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

A dataset of Liaoning soil species based on Liaoning Soil Species published by Liaoning University Press in 1991, is one of the results of the Second National Soil Survey in Liaoning Province. We standardize, structurize and digitalize the data of 237 soil species based on their distribution areas, morphologic characteristics, physicochemical properties and productivity. Particularly, the dataset uses seven tables delineating Liaoning soil species, including soil classification, soil basic traits, landscape of typical soil profile, genetic horizon of typical soil, physicochemical properties of typical soil profile, administrative region distribution of soil species, and the names of counties and cities. The dataset can be used for land quality assessment and research on environmental change and soil carbon sequestration. The dataset is important for agricultural structure adjustment and rational use of soil resources. The dataset is also an important reference for the Third National Soil Survey in Liaoning Province.
