Wednesday, 22. January 2020, the small exhibition “Grund und Boden – was highly appreciated in the Amberg State Archive. The soil estimate in the Oberpfalz – from analog to digital” opens. The exhibition is a cooperation project of the Amberg State Archives with the Office for Digitization, Broadband and Survey Amberg and the Weiden Finance Office. What is a field or a meadow worth? What's the ground? How do climate and water conditions shape? Answers to these questions arise from the soil estimate. The soil estimate is an inventory of agricultural soils according to the nature of their use and their natural viability. It is used to tax agricultural assets, but it is also important as a basis for determining value in land transport and rural development, land protection and land information systems. The exhibition with about 60 exhibits traces the history of soil estimation from its beginnings in the 1930s to the present and presents its organization and execution yesterday and today. Estimation cards and estimates books, which have only recently been submitted to the Amberg State Archive, documents, practical instructions, photos, technical equipment and soil samples, are shown. A fair distribution of the loads according to ownership and economic power has always been a reason for the tax on land and land. In addition, the exhibition therefore illustrates the prehistory: possessions and tax books from the Middle Ages and early modern times as well
