<p>This data comes from the book "Soil of the Kyrgyzstan Soviet Socialist Republic" compiled by the Institute of Soil Science of the Academy of Sciences of the Kyrgyz Soviet Socialist Republic in 1974 The book consists of one volume. It was written under the guidance of the Soviet reclamation movement in 1954 and on the basis of soil field surveys organized by the Ministry of Agriculture or local government departments in various states. Experts and scholars from the Soil Research Institute of the Kyrgyzstan Academy of Sciences collected, sorted and comprehensively studied historical data and field field survey data. The purpose of soil survey is to understand the situation of agricultural land and unreclaimed land during the reclamation period and select suitable reclaimed land for planting. The results formed served Kyrgyzstan's agricultural production and agricultural planning at that time. The data includes soil physical and chemical property indicators, bacterial distribution, spore species composition, fungal particles, etc. In 2017, the Central Asian Ecology and Environment Research Center of the Chinese Academy of Sciences obtained a scanned copy of this book from the Library of the Kazakhstan Academy of Sciences through an international cooperation project. The research team reviewed the resolution, storage format, and whether there is compression, etc. of the PDF scanned files in accordance with domestic archives industry standards. The scanning quality was reviewed, and then the data tables with "soil profile" information were selected from the scanned files, and the pages where these data tables were located were OCR recognized to generate xls format files. The identification results were also inspected for quality; Russian professionals were organized to translate and organize the preface, chapter summaries and soil data table headers in the book, and the Chinese header information and content data were combined to form a spreadsheet version of the "1974 Kyrgyzstan Soil Data Set." Soil professionals corrected the header information with professional terms, and the data included 134 profile sampling points. The numerical values, decimal places, and units of measurement have not been modified and have been checked by multiple people many times. </p>
