ABSTRACT

Abstract The Minimum Data Set (MDS) is an effective way to improve understanding of the assessing soil quality and understanding of the heterogeneity of soil quality and encourage the adaption of proper agriculture practice. However, a suitable evaluation method of the soil quality of Astragalus mongholicus and ecological link between this and the active ingredients, including astragalosides (I, II, and IV) and calycosin, was poorly known in the main cultivation region in China. This study selected 22 soil indicators and 4 active ingredients factors and used principle component analysis to construct MDS to determine a comprehensive set of indicators for assess soil quality and established the agriculture practice in the main cultivation regions of A. mongholicus. Our results indicated that the quality of A. mongholicus, based on the quality score of the active ingredients from the PCA, increased with an increase in the soil quality. The five soil factors, soil organic matter(SOM), soil total calcium(STCa), soil total gallium(STGa), soil total borom(STB), and soil total magnesium(STMg), were obtained within 10% of the highest score of the total soil scores and r
