A dataset of Gansu soil species based on the Second National Soil Survey

Abstract

Based on the results of the Second National soil Survey, Gansu Soil Species was established to accumulate systematic, standardized and quantitative data of soil classification as a solid foundation for the development of soil science in Gansu province.This dataset is based on the processing and integration of Gansu Soil Species published by Gansu Science and Technology Press in 1992. The original data and information of 285 soil species in the book (e.g. attribution and distribution, main characters, production performance summary, physical and chemical properties of profiles) are extracted and collected in a standardized, structured and digital way, integrated with 8 specialized subject data tables indexed by species ID and species name, and conducive to the development of online query, including soil species classification, distribution and characteristics of main soil types, basic information and distribution of soil species, sampling sites and occurrence layers of typical profiles, statistical physicochemical properties of typical profiles and soil species profiles, etc. This dataset can be widely used in regional land quality assessment, environmental effect research, soil carbon storage research, etc., providing significant scientific support for the promotion of new agricultural technology and rational utilization of soil resources.
