The principal component analysis (PCA) plot includes 7 soil properties, namely, total nitrogen (TN), total phosphorus (TP), total potassium (TK), total organic carbon (TOC), available phosphorus (AP), available potassium (AK), and soil pH, for the 60 samples considered in this study. The loadings of 4 nutrient factors—TN, TK, TOC, and soil pH—classified as having low values in accordance with the data from the second national soil survey in China, are denoted by the gray arrows. The loadings of 3 nutrient factors—AP, AK, and TP—categorized as having high values according to the data from the second national soil survey in China are depicted by the black arrows. The abbreviations corresponding to the 12 plants are documented in the Materials and methods section
