Impact of Site Disturbances from Harvesting and Logging on Soil Physical Properties and Pinus kesiya Tree Growth

Table 2

Total soil porosity (m³ m⁻³) with standard errors in parenthesis as related to depth at the study site.

Soil depth (cm)	Total soil porosity (m^3 m^−3)
	Compacted	Compacted plus tillage	Noncompacted
0–10	0.50 (0.006)^ay	0.55 (0.005)^ax	0.58 (0.005)^ax
10–20	0.47 (0.005)^ay	0.53 (0.005)^ax	0.56 (0.005)^ax
LSD	0.01
CV%	3.8

Note: means with different letter differ (𝑃<0.001). The first letter after each mean refers to comparison between depths and the second letter to comparison among treatments.
