Table 1

Descriptive statistics of SOC and SOCS at the two depths.

Variable	Depth (cm)	Mean	Median	SD	CV%	Min	Max	Sk	K	Pk-s
SOC	0–20	21.51	21.2	8.79	40.88	7.8	39.8	0.12	−0.98	0.155
	20–40	17.09	17.45	7.77	45.47	6.9	32	0.35	−1.17	0.003
SOCS	0–20	34.06	32.3	15.74	46.23	12.58	82.62	1.21	2.12	0.047
	20–40	25.85	23.89	13.31	51.49	9.85	65.6	1.29	1.72	0.151

SOC = soil organic carbon, SOCS = soil organic carbon stock, CV = coefficient of variation, SD = standard deviation, Min = minimum, Max = maximum, SK = skewness, and K = kurtosis. Pk-s =  value in Kolmogorov–Smirnov test for normal distribution of data must be greater than 0.05.
