However, the successful growth of ginseng requires particular environmental conditions, with soil quality being one of the most important factors restricting the growth of this plant. Therefore, understanding the optimal soil conditions for ginseng is essential to the healthy development of the ginseng industry. Currently, broad•leaved mixed forest (BM) , conifer and broad•leaved mixed forest (CB) , and Quercus mongolica forest (QM) are widely distributed forest•ginseng agroforestry stand types. In this study, we selected nine samples from three stand types in eastern Liaoning Province, China, that had similar stand characteristics but different ginseng cultivation years. Twenty•five soil quality factors were measured, including physical, chemical, and biological indicators. We then established the minimum data set (MDS) of forest•ginseng agroforestry soil assessment using analysis of
