标准资料和解释信息中心网站上查阅。地图比例尺和纹理与一般预期不完全一致，地图纹理与评估地图中较小的出版比例尺一致。利益攸关方认为，尽管存在一些局限性，但遗留信息仍是一种宝贵的资源，这表明，在现代土壤信息中可以有效地复制其中的一些特征。为土壤图单位提供的整体评估可能比单一属性图更容易获得。获得和了解土壤信息被视为一个限制因素。目前迫切需要保存赞比亚和其他国家仍然存在的遗留土壤调查报告和地图。这就需要对材料进行实物保存，使其可供使用，并与现任和退休的土壤测量员密切研究，以保存他们对材料制作过程的记忆，以及他们对如何解释材料的理解。保存工作应包括扫描硬拷贝报告，并将其存储在国家、区域和全球土壤调查数据中心，并提供链接以方便访问。利益攸关方对传统土壤调查形式的热情表明，重新开展系统的土壤调查是有价值的。
Soil information is essential for agricultural research and development. In developing countries like Zambia, the availability of soil information is limited by the cost of new soil surveys. Legacy soil information could be useful to fill this gap. This study evaluated the availability of legacy soil information in Southern and Eastern Provinces of Zambia. We also examined the survey scales, legends, boundary density and map texture. We examined a number of exemplar transects undertaken by C.G. Trapnell from 1932 to 1942 in the region, evaluating the information provided on soil, vegetation, landscape and farming systems. An overview of this legacy was presented to a workshop of varied stakeholders in Lusaka, and their opinions on its utility were elicited. More than 60% of large-scale surveys known to have been conducted in the two provinces could not be traced and among those traced some map-sheets were not available. Most of the survey reports exist as hard copies and some are in poor condition, while only 7 are available online on the ISRIC website as scanned copies. The map scale and texture were not entirely consistent with general expectations, with map texture consistent with a smaller publication scale in assessed map-sheets. Stakeholders regarded the legacy information as a valuable resource, despite some limitations, suggesting that some of its features could usefully be reproduced in modern soil information. The holistic assessment provided for soil map units may be more accessible than single-property maps. Accessibility and understanding of soil information is seen as a limitation. There is an urgent need to preserve the legacy soil survey reports and maps that are still available in Zambia, and in other countries. This entails physical preservation of material, making it available, and studying it closely with current and retired soil surveyors to preserve their recollection of how it was produced and their understanding of how it should be interpreted. The preservation should include scanning of hardcopy reports and storage in national, regional, and global soil survey data hubs with links provided for easy access. Stakeholder enthusiasm for the format of legacy soil surveys suggests that renewed systematic soils surveys would be valuable.
