The Spearman’s rank correlation coefficient (r) are shown. Correlations where p < 0.05 were considered to be significant.

TN total nitrogen, TK total potassium, TP total phosphorus, AN available nitrogen, AK available potassium, AP available phosphorus, M moisture, T temperature, P accumulated precipitation 30 days before sampling time.

*p < 0.05 and **p < 0.01.
