pH stands for soil pH; TOC represents soil total organic carbon content, g·kg−1; TON stands for soil total organic nitrogen content, g·kg−1; TC stands for soil total carbon content, g·kg−1; TN stands for soil total nitrogen content, g·kg−1; TP represents soil total phosphorus content, g·kg−1; TK represents soil total potassium content, g·kg−1; AP stands for soil available phosphorus content, mg·kg−1; AK stands for soil available potassium content, mg·kg−1. Different letters (a, b) on the same row indicate values that are significantly different (p < 0.05) based on one-way ANOVA and LSD post-hoc test.
