# OM—organic matter, TN—total nitrogen, AP—available phosphate, AK—available potassium, TS—total salts. $ Statistical analysis was performed based on the three repeats of each sampling site. Data are average (n = 3) ± standard deviation. Statistical differences between sites are indicated with different letters (p < 0.05).
