<p>This data comes from the book "Soil of Semipalatinsk Oblast", Volume 10 of the series "Soil of the Kazakhstan Soviet Socialist Republic" compiled by the Institute of Soil Science of the Academy of Sciences of the Kazakhstan Soviet Socialist Republic in 1968. The complete set of books consists of 16 volumes. 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 Institute of Soil Research of the Kazakhstan Academy of Sciences collected, sorted and comprehensively studied historical data and 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 the agricultural production and agricultural planning of various regions (prefectures) of Kazakhstan at that time. The writing data of "Soil of Semipalatinsk Region" are based on field soil survey data from 1956 to 1958, as well as publicly published soil survey results and manuscript data on the state in the early 20th century. 1956-1958 The 2000 field soil survey covered 18137 thousand hectares of the state, surveyed approximately 2000 soil profiles and collected a large number of soil samples. The book details the state's physical geography, the history of soil research, soil classification, and the implications of soil research for agricultural production planning. The soil chemical analysis in the book was completed by the laboratory of the Institute of Soil Research, Academy of Sciences of the Republic of Kazakhstan. </p> <p>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. After returning to China, the Central Asian Environment and Ecology Research Center of the Chinese Academy of Sciences organized Russian professionals and soil professional technicians to study the book. The soil profile data table was translated and sorted to form a spreadsheet version of "1968 Soil Data of Semipalatinsk Oblast of Kazakhstan". The data contained 204 profile sampling points. It is inevitable that there will be inappropriate words in the process of translation and collation, but the numerical values, decimal places, and units of measurement are all transcribed according to the situation presented in the scanned document without modification, and have been verified by multiple people many times. </p>
